#391140 IS IT WORTH IT? GH5s - No Stabilization

Posted by kc_moses on 11 January 2018 - 07:00 AM

At 2:07


About 90ft, cloudy day, no more than ISO400, around F5 with my LX100 (it's similar to GH4). This show there is a need of low noise performance for UW.


Everyone should know the limitation of their gear and push that limit and know what they want/need. So with GH5s, it may help with the situation in my case? May be. But without the IBIS, when you deal with cloudy day, deep, and strong current, would one choose Gh5 or GH5s? It all come down to how comfortable you feel about fixing, either fix the noise with NeatVideo, or fix the shakiness with After Effect Warpstabilizer.

#391049 IS IT WORTH IT? GH5s - No Stabilization

Posted by kc_moses on 09 January 2018 - 06:12 AM

I believe the GH5s do not have the IBIS because of the need of multi-aspect ratio. As for which one to get for Underwater, the GH5 with IBIS is the way to go. The IBIS is critical when you pan and follow a creature. You're not running with the GH5 so you won't see those Jello warping effect of IBIS people say when use on land.


If you're concern about noise, just supplement with high power video light, or there is solution at post that yield very good result, such as NeatVideo plugin. The GH5 also shoot 6K anamorphic should you grow to incorporate more land base video. GH5s just doesn't have enough megapixel to do that.


Also, it's critical to learn to shoot manual focus (utilizing "Back button focus" technique), so all the DFD Auto-focus issue of the GH5 shouldn't be much concern.


If you're not in a hurry to upgrade, and can wait for a year or 1.5 year, Panasonic should have an 8K camera out just in time for the Summer Olympic.

#390873 GH5 tripod leg suggestions

Posted by kc_moses on 05 January 2018 - 06:22 AM

Home made solution, much cheaper:








I use the Mangrove plate, took apart a cheap $67 aluminum tripod for land use, attached a ball mount to the tripod leg with "Instamorph", put a screw and nuts through the Instamorph where the leg join the plastic and it's done. I recently use it in Tiger Beach, very stable. Since it's made out of aluminum, it's light weight and won't rust. It could be a bit long but with enough room on the floor, I can get the camera down to 2" above the ground.


Also, I haven't practice it, the long leg has an advantage, I can push it against my body and use it like a shoulder rig if I want to. Here is me in action, it's not that big once you get use to it:



#388573 Any LX10 in the wild?

Posted by kc_moses on 20 October 2017 - 04:40 AM

The LX10 would be considered as an "Upgrade" if you are want to shoot macro 4K video because the crop factor would make it about 108mm. For the LX100, the macro 4K video is only around 87mm after crop factor. In term of setup, the LX10 gives you the most bang for the buck because the complete housing, tray and vacuum can be purchased for US$1250.


The LX100 complete setup could be expensive for point and shoot:

- Housing: $1200

- 67mm short port: $180

- Flip diopter (it's the only way you can use macro diopter) $220

- Flexitray II: around $250

- Vacuum valve: $220


If you are new to UW video/photo, I would say the LX10 is a good starting setup and is budget friendly.

#387967 4K to 1080 Pros & How To

Posted by kc_moses on 27 September 2017 - 11:29 AM

The recommendation is to put your 4K clips onto 1080p timeline because the performance/editing experience is smoother:



I don't output to 1080p so I can't speak for personal experience.



#387596 Keldan 8x - flux or CRI?

Posted by kc_moses on 15 September 2017 - 05:18 AM




In addition to Burkhard's comment above, could someone who has been using red lens filter and and Keldan Ambient Light Filters (http://keldanlights....nt-filters.html) share their experience as well?


I am considering buying Keldan video lights (8X 11000lm CRI92) in combination with a red lens filter and ambient light filters.  From my correspondence with Keldan and this forum, I see some theoretical  benefits of using this set up.  For example, if I am shooting a giant manta say at 30-40 ft (10-13m) and I have red lens filter and lights with ambient filters on, and I will start shooting when manta is far away from me, red lens filter will help to correct color, but lights will have no impact because of the distance.  Then, when manta get closer, ambient light filter will compensate (cancel) red lens filter and I will get a perfect white manta's belly.  Am I correct? 


This is all theory, at least my understanding of it.   

My camera is Sony A7Rii.

Many thanks.

#387104 Another Lembeh Video

Posted by kc_moses on 30 August 2017 - 05:16 AM

I haven't been able to get the thumbnails to embed for a while now. I used both the youtu.be and youtube.com links.

Am I missing something?

You used the wrong Youtube.com link, the one you provided linked to the edit/play list page. Once you have uploaded your video, go and watch that video, and copy the URL in the address bar. The URL should have Youtube.com/Watch?......

I just paste that URL here and it shows up:

Posted by kc_moses on 28 August 2017 - 05:27 AM

Just a warning, I finally reviewed the video I shot with the LX-100 with the Fantasy UWL-09F WA lens. The corner has some softness issue. So I think if you want to use the UWL-09F, you would still need to zoom the LX100 to 28m-30mm to get rid of the softness. For that price compare to Nauticam WWL-1, it could be a good compromise.

Posted by kc_moses on 25 August 2017 - 05:19 AM

I thought Basil changed camera?! If anyone is shooting with LX100, I recently tried out the Fantasea UWL-09F, it's the best WA lens for the LX100, beat the Nauticam WWL-1 in term of field of view. The LX100 is a 26mm focal length when shoot 4K, so it's very wide combine with the Fantasea wetlens, and give it a semi fisheye look.

#386948 What are my RAW options as at August 2017?

Posted by kc_moses on 24 August 2017 - 05:26 AM

RAW Video is a luxury, that's why there is lack of comment. The interest is there, just that most of us know it's not realistic for the masses at this point (expensive media, large storage, transcode workflow etc.)


Also, I know some Canon 5D/6D shooters have given up for the 5D series, and they had no choice but move to 1DX Mark II. Looks like Canon gets what they want instead of listen to their advance/semi-pro consumer.

If you want to embed Youtube video, use the youtube.com URL, not the youtube.be url (the one that you get from the "Share" button.)



Seems like a great dive that you can get see a lot of big stuffs!

#386421 Color Checker as refrence

Posted by kc_moses on 02 August 2017 - 07:10 AM

I never imply that a new/better gear would make a better artist, I just point out that a lot videographers do not tell people what/how they use their equipment.

#386417 Color Checker as refrence

Posted by kc_moses on 02 August 2017 - 06:07 AM

The editing is the key, if you look at the "Angel of the Deep", at 1:49 and 2:32, any camera can get this kind of shot (DSLR, RED, Point & Shoot), there is nothing special about the color and composition on those specific frame/clip. At the end of the day, it's how you use the clips you shoot, put them together (with the help of appropriate music), and create the right emotion.


A couple years ago I was just obsess about 4K cameras, until recently I just starting to pay attention to use Premiere Pro properly, stop just using fade in fade out transition, try to do complex stuff. I have to say, having more than basic editing skill makes a big difference.

#386414 Ocean Heaven - Socorro Island

Posted by kc_moses on 02 August 2017 - 05:52 AM

Thanks EvilOtter! The top side could be challenging since we never step on dry land. If there is one thing I learn: shoot all bunch of stuffs, tanks, mask, hose, wetsuit etc. When putting the video together, you never know if you need some fillter/transition clip! :D

#386392 Color Checker as refrence

Posted by kc_moses on 01 August 2017 - 10:27 AM

I think it's very common/natural for people to curious about what other accomplished shooter used, and it always come across as the "easy way out". Just like in photography world that people always say "Full frame is best", hence it created this obsession of gear hog and constant camera upgrade.


Personally I don't care about what camera other people use, because I have my own set of budget, I have the GH4 and decide that the LX100 is better for me to use UW because of my budget, and my diving experience is more suitable for a more compact set up. These days I just focus on the quality of content and stuffs that I capture. I come to term that it's better for me to spend the money on more exotic dive trip instead of having nice gear but can't travel anywhere :D
