#397948 Sony RX100 VI - Ultimate P&S camera?

Posted by kc_moses on 30 July 2018 - 05:47 AM

The RV100VI is still over price for what it has to offer compare to my current Panasonic LX100. I would rather wait for the LX200, or even the Black Magic Pocket Cinema 4K before considering the next GH series camera because the GH camera price is getting high. Canon will have better mirrorless coming out soon so consumers will have more choice compare to 2 years ago.




#395826 Ocean Peace at Tiger Beach

Just sharing my latest project:

 

 

Before you make any comment about the diver's interaction, please make sure to read the description in Youtube.

 

If you like sharks, Tiger Beach is definitely one of the destination you need to go!




#394349 Who is excited about Blackmagic Pocket Cinema 4K?

Well, what do you know? The screen on the Black Magic is already tilted to begin with! I think Black Magic really put a lot of thought into this camera:

And look at that screen size! I don't think you really have to be at eye level to look at that screen because of the size, and if you have focus peaking on, you can just look down and see what's in focus easily:

Yes look like a lot of the essential functions have physical buttons. Having Function button would help too. The great thing is it supports speedbooster as well, so you have more option for faster and wider lens. It can be charge through the USB-C, not sure if it can power the camera while it's in use.

 

There is however a concern, that's the fan and the heat:

 

The amazing thing is, this camera basically is the price of the GH4 when it first came out, and this camera offer a hell lot more features than GH4. Time will tell. The funny thing is the "Z Cam E2" basically become way inferior right out of the gate.

12-Bit RAW!!!! 5" screen means no need external monitor. Recording to external SSD through USB-C. Battery life is about 60 minutes, I think it's doable just replace battery on every dive, battery is Canon LP-E6, very cheap. I hope Nauticam will make a housing for it soon. The price of the camera is so reasonable especially you get a full version of Davinci Resolve.




#394107 GH5S Better colour

Posted by kc_moses on 05 April 2018 - 07:32 AM

I have a friend who shoot Canon and he said the GH5S color is pretty nice (he only test drive the GH5S once). So for those who have GH5 and GH5S, you probably need to compare, and color grade them slightly different. I think the GH5S color probably close to the Canon.

 

Skip to 5:50 in the video and go from there (the whole video has lots of useful info as well):




#392506 IS IT WORTH IT? GH5s - No Stabilization

Posted by kc_moses on 19 February 2018 - 06:53 AM

Kristoph,

 

Yes I shoot ambient light in Socorro with Magic Filter. I know it's deep so I need to use custom white balance method to bring out the blue color. Unfortunately the visibility got bad half way into the trip so the white balance was challenging. At 3:30 into the video, you see some light on the Manta, it's a Keldan light from the boat's videographer, he swam around and shine his light everywhere and piss many people off, so watch out for people who abuse high power video light. Since I shoot ambient light, it's hard to swim on top of the Manta to capture the top side view of the manta because everything will be very dark. So it's a tricky experience for me.

 

As for your question of Canon 5DM4, I know 2 very skill videographers who are highly disappointed with it and decided to move to the 1DX M2 since the price is still manageable for them. Besides the file size, the big drawback of the 5DM4 is its crop factor, it's so bad that you can't really shoot good Wide Angle with it. I'm not sure if they corrected the crop factor through firmware update. Also, the 1DX M2 can shoot 4K 60 fps, so it's a highly desire feature with many professional videographers.




#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.

 

 

Here is your answer:

 




#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:




#387046 Diving in Tubbataha

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.
