#383555 Anyone happy with their TriPod?

Posted by ScubaBob on 25 April 2017 - 11:11 AM

I've generally not taken my old tripod setup when I've shot wide (7-14mm On M43), only when I'm shooting macro (60mm) or with my general purpose (12-50mm) lens. I plan to start using my new tripod/quatri-pod setup on every dive now. The telescoping legs are more attractive for this as well..

ScubaBob, can you post a picture of the bottom of your camera/tripod from this TI1976 DIY design? I'm intrigued by this idea...
I did a google search for it and no Luck :( 
 
Thanks,

Sure thing, see below. Here's a link to the video:

The xit tripods seem like a great way to go. I almost went that route until I stumbled upon TI1976's DIY design. I replicated that design fairly closely and love the results. 843851624bdf9ad44fd3ee1913b8b1ab.jpg67fe93c78aef8a3563c545a2fe2b896f.jpg

#383017 Nauticam dealers now list part 17713 for NA-GH5

Posted by ScubaBob on 10 April 2017 - 08:25 AM

I'll try to test this when I get my hands on the camera and housing. I have mostly moved away from auto focus, but have had some success with some of the GH4 tracking modes. It does become one more thing to keep track of when shooting in full manual mode, but when focus is messed up I know it's my fault for not setting it right, not the cameras fault for deciding to focus on some algae rather then the rhinophores I originally focused on.

I find auto-focus, using back button focus, is "good enough" to get close and then I can adjust as needed (using manual focus knob if available, or by moving camera). Nauticam's addition of the large back button focus control on the GH4 housing was genius - and I really wish they had it on the GX85 housing. I was happy to see that it's been retained on the NA-GH5 housing.

Auto focus becomes increasingly challenging as you 1) reduce your depth of field, 2) increase the resolution and 3) switch to larger sensor cameras (related to #1 above). Small sensor dedicated video cameras are better at autofocus and keeping your subject in the "sweet spot". With the 60mm macro lens wide open your depth of field is 1-3cm at best. Shooting with the 7-14mm you obviously have a little more breathing room - but cameras AF modes still seem to "zone out" on the blue water occasionally.

Thanks for letting me ramble..

#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).

#381091 Panasonic GH4 Settings for Underwater

Posted by ScubaBob on 30 January 2017 - 06:30 PM

I've only tried the white balance card approach a couple times but never like it. I've always performed a manual white balance on or near the scene I'm shooting. The GH4 handles this well. Here's an article I wrote on some of my favorite GH4 settings:

#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? :-)
