    Wolfgang sent me a PM and asked me to comment on my experience with the AF performance of the Sony A7RIV and Sony 90 macro and the Canon 100 macro on Canon dSLR. I was a long term Canon dSLR user (20D, 40D, 50D, 7D, 7DMkII and 5DMkIII) all with the Canon EF 100mm f/2.8 USM Macro. Just over a year ago I changed to Sony A7RIV. Initially I used the Canon 100 macro on the Sony with a Metabones adapter but changed to the Sony 90 macro after 3 months. My wife still uses my 7DMkII with the Canon 100 macro so I was able to compare all combinations of camera/macro lens possible just now. Room was dimly lit. Results varied based on what focus point setup I used on each camera/lens. With all focus points in play and cameras set to AI Servo (Canon) AF-C (Sony) the winner in grabbing focus quickly was the 7DMkII/Canon 100 macro with the A7RIV/Sony 90 macro a very close second (it was occasionally faster than the Canon). The A7RIV/Metabones/Canon 100 macro was a distant third (Which is why I got the 90 macro 12 months ago when I did the same test). When I changed to my preferred mode of shooting with each camera - AI Servo with Expand AF (Canon) and AF-C and Tracking Flexible Spot (Sony) - things changed. The A7RIV/Sony 90 macro was first grabbing focus fastest and holding it better than the 7DMkII which came a close second. The A7RIV/Metabones/Canon 100 macro came third. Points to consider: Before I switched to Sony the 7DMkII was by far the best low light focussing camera I had ever used. Depending on how you set up the autofocus system the A7RIV is better than the 7DMkII with their respective native macro lenses The effect of the Metabones adapter on focus performance will differ from lens to lens. While the Canon 100 macro is slower on the Metabones adapter my Canon 8-15 fisheye (for which there is no Sony equivalent) focusses much faster with the Metabones adapter on the A7RIV than it did on the 7DMkII.

    After many months of lockdown in which we have done everything possible to cultivate our passion for diving, finally we are back in the sea and the island of Giannutri (Italy) welcomes us in the best way. Punta Pennello shoal with its forest of black coral (Antipathes subpinnata) surrounded by forests of Paramuricea clavata and Eunicella cavolini is a riot of color and life and reminds us that the Mediterranean mesophotic coral has nothing to envy to the tropical seas.

    In November I managed to steal an adventure from and otherwise difficult 2020. After getting Covid-19 tested, keeping a temperature log and donning two masks, I ventured to the Socorro Islands for the first time with the GH5 on the Solmar V. I head read all the report of camera housings getting taxed going through customs, but we got the green light when tapping the button and all was good! Spent 8 days aboard the Solmar V with masked crew and divers. The crew was happy to be back at sea again after being shut down for months. I was happy to be back in warm water. Below is the video of the adventure.

    Hi, my name is Marcell Nikolausz. I’m a hobby underwater videographer originally from Hungary, living now in Germany. There was a recent discussion about the underrepresentation of videography topics at wetpixel. I also missed discussions about the lower budget video solutions. I’m very much interested in the latest and greatest tools the professionals are using, but those equipment are way beyond my budget and it’s true probably most of the readers of wetpixel. So I thought, I initiate a discussion about low-budget videography. Is it possible at all? I started with underwater videography already during the film era using a Minolta dynax 7000i in an Ikelite housing. That time the acceptable video quality was really expensive, while I could easily afford the same film David Doubilet used (but my photos were still crap in comparison but not because of the “sensor quality”). Especially wide angle video and proper lighting was achievable only for bigger film crews. Today, a cheap action camera has a better quality at a fraction of price what was available 20 years ago for professionals. I get into videography when I purchased a sony nex-5 and I explored that it has a video record button but I was not really hooked at the beginning. The real change happened when I got a GoPro HERO (entry level version of HERO 4, approx. 130 Euro) and started to play with it and decided to get more into videography. I watched many videos on youtube and vimeo but most of them were really bad with lots of shaky camera movements causing sea sickness on land. The other major problem I recognised was the bad colours but somehow I expected it. So I wanted to make completely different underwater films. I watched also many BBC documentaries and films from professionals. I especially liked the work of Howard Hall and it was clear that he used tripod a lot. So my first suggestion is to use some kind of tripod or some other kind of stabilization for your camera. My first solution was a flat rock. I glued a GoPro mount on it and attached my camera. I also tried joby gorillapod but it’s too light for such small cameras. My second solution was a modified aluminium tent-peg. (see picture below). Not much later I invested into a second camera. Instead of a top GoPro I bought the much cheaper Yi 4K (around 200 Euro that time). (It fits better to the low-budget videography). The camera choice will be the topic of a next post. Overall, it was really fun to use these cheap cameras and I created a short film that I entered to the actioncup video competition. It’s a German video competition focusing mainly on small cameras and it has a category for action cameras. My movie won the freshwater category. See the movie below (Sorry but the text is German but I hope you will watch it anyway): Overall the budget of this movie was around 400 Euro. One short footage from this was even used in a bigger TV film (broadcasted in Slovakia) Next post will be about low-budget but relatively good quality cameras.

    I am happy to share my latest video-interview with Max Ammer, the pioneer of diving in Raja Ampat, West Papua in Indonesia. About 30 years ago, Max came to Raja Ampat in a search of World War II relics. This is a story about how Max built the very first dive resort in Raja Ampat - Kri Eco Resort, and later - Sorido Bay Resort, about conservation efforts of Max and his partners, training local people and building the very first electrical boat in Raja Ampat. Video is shot with Sony NX80, and a few clips with Sony 7Rii. ENJOY. https://youtu.be/vcmAxOhLgEM

    Hi, I would like to share a video from my last trip to the river Traun. The river Traun is the most varied dive spot i know here in Austria. Mainly you dive in a dammed area of the Traun with moderate currents. There you can find a sunken pump room, 500 year old roads from the period of salt shipping, beautiful light under driftwood and under the trees at the shoreline and much more. If the conditions are good, its possible to dive the Canyon at the Traun waterfall. The dive gear has to be roped down, the scuba divers has to jump or climb down the steep rocks to enter the water. The Canyon offers a magic scenery with its washed out rock face, cascades and the crystal clear water of a spring pot Alex globaldivemedia.com

    Hello everybody, I just returned from a 3 week trip to Indonesia. My first week was spent in Lembeh with NAD Lembeh and had the opportunity to go on my first black water dives. Needless to say I quickly became addicted and didnt miss any dives. A quick review of my experience with NAD Lembeh. I will echo most of the reviews I have seen on the website regarding my experience, it was phenomenal. Although this was my first trip to Lembeh and thus have nothing else to compare it to I will say that I will not be staying anywhere else during any future visits. I had a nice room by the beach, bed was very comfortable and AC worked to perfection. The food was fantastic, and they were very accommodating since I am vegetarian. The dive boats are great with ample room for all on board. The staff carry all your equipment to and from the dive boat and set it up, including the camera. The camera room was very ample with lots of charging space. There are computers to edit/post but I did not take advantage of this service. Since I was in a room by myself I had my own dive guide/buddy/photographic assistant which was Andri. He was great, very patient and never in any rush to move on. It didnt matter whether we spent 30 seconds or 30 minutes in a subject there was never any rush. Here are a few shots taken during black water. Critique highly encouraged. Many more to come including during regular dives. Many more posted on Flickr.

    I think the answer will depend on what you mean by underwater photography. Carrying a gopro on a stick is a very different thing than diving with a full kit with tray and dual lights and strobes, with macro and WA swap-able lenses. The amount of dive time will also vary by person. Before you branch out from gopros I would say you need to be able to do a few things consistently and without much thought. Buoyancy is key. You need to be able to maintain your buoyancy even when other things are happening to divert your attention. Particularly early on with photography, trying to figure out the settings and just working the camera takes a lot of focus and with newer divers once they pay attention to that, buoyancy and situational awarness start to fall apart. Once you can keep buoyancy when task loaded that's one sign you are ready Situational awareness. Photography can consume most of the attention your brain can give it until certain things become ingrained through experience and muscle memory. That goes for the physical muscle memory of working your gear and your camera as well as the familiarity to be able to do both without much thought. You should be able to function all your normal dive gear quickly and easily without much thought. S drills, lost mask, reg recovery, etc should be very proficient, and you can do them at any time. Adding a camera system in the middle of these can cause real problems if this isn't able to be handled quickly and easily without much thought. It really helps to get very very familiar with any camera system on the surface, and then with a few shallow dives to work out where your problem areas will be. Each person is going to reach this experience level at different times so its hard to say X number of dives will get you there. If you are diving with a group of divers and one or more is mentoring you, ask them to help you work on some task loading exercises, and work through any buoyancy issues when doing them. You can work on camera familiarity on land. Also if someone in your group shoots, see if you can buddy with them and them let you shoot on a dive to see where you are. If things get to be too much work out a plan to just hand stuff off.

    I've done controlled tests before comparing DivePro 18k lights vs. the Gates GT14s and Keldan Luna 8s (13k lumen model). The tests are somewhat complicated by the fact that the DivePros' output is concentrated in a ~90 degree cone, similar to the Gates GT14s, while the Keldans are closer to 110 or 120 degrees. Because of this, the actual amount of light for the Keldan that falls upon the subject ends up being half what you get from the DivePro and the Gates GT14s. The difference between the Gates and DivePros was not measurable in fstops. So.. I wouldn't worry too much about the cheaper 'chinese' lights meaningfully exaggerating their light output. Keldan certainly has nicer controls and better reliability. My dive buddies and I have experienced issues with DivePro cannister lights in cold water (4 degrees) where multiple units just stopped working for no reason. Clearly, the quality control and testing under challenging conditions could use improvement. But in my view Keldan made a serious mistake by using dome ports on the front instead of flat ports. A 90 degree beam is more than enough for video unless you're filming with a fisheye. I note that the X-Lights also use a dome port, which is silly.

    Yes, but believe me, he is rock steady. A human dolly. Just look at his old videos before GH5S. Here he experimented with shallow focus. Perfect lightning. He creates a lot of shadows enhancing 3D and super CC. Keep in minf he's at 80m freehand. No camera, no scooter.

    I would like to see more video related contents. I think the platform is given, we, video content creators should just put more effort to share our experiences and discuss video-related topics here at wetpixel. I was not that active so far, but I'm planning to start a new topic on "Low-budget underwater videography".

    I have been ask a bunch of questions about all things A7C and today my 4000 word review has posted in UWPMAG.com issue #119. This is a free PDF download and I suggest you read the review if you have an interest in the Sony A7C. I intensely did my review using only the Sony FE 28-60mm "kit" lens with the WWL-1, WACP and one and two CMC-1 lenses. Some of the macro is in this thread. After reading the review I would be happy to answer any questions. The attached image is with the 28-60 at 28 using the WACP. This is an A/V light shot at ISO-400, F10, 1/125th sec.

    I recently took this shot on a trip to the Souther Great Barrier Reef. It is my best example of balancing flash & ambient so far. I put my lower strobe on a very low power setting tucked in close to the left handle and had the upper strobe on a high power at full rabbit ear position. Hope you enjoy looking as much as I did making it Thanks,

    Just did my first dive with the R5 and thought I'd share some sample footage (youtube links below). It's nothing special, just a few different scenes to give you a feel for the image quality. I have the camera in a Nauticam housing with ZEN 230mm dome, using the RF 15-35mm. Settings on all these videos: 4K 30p, HQ mode (oversampled from 8K), ALL-I compression, Canon Log on. Files were edited in Premiere and exported in maximum render quality. Footage was shot on St. Eustatius in the Dutch Caribbean. All videos are shot at around 70 ft depth, conditions were not great: it was an overcast day, still early in the morning, so not a lot of light or colors available at that depth. No artificial light was used, just ambient light. I used a white slate to manually white balance the footage, which is a bit of a hassle on the R5. Taking into account these low-light conditions, I think the camera produced some fantastic video. I am sure though the footage will be much more vibrant in shallow water with more sunlight. Interested to hear what you think. Happy to upload more footage with different settings next week if anyone is interested.

    Very happy to see the return of this topic! My fave reflects my long-term salmon project that was influenced more by the weather that was excessively wet in 2020 and poor salmon runs than by covid. I took this shot during one of the few and short sunny spells in early July before any salmon had returned to this stream. I used a lens that I had used for this same purpose (juvenile salmon) but with film back in the 90s, the Nikonos RS 28mm. This was one of the lenses that Harald H brought with him to DEMA in '19 following the SEACAM mdification. I have used several other lenses for a similar purpose but was challenged by the nature of underwater optics. This lens has a much flatter field as well as being a sharper water-contact lens. Its small size also helped as the lens was not completely submerged due to the shallow water depth. Rocks on the bottom (get in the way) did not help either.

    Hi everyone, New member here, thought I'd introduce myself with some shots from my home country, Scotland. These recently featured in the Dive Photo Guide photographer of the week. Having some trouble linking images from elsewhere so here's a link to the article and a small sample. http://www.divephotoguide.com/underwater-photography-special-features/article/underwater-photographer-week-mark-kirkland

    Nice images, Adam. However, obviously it all depends upon one's situation and subject matter. Not everyone shoots large subjects in open water with artificial lighting. I'm normally shooting small subjects in shallow freshwater streams with natural lighting. And yes, many of my wide angle shots could not be gotten with a large dome. Here are a few examples with subjects less than an inch from a 4" dome (closer than a large dome could get) and/or with the housing pressed against the stream bottom (lower than a large dome could get):

    I'm pro lanyard all the time. I clip on a coiled lanyard as soon as I splash. I have had to deal with critical safety and rescue scenarios more than once under water where there is no time for spare for the camera. Not having a lanyard already in place means you either don't deal with the emergency when needed most, or you lose the camera.

    For many years now I have been diving in the Mar Piccolo - Taranto (Italy) at all times of the year. I discovered this place 25 years ago thanks to the collaboration with a local scientific foundation and since then I have never missed an opportunity to return. In recent years, however, the summer temperature of the water reaches almost 30 degrees, creating great problems for the local fauna and flora. Many species move towards deeper waters and others, unable to move, end their cycle with a slow agony. I returned in these days and this little Mediterranean paradise is starting to revive.

    Here is an example I shot last week with a similar setup to yours, using a D850 / 15mm Sigma FE / 170mm port + Inon 330 strobes. The left strobe arm is 12+16+8 and the strobe is pointed inward from the upper left. The right strobe is closer in to the right an pointed forward. ISO 250 / F9 / 1/80s Left strobe is -1.5ev, right is -3ev. The water conditions in Puget Sound were relatively good by local standards at 25 foot visibility but this is heavily particulate water. I did not do any Spot removals of backscatter, but I did bring down to 0 to the Clarity/Texture (midtones) of the green water using LR. You can see there is hardly any distracting backscatter in the image. The point of using a lower strobe power is that you don't illuminate the backscatter nearly as much in poor clarity water. You can boost exposure in post processing to get the brightness you want for the image, selectively if needed. I shot at -1.5ev & -3ev which is about 1/3rd and 1/8th power for the two strobes. If I shot in these dark and chunky waters at Full or Half power the image would be blasted out. If you want a darker background use a faster shutter speed. 1/125 or 1/200. The strobes don't impact open water background color. Shutter speed controls ambient light.

    The original version of this trip report was posted on the front page of Wetpixel a few weeks ago, but I have now updated it and added some new images on the version I have done on my site. Here is the link to Diving the Witu Islands All the wide-angle images were taken with a Nikon D500 and 8-15mm lens in a Nauticam housing with the 140mm port, which I personally find to be really great combo. The macro images were taken with the 40mm Micro-Nikkor - I screwed up in the last minute packing and left my 60mm and 105mm macros behind... As they say the best lens you have is the one on your camera! I have been visiting Papua New Guinea regularly for 20 years, but this was the first time to the Witu Islands and I really was impressed. When you look at the location of the islands in the Bismarck Sea, relative to the rest of the Coral Triangle, it becomes clearer why they are such so biodiverse. Here are a few images to illustrate what I mean. Don

    This is the final cut of my semester project for film class at the Academy for Creative Media Windward. Due to the COVID-19 shutdown I was reliant on b-roll that I filmed during an expedition to Cocos Island, Costa Rica in early March of 2020. This is not a "creature feature", more an experiential film to guide the viewer on a virtual dive in the Deep See submersible. Filmed aboard the Undersea Hunter Group’s M/V Argo, on location at Cocos Island, Costa Rica. Best viewed in 4k, with good speakers or headphones... -Brian

    Hi Divers Sadly we can't dive in Thailand these days and I miss it badly. But it's given me time to do something I've wanted to do for a long time, to rewatch and rank my favourite underwater documentaries. So I made a video about my top 10 favourites. What's your favourite? Check out my video:

    Cause I’m using the GH5s which lacks IBIS, I had to come up with a way to balance my rig to to make it feel like a traditional video cam rather than the DSLR restricted position. This setup up helps me avoid all types of roll, pitch and yow. It is not a final setup up but it is so balanced that I can let go of the camera midwater and it will just stay there :). I rely totally on the external monitor for all my needs: exposure/focus etc... I can adjust the camera vertically (lookup/down) by adjusting the DIY floors position.

    I took a trip aboard the MSY Seahorse in the Banda Sea back in late September/early October. The primary goal of such a trip is to see schooling hammerhead sharks. This was my second attempt and managed to get some good footage of them. It's really quite a challenge to capture them well as you never know when they will show up and how close they'll be. The GH5 has a hard time focusing on such a subject in the water column at a distance. My strategy each dive was to swim off the wall, turn around and focus the lens on a contrasty area on the verge of visibility. Then, I would keep my fingers away from the focus lever for the rest of the dive! When we finally encountered the school, I had to make a few short fin kicks towards them till the focus peaking appeared around them on the monitor, then pressed record! Here is the video of the trip. Comments and critiques are welcomed.

    Thought i'd posted this before but i don't think i did. A slightly-too-long compilation of 3 days of Oceanic Mantas at Black Rock in the Mergui Archipelago, Myanmar. Very unusual trip in that (i) lots of mantas there and (ii) the visibility wasnt 5m of green for once! Underwater shot with a Canon EOS70D with and without a magic filter. I know there are frame rate stutter issues in places. No sound track as i dont actually have any music stored locally to put onto the footage.

    Hi, a video from my 2nd winter stay at East Greenland. We dove in the fjord in front of Tasiilaq. My plan for this video was to capture the elemental force in this region. I wanted to show time lapses of moving ice during the tides, under- and above water, and mix impressive icebergs with macro footage. A big thank you to Sven from Northern Explorers who supported my ideas and let me do what I wanted! The video is actually in the order as i experienced the trip. As i arrived we still had some left over packice. a few days later the winds brought icebergs in the fjord. After a week hundreds of iceberg right next each other were stranded in a bay. Unfortunately the last week the climate change said hello, and we had unusual warm weather for this time of the season and rain. We can´t went out on the snow mobiles anymore, because all the snow was melted away in only a few days.. And at the dive spots which were in walking distance, the viz droped to 5 meters due the melting water which were washed in the ocean. The video was shot in 7 to 8 days, on 13 dives. Enjoy watching! Alex.

    Hi, I want to share my latest video with you In winter I have been at the White Sea in Russia for ice diving and i was curious how the landscape and diving might be the rest of the year. Because i like the indian summer colors i decided to come back in autumn. My plan was to capture the autumn mood at the White Sea and create a story around a leave falling and sinking in the sea. On the spot it turned out that this story is not far-fetched, because leaves constantly flushed by the tides in the sea. So, have fun watching! globaldivemedia.com

    1) the WWL-1 does not come with a buoyancy collar. They sell a hard foam one. The 1B has a metal buoyancy collar that comes on it. If you get the 1(A?), I think you really want a buoyancy collar for it. AFAIK, the lens itself is the same. At least, optically speaking and how it mounts to your camera. 2) You don't need a focus gear - unless you want to use Manual focus. I don't have the focus gear for the 28-60 lens and I can't see myself ever needing it. For fine focus, I would be more likely to just let AF get it very close and then rock back and forth a little bit to adjust the fine focus. 3) If you want to use strobes, you need a strobe trigger. It doesn't have to be the Nauticam one. I am using a UWT (Underwater Technic) and would probably buy another one. It supports using TTL mode (which I have not used, but do intend to play with that soon). I tried a Trt S-Turtle trigger and had poor luck with it and Trt's customer service. I don't know if the Nauticam trigger supports TTL. You have to decide if you want that option (to be ABLE to use TTL) and then make sure the trigger you get does support it for your camera AND your strobes (if you want that option to be available to you). 4) You don't HAVE to have a vacuum valve, but it is highly advisable. The Nauticam one is working very well for me. I think BS or BW also has their own branded one, that you could go with. Which one is really up to you. The Nauticam housing should have a built-in moisture and vacuum detector. If you don't have a vacuum valve, then you won't be able to take advantage of the vacuum detector (which detects LOSS of vacuum). You'll only know if you have a leak when water gets in and sets off the moisture detector. A vacuum valve is cheap insurance for an expensive camera. 5) My Inon Z240s have been rock solid. I had a terrible time trying to make a new pair of Sea&Sea YS-D3s work for me and ultimately sold them. If you search around this forum, you'll find many others with the same complaints I had regarding using the S&S. People with offboard LED flash triggers (like you will have with an a7c) struggle to get the S&S strobes to fire reliably. People with cameras that have a built-in flash, generally have good luck. Also on the subject of strobes, my opinion is to buy the biggest/best you can afford. If/when you ever change camera systems, strobes will move right over. Unlike your housing, etc.. Strobes are an even more long-term investment than the camera itself. I'd take Inon Z330s over Inon D200s - unless you want the D200s for size/weight considerations. If necessary, I would even buy 1 Z330 over 2 D200s, to get started, then save up to buy a second Z330 later. 6) You don't HAVE to have a focus light at all. But, they really do help the camera focus more quickly and accurately in low light. I use my focus light all the time (for wide angle) and for small (but not macro-small) stuff. I haven't ventured into actual macro shooting yet. Fortunately, a focus light does not need to be expensive. Low power is better than high power. You don't need it to automatically turn off when the strobes fire. Strobes are so much brighter, a low powered focus light won't affect the picture when it stays on during the exposure. So, pretty much any small, low powered dive light will work just fine. I use a very inexpensive, relatively low-power video light as my focus light. It throws a nice wide beam, so I don't have to worry about aiming it precisely, and I can get focus lock on a subject, with tracking, and then recompose and my subject will still be illuminated to help the AF tracking.

The discovery in 2016 of a garden of Savalia savaglia near the largest islet gave us the opportunity to learn more, with Prof. Carlo Cerrano, the peculiarities of this species and its ecological and biological value. The dives also highlighted a particular type of interaction between the two typical chromatic varieties known for Savalia savaglia. The observation opened new hypotheses on the complex growth strategies of this species. The opportunity provided by this type of exploration underlines how technical diving is a means and not an end. A set of tools that allow to extend the duration of our excursions, to approach demanding dives making them safer and more fun or, as in our case, an example of "citizen science" that is a collaboration between technical divers and scientists.

    Hi all, very few UW photographic opportunities for me in 2020. My best day was spent with the blue sharks of Penzance, Cornwall, UK.

    I got my a7s3 and Nauticam gear just before a big dive trip in the Caribbean in late November. Shot three Sony Profiles settings, sLog3/SGamut3.Cine, HGL3 and No profile. File format:XAVC S 4K at 60fps10 bit 4:2:2 for all profiles. Customize the C4 function for white balance (So I could execute WB in right hand UW and hold Grey slate and later chip chart with left hand). I used official Sony LUTs and Leeming LUTs in post for evaluation of clips. Will edit in FCP and finish color in Resolve. It was a well balanced neutrally buoyant rig with Keldan 4x Lights, red and blue filters were consistently used. I was hoping because of the lowlight capability of this sensor to shoot with no lights so as to not scare off fish. In field evaluation I sensed that just a bit of light made a huge difference in color accuracy and saturation. So after a 3 dive and no lights I shot the remaining 20+ dive with light. My takeaways: 1- Love the setup, would choose sLog3 if time in post permits CC, If not post time then I would go with no profile. You lose 1 maybe 1.5 stops of latitude but generally clips were nicely saturated and accurate. I understand some people think the sony color science is to be avoided but I saw no issues. In also I preferred Sonys LUTs over Leeming LUTs for 90% of the shots. Whats my experience in Video color science? 40Plus years surface shooting and a successful life doing so. UW shooting is just my hobby, 2- I used SDHD cards for the XAVC s 4K file format and they bogged down a Late 2013 Mac Pro with 32GB Ram and top end graphics cards. Had to use proxy's to not go crazy in post. I did buy and have tested the new Sony CFExpress Tough card and "I think" it performs well enough to be able to avoid proxies in post. This is because the CPU has to do less calculations than with a codec that has more compression. I did a surface shoot yesterday (Birds in Flight) using sLog3 S&Q settings for 120fps with XAVC S I 4K and I filled a 160GB card in well, not very long. Luckily I had a laptop to download to continue shooting. Take Away 2.1 if you want 120FPS you better mean it! Or have lotsa expensive cards. Moving them into post and seeing performance will take place in a couple days (I hope). Apologies on long post, but a couple further observations. Cost, yea I'd say camera "May" be a1/3 of the get in the water costs. so, lights and floats, buy the best you can. Housings often are sacrificed if you go for a new camera, but odd note here, I have an a7R4 and it goes in the a7s3 housing. Most of the buttons on the top work but the only button on the back at seemed to work was the Disp button. I am exceptionally happy with this my 3rd rig. Should be able to last the rest of my life. Knock on wood!

    The Zeus faber or John Dory is certainly one of the most representative fish of the Mediterranean mesophotic zone. The John Dory has a high laterally compressed body: it's so thin it can hardly be seen from the front. The large eyes at the front of the head provide it with the binocular vision and depth perception it needs to catch prey. It hides among gorgonians and catches prey by stalking it, then extending its jaw forward in a tube-like structure to suck the fish in. I am always hypnotized by the ability of this fish to advance while remaining with the body motionless while moving only the anal and dorsal fins with an infinite vibration. These two specimens were filmed on Giannutri Island at a depth of 75 meters (250 ft.). In the central clip (00:48) there are 3 other mesophotic citizens: A basket star (Astrospartus mediterraneus) , a melon sea urchin (Echinus melo) and some colonies of red coral (Corallium rubrum). ------------------------------------------------------ Audio track: Antigravity 2 by Dan Skinner & Adam Skinner - via Audio Network Cover photo: Marco Bartolomucci

    The debate has taken unexpected turns. Instead of continuing to mourn Olympus or betting on who will be next (Nikon?), comments on children and young generations reminded me of two essays by Italian authors: Massimo Mantellini and Paolo Magrassi. which perfectly center the side theme slightly touched by @oneyellowtang and @Interceptor121 "We live in the "good-enough society", the age of good enough: we don't need the optimal quality of the CD, MP3 is enough; phone calls with perfect audio? Skype VOIP is more than enough". The Internet has radically changed our approach with depth, information, social relations, markets and culture. We listen to music in new digital formats, we photograph the world through the small lens of our mobile phones. We no longer read newspapers, preferring random information that bounces off the social profiles of our "friends". But we embraced Ikea kitchens and Banksy's graffiti, new low-resolution artifacts that fill our lives today. Often through such options we can glimpse the signs of a new intelligence, other times they tell the story of our usual superficiality. In low-resolution technology real time overwhelms the archive. The Internet, the place of memory, is transformed into the space where everything will be quickly forgotten. Let's take music: while still discussing whether vinyl or CD is better, we switched to mp3 and then to streaming. It all happened quickly while we were discussing which are the best gold cables for our high fidelity systems dusty in the living room. Then I go into my son's room and his tech equipment is very simple: a laptop connected to the internet, Youtube and two $10 plastic speakers. If I ask him "how does it sound?" the answer is "great". It sounds great. We can do the exact same thing for photography. The current transformation is similar to the revolution introduced by Polaroid in the era of film. The digital image has changed skin and is now dominated by the speed of the transition to new media other than paper: social networks where our friends will be ready to welcome them and comment on them. The low resolution at least in our photos is not a simple process of degradation for practical purposes but a complex process that expands in several directions. A significant number of photos we see on the net are low-resolution but highly processed images. The software that modifies them before they are published is equipped with predefined filters and options that allow in a few gestures even on the screen of a mobile phone to make the image we have just taken more interesting, artistic or captivating. Such modifications are improvements and adulterations: They make the photos more similar to us and to the idea that we want to suggest us to others, but they intentionally betray the principle of truth. above all, they make the photos that we observe on the net all substantially similar. It's no coincidence that there are now groups of people on the internet who would like to eliminate the use of filters and who add the proud caption "nofilter" as proof of the authenticity of the look that technology has now compromised and deceived everywhere. Within the vastness of the digital offer, everything seemed at hand. Just then we decided to slow down, making an unexpected choice: the reduction of our expectations. Understanding this choice means understanding the contemporary. Low-resolution

    Hi all, Here I am with my latest effort. You have English and Spanish subtitles Bottom trawling is the most common and destructive fishing practices in the Mediterranean Sea. Bottom trawling represents a major threat to the seafloor ecosystem. Yet soft bottoms are not desolate stretches of sand but complex ecosystems, populated by organisms that are fundamental to the conservation of fish stocks. Giannutri island, part of the Tuscan Archipelago National Park, is a good example of intact marine environments. The fishing ban up to three miles has preserved intact deep habitats and the particular morphology of the island's seabed allows divers to reach the "twilight zone" (i.e. he bathymetric range between 50 and 120 meters.) in a rather simple way. Trimix, DPVs and rebreathers are perfect tools for observing still extremely intact deep environments with less invasiveness. These protected areas suggests how protection, if properly managed, can effectively maintain integrity in environments that host hundred or thousands years old organisms and provide us with natural laboratories where we can study what these environments would be like if they had not been damaged by human activities. On a technical perspective An alternative title of the video could be "History of Panasonic underwater". In the video there are shots taken over many years with my GH2, GH3, GH4 and GH5. So from a technical point of view I'm not at all satisfied with the quality of the footage which in some cases I consider to be very bad. I'm not a professional; I have witnessed some phenomena in a completely unexpected way, with the poor beloved GH2 at 100 meters in winter sea at 1250 ISO or at the end of a dive with flat light batteries. The important thing for me was to be able to communicate a message.. Bye

    Excellent photos. I can only contribute with videos, because in the last few years I'm switched from photography. Sorry for the German text but it was a submission to a German underwater video competition. The footages were taken in German lakes close to Leipzig.

    I found the time to do a little write up on underwater white balance that includes some of the techniques I use Hopefully this is useful to most people out there. I have focussed on GH5 picture profile but I guess other camera won't be much different https://interceptor121.com/2019/09/24/the-importance-of-underwater-white-balance-with-the-panasonic-gh5/

    Honestly, it isn't that complicated... Looking through my A6300 menus, I have, among those that are relevant: Quality: RAW - there is no real reason to shoot JPEG underwater Drive mode: single - can't really shoot bursts with strobes and pop-up flash, maybe with a LED trigger and low power Flash mode: rear curtain sync Focus mode: DMF for macro, AF-C for wide-angle Focus area: Center AF illuminator: Off AF drive speed: Fast AF track sens: High ISO: 100 for macro, auto 100-800 for wide-angle Metering mode: Center White balance: Auto SteadyShot: On Zebra: Off - it's useful for video, kind of useless for stills with strobes Grid line: Rule of 3rds Auto review: 2sec - wish there was a 1sec option Peaking level: low for macro, off for wide-angle Peaking color: yellow Live view display: Setting Effect OFF - this is important, as if you turn it on, camera will focus with aperture at your set setting rather than wide open. With it off, it will let it maximum light for focusing, and close the aperture as you take the shot. Priority set in AF-S: AF Priority set in AF-C: Balanced emphasis AF w/shutter: On, but I use a trigger extension. If you want to use back-button focus, this goes to off. Exp.comp.set: Ambient & Flash Monitor brightness: Sunny weather Power save start time: 1 min As far as shooting goes, I keep it in manual mode, f/8-f/13 for wide-angle with 10-18mm or 16-50mm, f/11-f/16 for macro with 90mm, f/22 for supermacro with 90mm and +13 close-up lens, 1/160 shutter most of the time, a bit slower if I want a brighter blue background. Sometimes I play with flash compensation a bit if I feel that TTL isn't doing the best job. Display mode is almost always the electronic level; it makes a very handy reference. I shoot with both hands on tray handles, triggering via an extension on the right side. Don't really push buttons much while diving; right hand only really leaves the tray handle to adjust aperture via top knob or shutter speed via rear knob.

    I've used the WACP with 28-70mm on several trips over the past year and am impressed with its versatility of FOV range. I believe that is about as close as you’ll get to having your cake and eating it; for now, with full frame. Some examples. At the narrow end (70mm->75degrees): http://www.underwaterdisplay.net/dive63/FJ190513_3215.jpg http://www.underwaterdisplay.net/dive63/FJ190514_3382.jpg At the wide end (28mm->130degrees): http://www.underwaterdisplay.net/dive64/MOR20191007_5670.jpg http://www.underwaterdisplay.net/dive64/MOR20191004_4678.jpg Downside is weight in lugging this beast down a beach but once in the water it’s a thing of beauty. In Moorea recently we did a lot of swimming in the blue and there wasn’t much difference in water resistance (possibly less) between my rig and those using large domes.
