If 5DM4 has 4K, it will kill their XC10 since XC 10 price around 5dM3 or 5dM4, but 5dM4 has full frame sensor, interchangeable lens, takes photo.

Nice work as usual Dustin! Like the different view of the plane. May be because I don't have knowledge of the plane, I think it would be nice to have divers around for scale reference? I mean the plane looks really big during the top down view of the plane at 2:45 but I have no idea how big.

Not sure what muddled 1080p footage you are referring to, but footage from a 5d II or III isn't muddled.  4k does look nice sampled down to 1080p, but that doesn't make 1080p footage muddled.  To me, color is everything...It's what captivates the viewer, along with the subject being shot.  Detail is nice, but I don't think its lacking by any reasonable camera made in the last 5 years. 



I'm sorry, I need to clarify that. What I mean muddled is when watching 1080p footage on a 4K monitor. Just like SD/DVD get pixelated when watch back on a 1080p monitor.

#359613 How would you shoot this scene?

Posted by kc_moses on 04 April 2015 - 07:10 AM

Thanks Nick!


I had the focus on the sand/burrow in the beginning, so when the eel poke its head out, it was focus. I thought the eel would just stay straight out of its burrow, but whole know it gets so long and dances in between the fish! I have another clip where the focus was on the fishes, I was hoping that when the eel is in the fish area, its head would be in focus together with the fish. Yeah, I swear a lot, not to mention there were lines of diver behind/next to me waiting for their shot.


It was definitely and interesting experience, not sure if I will get the chance to see this kind of behavior a lot. Let's hope the next time I would better shot!

#359375 LX100 Underwater Video - Anyone else have experience with the LX100

Posted by kc_moses on 29 March 2015 - 02:11 PM

Here are two screen capture of the LX100 shot with ISO800:






The Octopus is night dive, while the Nudibracnch is day time with custom white balance without video light. As you can see ISO800 on the LX100 is usable and pretty good, just not on scene where you have lot of blue color water. The Sipadan LX100 clip posted at the top of this discussion shows very nice/clean  blue, I'm not sure if it's because the diving condition in Sipadan is much better than Anilao, or the fact that the Sipadan clip is 1080 instead of 4K sort of hide the noise at the blue part of the clip.


I'm still going through my clips, I have about 800 clips! If I found some that show the water column in ISO400 or ISO200, I will post it here for people to judge/reference.

Posted by kc_moses on 28 March 2015 - 08:48 PM



I used Magic Filter with the LX100 during my recent Anilao trip. I have an extra 2x2" Magic Filter from a while back when I bought a pack of three. The 2x2" is more than enough to cut to size and stick on top the lens before putting the camera into the housing. You do loose a bit of light, but it won't be a problem in tropical water. The weather condition in Anilao turned cloudy so I stopped using it after 1 day.


Here is the screen capture of the dive when I used the Magic Filter + Custom White Balance:



The dive was in the morning around 9 am. I shoot the video in Manual mode, Shutter: 1/60, ISO 800, either F8 of F11 (I don't remember). To get the best result out of Magic Filter, the sun should be behind the shooter. I have to say, Anilao is not a good place to shoot wide angle video because the water just have too much sand/murky. There were a lot of traffic in the area so the sand could be caused by diver stir up sand as well. I was with a group of U/W photography, they had workshop so in mid trip everybody switch to WA and I'm stuck with them. Feel like I just joined a group of people travel to Asia to eat McDonald.......I wanted more macro dives!!!!!




PS: ISO 800 is too noisy for WA, ISO400 is the max I would go if you have a lot of blue color water to show in your composition. I used higher F-stop because I wanted more flat depth of field, and paid the price of needing to use high ISO. Good thing the LX100 can open up to 1.7F so that's not an issue, I would choose low noise video over flat depth of field from now on.

#358025 GH4 - Nauticam Macro Lens/Port Thoughts

Posted by kc_moses on 18 February 2015 - 02:04 PM

Well, from my experience, the manual focus would be handy. Say if you shoot at Manual Focus mode, you use the back button to set initial focus, and shoot the nudibranch. As it craw toward the screen, you have to pick up the camera and move backward, or use the back button focus technique to refocus again. But if you have a manual focus knob, you can actually "pull focus" and smoothly adjust the focus. I found that using the back button to re-focus a subject that just moved would give the effect as if the camera is focus hunting.


Sometimes when you use the back button focus, it might just focus on the face (like the seahorse), but the eyes is not that focus, just the snout of the seahorse is sharp. This is when it would be nice to have the focus knob to bring up the enlarge screen and really focus on the eye especially with the help of peaking. I don't use pinpoint focus so this is the way I did when I test out the GH4.

Reef Photos came through again, and I will be receiving the 1st production unit CMC-1 in the US, just in time for my Asia trip, flying out in 5 days!!!!!  Looks like I will leave my Aquako IV in my spare diving bin at home and use it for something like a GH5 in the future.

#357901 GH4 Color Profiles - Which One(s) do you use?

Posted by kc_moses on 16 February 2015 - 07:31 AM

I tried CineD and CineV didn't find much difference, I was grading them so it doesn't matter to you. I have quite a bit experience with Panasonic LX-7, took me a couple years to figure it out. If you want nice blue color, use the "Scenery" because it brings out the blue. I tried Natural and the blue seems washed out to me.

Nice work Bob! What color profile did you use? The color turn out well!

#357768 Choose your weapon: SLR versus video camera for filmmaking

Posted by kc_moses on 12 February 2015 - 12:49 PM

OMG!!!! Make sure you watch the video at the bottom of the page, not sure is real or not, but for someone sitting from the side line, I really ask why someone would pay $13000 for a C300?



#357672 Choose your weapon: SLR versus video camera for filmmaking

Posted by kc_moses on 10 February 2015 - 10:54 AM

I have mixed feeling about the article. I don't think Canon C300 or Red is for Advance shooter, they're more for professional.


I was looking at Sony AX100, with a Recsea housing, the total cost is about $7000. You pay that money, just use it and may be add a diopter here and there.


I did the pricing on the GH4, with port, gear, arm, float. It come close to $7000 to cover macro and WA, but the process is overwhelming (coming from a point and shoot person). Balancing on the GH4 (or any Camera system) is tricky too, how much Stix float do you need? If you use different lens/port, the camera become off balance. If the arm is too wide, or too forward, the camera tilt. This is where I feel that I favor camcorder.


Most of us travel would also do top side photos, so a gadget that can do two jobs is great, especially airlines try to squeeze money out of carry on luggage these days. Camcorder housing are huge and expensive, there is no camcorder housing that's less than $1500, and you're at the mercy of housing manufacturer whether if they will make a housing for the camcorder that you want to get (BTW, how come Nauticam doesn't make housing for camcorder?)


I think the article is overly generalize about either use goPro or high end camcorder. There are many of us who are in between, and debate if we should use prosumer point & shoot, compact mirrorless or get the full frame system. Those decision are made base on budget, dive experience/skill, photography/videography technical skill.


The way I would sum it up is:

- Vacationing video for family viewing, yeah, goPro is mostly good enough.

- To put video out on the web for public viewing, trying to be creative/artistic or even enter video contest, camera or something that fit the bill would be the way to go because of equipment budget.

- Stock video, National TV documentary or anything highly commercial, use the RED to your heard contain, after all, it shoot more than 4K.

6.) Make sure the longer screw is longer than the tab and hinge.



7.) Now put together the 67mm holder with the flip frame, but this time the holder is at the bottom, where the flat port would be.



8.) The extra screw length is covered by stainless nuts, and also make it more secure.



9.) Once the whole thing is put together, the nuts are facing out, and the holder is at the bottom/inside.



10.) The Flat port itself has a bit frame, so the 67mm holder will press against it instead of the clear window. But the flip diopter still can be latched close.



11.) With this modification, you don't need to use my suggested  "workaround" of using Step Down ring and spacer, then screw the 52mm diopter from inside of the flip diopter.



Thought & Warning:

1.) Unless you have confident in drilling the holes through and make thread into the holes, let the professional do it!

2.) It only cost me $20 to get the holes drill and threaded, the long M4 screws and nuts cost me less than $3, so total $23 for this mod.

3.) This mode will void your flip diopter warranty, so do it at your own risk, I'm not responsible to any damage you do to your Flip Diopter Holder.

4.) I believe having the frame close to the flat port, you get a few mm smaller width, I have to review my test pictures to confirm.

5.) You can always put the 67mm holder back to the front as it was before, so this mod is reversible if you want to use the CMC-1, which has protrude back.

Thanks Adam, will look into Reefnet diopter.


Shoot for cropping is an option for 4K to 1080p down scaling as there is no pixel quality lost. I agree that it's best to plan to shot the way you want to use it. When I tried out the GH4, with uncontrollable movement because of macro and not having a tripod, it's nice that a light bulb comes on and I switch my brain to shoot 4K with possibility of 1080p, so I reframe my subject not too close to the edge to give me room to stabilize and crop during post.


Those who're curious about LX100 or some other camera, this review sums up all (I think!) the features that the camera has, it's quite exhausting to follow because the camera just have that many features!:

Hi Chris,


I haven't receive info about when the flip diopter will arrive, so I don't know when I will get it wet. My next trip would be to Anilao, so I still have some stuffs I need to consider to get great Macro video. I think I might get the $220 Flexitray with handle since reusing my ULCS handle and tray for a tripod set up is hard.
