#358476 Chariot of Fire - Fire Urchins with Coleman Shrimps, Zebra Crabs & Urchin...

Posted by Nick Hope on 03 March 2015 - 06:02 AM

Not quite sure what happened here... Wanted to try something different and it turned into this pompous piece.

Coleman shrimps (Periclimenes colemani), urchin shrimps (Allopontonia brockii), and zebra crabs (Zebrida adamsii) live and travel on fire urchins (Asthenosoma varium) in Anilao, Philippines.

 

Shot with my Panasonic GH4 in a Nauticam NA-GH4 housing. I used an Olympus M.Zuiko ED 12-50mm f3.5-6.3 EZ lens and 60mm f2.8 macro lens.

Err... feedback welcome... I think... :unsure:




#358036 GH4 - Nauticam Macro Lens/Port Thoughts

Posted by Nick Hope on 18 February 2015 - 09:17 PM

Hmm... I wonder if I can assign buttons to do the zoom on my Olympus 12-50 and do a similar mod to change the zoom knob to a focus knob... In any case I'm interested in this mod and it could be enough to make me switch lenses to the PZ 14-42.

In my experience so far auto focus for macro has been an irritating, inaccurate workaround that has resulted in half of my footage making a quick exit to the recycle bin. I'm confident a manual focus knob will help hugely. But I need to review how I'm doing my auto focus. How are you guys doing it exactly?

By the way, I've ordered the Dive and See 7" monitor.

Very rough test with the Olympus 60mm macro in the housing in air. Minimum size to fill the frame:

60mm only: 13mm subject at 5cm distance
Subsee +5: 10mm subject at 2.5cm distance
Subsee +10: 9mm subject at 1.5cm distance
Subsee +5 and +10: 10mm at whatever range (working distance just 0 to 3cm)

Personal Conclusion: Worth taking the Subsee +10 alone for a bit more magnification (about 30%), but not really the +5.

Basically wet diopters seem of more value for non-macro lenses.

Remember that lighting becomes an issue when you get this close.

I'm not a good enough physicist to know how relevant this test was to performance underwater.

Would love some comparisons with the Nauticam SMC, CMC and the Aquako +15.

I've noticed more muffled swearing on my GH4 footage than my Sony Z1 footage.

Thanks EunJae. The DP4 seems a little small. A DP7 housing would be nice, but I haven't heard of anyone developing one. The Nauticam NA-058 for the TVLogic 058 (5.5") is very interesting but there there is almost nothing about it on the net. I might end up being the guinea pig.

Stupid question: Does the information on the GH4's display also get shown on the external monitor's display? Or does this depend on some GH4 menu setting? If nothing else I need the yellow focus box for focussing.

By the way I finished up pretty happy with the Oly 12-50 and used it for most dives on my Anilao trip. Didn't bother taking my Subsees with it as quick topside tests showed they didn't add much. I did take the +10 with the Oly 60mm.

There was a firmware update to version 1.1 for the Olympus 60mm macro in September. "MF shooting operations have been improved." Might be worth trying for those having trouble.




#355033 GH4 - Nauticam Macro Lens/Port Thoughts

Posted by Nick Hope on 04 December 2014 - 09:07 PM

Having seen a Shogun prototype at Photo Fair in Bangkok, and the pictures of the prototype Nauticam housing on the net, I sent this list of suggestions to Nauticam:

 

1. It would be great if you could include a hydrophone (underwater microphone) in the housing, as the Shogun can record balanced audio as well as video.

 

2. I wondered if it would be realistic to include a vacuum leak-alert system. USD2000 is a lot to lose in a flood!

 

3. Will you be supporting the dual hard drive caddy, which is fatter than the single one?

 

4. I would be interested to know what maximum size of battery you plan to support.

 

5. If you are making a "cheese plate" bracket to mount the Shogun housing with a GH4 housing, if possible please include mounting points so we can add 3 Xit404 tripod legs.

 

6. It would be wonderful if the bracket allows the Shogun to move vertically up and down, or swing up out of the way so we can see the camera.

 

Of course I realize some of these options would add significant size and expense so they may not be feasible.

Thanks Mike :) ... Not quite full time 7 years but did spend a good year on it, all told.

 

SwiftFF5, I'm working on the DVD right now. It will be available through CreateSpace. I'll come back and report when it's ready.

 

I'm also thinking of a Blu-ray too, but really want to find a distributor rather than burn/print/send/bill by myself. Anyone know one?

Davide, I was also shocked with the amount of stuff I managed to shoot in 9 days, but such is the density and variety of life there. 3 or 4 x 90 minute dives per day and excellent guiding helped. No idea when I'll get back. Just getting wet again anywere will be a start. It's been a long time.

 

Here's part 18 which features nudibranchs, sea slugs that have lost their protective shell, but compensate with more advanced weapons of defence.

Part 13, which features a young panther grouper, and then a variety of benthic fishes: stargazers, flounders and flatheads.

Sorry to fall behind. Here is part 12, which features Lembeh's boxfishes, puffers & porcupinefishes.

 




#349363 Hairy frog fish right ???

Posted by Nick Hope on 23 June 2014 - 02:20 AM

Pretty certain this is a striated (hairy) frogfish. Their lure looks correct (like a polychaete worm). You can see another black one with a bit of commentary just after 4:15 in my video.

White Balancing was done very easily using the sequence: WB Button, UP Button and then Shutter, while pointing at a Amphibico White Balance slate. It never gave me any issues from 3m to 20m. Really fast, accurate and no problems. Can't see it needing that slate - Im sure it will work with any - it won't be for a couple of weeks, but I my old PADI Photography slate somewhere - I can do some comparisons for you - if you can wait :)

 

Try white balancing on the palm of your hand. Is that possible with your rig? You might be surprised. Check out the tests I did in 2007 with my Sony Z1.

 

Also, I find your graded footage rather red. Personally I would make it less red and more blue. But of course this is personal preference.
