#356667 Sony A7s 4k with Atomos Shogun in a prototype housing

Posted by Oceanshutter on 16 January 2015 - 09:16 AM

" I've heard that it isn't good...."

 

I guess you have to define "isn't good" . If you mean consistancy then no.  If you mean the the Sony sensor is not providing good colour then that is not true. This is one sensor from Sony that is good for UW. The low light ability and full sensor readout definitely played a part. On the other hand It is difficult to get consistent UW back ground colour. Any UW video camera for that matter. Especially when combined with video lights.

 

I have used the A7s for two trips now. For ambient light at the shallows with out video light AWB works. MWB also works well.

 

If you follow Peter's thread he did a sterling job with some UW light filters and the MBW will at least be more consistant with back ground colour:

I am hoping to get a prototype or full production housing for the Shogun. From top side tests this combo is really nice. You could practically shoot in total darkness with a lit match and the scene is still looked okay. Not many Camcorder or DSLR can do that like A7s yet.

 

Cheers

Thanks David.  I will be curious to see how the WB compares specifically to Canon.  Which imo is pretty good at the MWB.  It really is a shame.  The Sony A7s looks to be a good camera, and with the shogun, eliminates the issue of internal 4k recording.  I could live with the metabones adaptor to use the Canon glass I have.  But the MWB is kind of a show stopper, as I am not a fan of wide angle with lights (if not needed).

 

How is the blue water banding on it?

 

I would like to stick with Canon, but they are not moving at the speed that I would like.  A 1DC like dslr should have been released by now, and if there was one in the $3k range, I would buy one tomorrow.  Rumors for a 4k from canon are out there....but you never know with them trying to protect their cinema line.  I also like the full frame sensor.  Which is why the sony is disappointing.

 

Which brings me to the GH4.  Which looks like a capable camera, but I am still not sold on it.  The video I have seen has been nice, but I wouldn't say it is better than what my old 5dII produces....I still prefer the looks of the canon.  Heck, I think some canon footage looks better than RED footage.  Of course alot has to do with post color grading etc...

Ha ha, now you got me curios, what sound would sea cucumber pooping like, squeaky, fart-y, popping...... I once saw a fish poop in mid air and the next fish went behind and eat up the poop...... makes me wonder if marine life are conscious about hygiene........ alright, I think too much :crazy:

 

Oh, one last thing, how do you know when the sea cucumber is going to poop? It's not like it has some sort of expression to make (do they?) I think one of my videos lack is capturing unique/interesting behavior, and your videos have lots of them. It's hard to know and anticipate when they're going to do something or strike for food. My videos are mostly staring contest with fish before either one of us swim away. Being diving in a group (as small as 2 people per group), I can't just sit there and wait for things to happen most of the time because there are other divers behind me waiting to take photos.

 

I was referring to my sounds, laughing and cheering...not the sea cucumbers...lol.  As for this shot, I actually caught it mid-poop.  So I was a quick 15 second ordeal.  Based on the poop that was below him, it appeared it was having a cleansing situation...

 

Behavior is very hard.  And I'm not great at it either.  Although, typically with macro shooting, I don't have an issue with having other divers around.  Typically I let the photographers, normally my wife take the pictures first and then I do my thing.  Places like Anilao, PNG or lembeh, we normailly have small groups, or even hire a private guide in some cases.   For Macro, the guide is there to find critters, not babysit.  I expect the same situation when I goto Bali in Sept.

 

Sometimes behavior I catch, I don't even see it until I review the video on the laptop.  I try to leave the record on for a while, so that all the shakes from the camera and lights stop so that there isn't any movement in the camera.  So that bodes well for capturing behavior as well.  

 

The Kalinga Ornata Nudibranch eating the brittle stars that I captured, again, didn't even see it until I viewed it after the fact.  In that case, I was behind the camera a few feet with a much brighter light trying to attract all the sea lice away from my shot....lol.  I hate that crap!

 

In PNG I was with a mantis shrimp that had a big clutch of eggs, and I stayed with it quiet a while, it was only 15 feet deep.  And eventually it started aerating his eggs.  Pretty fascinating, and I got killer video of it.  Stay tuned for 'Rolling in the Deep - Eastern Papua'!   ;)

Yes, Pontohi it is! Another nice shot. You weren't chasing it around, were ya??


I doubt she chased it. My wife isn't like that. Based on my experience filming them, they tended to jump from spot to spot, normally within a 12 inch radius. A lot of time they are in pairs, and when one leaves the other typically follows.

Dustin, that is a stunning photo!! Your wife should be very proud!

 

I am amazed that the Severins is in PNG. It is great discovering that. I have spent many months, over the years, in PNG and I am obviously still learning a lot about that country.

 

Hey Allison, Here is another picture from our trip to Milne Bay....I think this is the Pontohi...Seahorse you were referring to.  http://www.oceanshut...154455#h9154455

Looks like Milne Bay has quite a few pygmy species!

Fabulous, as always!

 

That Pygmy seahorse looks like a Severens! I didn't know that they were in Milne Bay. It doesn't look like a Pontohi, to me. The only place I've seen Severens is in Fiji.

 

I think you are right Allison.  It looks like a Severens to me as well.  The guides there just called it the Milne Bay Pygmy..lol.  They were all over the place.  Of course, I couldn't find any myself, but the guides showed us probably 50 during our stay.  Very pretty species, although their background isn't as pretty as the traditional sea fan.

 

Here's a pic, my wife took..

Hello everyone,

 

I wanted to share my latest episode in the 'Rolling in the Deep' series.  This time taking a look at the critters in Milne Bay.  PNG is a terrific destination, and Milne Bay is an area where it can offer both fantastic macro and wide angle photography.

 

As always comments are welcome.  Let me know what you liked and didn't.

 

Enjoy!

#354560 Emperor Shrimp

Posted by Oceanshutter on 22 November 2014 - 09:14 AM

Hello Everyone,

 

Wanted to share my latest underwater short video.  I finally got some good footage of some emperor shrimp while I was in PNG.  They are known to be fast and elusive to the videographer.  So it was nice to have some cooperate.  

 

As always, comments and constructive criticism, are certainly welcome.

Enjoy!

Congrats on finishing a project the size and scope of this. Very nice work Nick.


#353595 Nudibranchs of PNG

Posted by Oceanshutter on 22 October 2014 - 02:36 PM

Hello everyone,

 

I know nudibranchs are not everyone's cup of tea.  But they really are beautiful animals especially when viewed up close.  I tried to isolate them with lighting as much as possible to focus on the animal and the amazing colors and textures they have.  I hope you enjoy it.  

 

As always, comments and constructive criticism is always welcome.  Always trying to improve.

 

Thanks again,

Dustin

Posted by Oceanshutter on 19 September 2014 - 08:11 AM

Hello everyone,

 

I wanted to share my first video from our trip to Papua New Guinea.  We stayed at Tawali and had the entire resort to ourselves for 12 days!  it was really a fantastic spot and we really enjoyed both the diving and resort very much.  While PNG is not exactly easy to get to, it should be on everyone's bucket list.  

 

This is the first of a few videos that I will be making from the trip.  Let me know what you think.  I hope you enjoy it!

#351355 Malaria

Posted by Oceanshutter on 09 August 2014 - 08:46 AM

Dustin,

 

All drugs have some side-effects, and based on my experience, Malarone is the best. The 3 drugs that I've been prescribed for diving in malaria zones  are: Malarone, Doxycycline, and Lariam. 

 

Doxycycline increases sun-sensitivity, and while I've used it, it was a bad choice while on the equator and constantly exposed to intense water reflection and sun. None of my dive group uses it.

 

Lariam is known to cause neurological and psycholgical symptoms in some people, and as of last year, carries a 'black box' warning from the FDA. Most of us had mood swings on Lariam, some found it unpleasant.

 

Malarone has been known to cause vivid dreams in some people, but when I do a live aboard, those that are taking anti-malarial drugs are always using Malarone, and no one complains about it.

 

Hope this helps,

 

Cameron

Good Info Cameron.  I am wondering if just keeping up on the sunscreen would be okay with the doxycycline?




#350661 Komodo - Macro

Posted by Oceanshutter on 22 July 2014 - 10:21 AM

Hello Everyone,

 

I wanted to share my latest video I have put together for my 'Rolling in the Deep' Series.  This time it focuses on Macro subjects found in Komodo.  I look shooting macro, and I don't feel that macro gets enough attention at least from the video side.  Some of the coolest underwater characters are of the small variety.

 

As alway, comments good bad or indifferent are always appreciated.

 

Enjoy!

Dustin

#350007 Komodo - Rolling in the Deep

Posted by Oceanshutter on 08 July 2014 - 07:10 AM

Thanks Dustin. I'm going to Anilao next year so I will need similar set up. If it's like Lembeh, then finding a spot to rest the tripod shouldn't be that difficult. I'm thinking of leaving my camera about 2 lb negative, you think that's enough to anchor the tripod?


That should be enough. Anilao is similar to Lembeh. Although some sites do have some coral. In Komodo, doing the tripod on the coral sites is much more difficult.
