#382317 Panasonic LUMIX GH5 for underwater video

Posted by ScubaBob on 16 March 2017 - 02:53 PM

Might have my hands on a GH5 (no housing though!) for the weekend. Any tests I should do that haven't been covered by everyone else on YT?

#381368 Panasonic GH4 Settings for Underwater

Posted by ScubaBob on 09 February 2017 - 07:03 AM

Both. In camera I MWB often to keep me close. I probably end up adjusting about 5-10% of my shots in post for color (most adjustments are for shadows/highlights).

#380908 DIY - Make your own fiber optic cable for your underwater flash - works with...

Posted by ScubaBob on 24 January 2017 - 03:29 PM

Do you have link for cable and connectors? I read that the 613 fiber cables from s&s may work with the triggers? Those cables are pretty expensive though.

Thanks for posting your videos! I just completed my quadripod based on your design and really looking forward to using it!

#380682 High ISO Pana GH4 clip to share

Posted by ScubaBob on 16 January 2017 - 02:29 PM

Hi all,

As the title says.
Has someone some original underwater clip from a GH4 shot at high ISO to share?

I mean ISO 1000 or 1250 at least.

 

Thank you in advance

I have quite a bit of high iso footage I can send you. PM me your email address and I will send some via wetransfer. From looking at your previous footage, you tend to shoot primarily wide angle, with video lights on the foreground/subject, correct? You won't get nearly as much noise with this kind of shooting. The background will be much more blue, as it is with the GH3 and GH3, but will be a much cleaner image then trying to shoot with all ambient, or requiring the camera to shift WB across the entire image.

I have the GX85 in the Nauticam housing. Only 2 dives with it so far, but love the camera so far (save for the short battery life). Here's a few pics taken with the camera (first time using strobes in 15 years, so not the best). I will be using the camera primarily for video.

Come on Evan, I think you need another housing. Maybe preorder GH5 housing? :-)

#358024 GH4 - Nauticam Macro Lens/Port Thoughts

Posted by ScubaBob on 18 February 2015 - 01:56 PM

Out of interest seeing that the pz14-42 has focus at start of shot and you can refocus why would you need manual focus? Looks like autofocus works wonder for me

 

Ok, probably a 1000 different scenarios I can think of :) For example, you have focus locked on the eye of blenny, which is perfectly in your lower right power point. The fish moves and the eye is now in the lower left power point, still a great shot. If the gods are on your side and you are in focus tracking mode you may be ok. But they aren't, so you're not and the eye is out of focus. You can either re-establish focus and reframe your shot hoping the blenny doesn't move, or use the manual focus knob slightly and using peaking, get yourself back in business.

btw, it was very interesting how you attache zoom gear on pz 14-42.

I haven't try this lens underwater yet but so far footage looks reasonably sharp and OIS working well.
 

 

Have you tried assigning the electronic zoom to a function key and using the up and down arrows to zoom? I do this and land and it works great (I don't believe the GH2 has this - or at least I haven't found the option). I haven't tried this lens underwater, but thought about doing so using the camera to zoom and building custom gear to engage the manual focus.




#357916 Panasonic GH4 might get a V-log profile?

Posted by ScubaBob on 16 February 2015 - 03:59 PM

Bleh no. I want it as close to accurate as possible out of the camera.

 

Sorry, posted to soon. I do attempt to fix the color if it's not too far off, but I don't think I need a flat profile for that. I think there are too many factors shooting underwater that flat profiles will never help for.

Bet 5c is something like standard or scenery and not anything advanced
White balance looks very accurate not sure if this was custom or presets but very good actually looking at the saturation maybe there is even a filter involved?


You're out a nickel on the profile. It was actually shot in Vivid, which, by the way is a mistake I will never ever ever make again with the GH4. I usually shoot in CineV - which I've loved the results from - but somehow I ended up in Vivid and didn't notice until the end of the day. Vivid is much noisier than CineV, and actually produces a ton of Croma-noise, which I hadn't seen with the GH4 so far. It was noticeable above ISO800 (though 1600 was my max) and with ambient light (though mostly disappears like other noise when down sampling from UHD->1080p. Much of the footage I shot below 60fsw (except for the Purple Hydrocoral at 95fsw which I had lit properly) was unusable.

You are right on the filter - I was using a magenta filter on the 7-14mm for dives 2-3. The close-up and macro stuff was on dive #1 and shot with the 12-50mm - no filter. I manually white balance, far more frequently than I check my SPG :-)
