#328882 New Housing "Airlock" Vacuum from Backscatter

Posted by John Bantin on 31 March 2013 - 01:28 AM

I know of someone who did forget to pull a vacuum and went in the water without the plug. This is essentially like diving with a hole in the bulkhead of your housing. Fortunately, he had a dome port on and caught it as the water started rushing in so he was able to turn the camera so the water began collecting in the dome as he was aborting the dive.

To Adam's point, having a vacuum system isn't completely fool proof. You still need to check your system before jumping in.

This doesn't add up. Surely, if water could get in, air would have got in first, before he hit the water. Sounds like someone ignoring the red light. Thank goodness he doesn't have a rebreather!

#328866 Planned ban of underwater cameras in Sipadan

While I abhor anyone trashing the environment just as much as I abhorred tourists chipping away bricks from the 1000-year-old White Tower of the Tower of London as they did in the '50s, the fact of the matter is that these things are much more complex than a simple solution would suggest. For example, we in the West have fuelled the shark-finning industry by buying cheap goods from those countries that want the end-product, enriching them and pushing up the price, thereby making shark fins so much more valuable. We are ALL to blame. Modern industrial society in which we live and benefit brings with it many negatives.

Part of the problem has always been the reluctance of Asian dive guides to remonstrate with Western guests. It is a cultural thing.

Stephen, It was a pilot trip put together by Stuart. I'm surprised you weren't there! He'll be doing more next season, I'm sure. In one month the feature will be archived on www.divernet.com but there is a (free?) Diver Mag app. for iPad and Android that allows you to see current mags although you have to pay a few dollars for each issue. This issue on the app includes some extra pictures pictures (I actually shot 2146 usable pics!) and Fraziers short-version video.

#328744 D800 to Ipad?

Posted by John Bantin on 28 March 2013 - 02:58 AM

Thanks for all the info. I settled on the small Macbook Pro. It does everything I need and it fits in my back pocket of my photographer's jacket (for carry-on purposes!).

#328322 Simplify your life!

Posted by John Bantin on 21 March 2013 - 10:50 PM

Over the years I have collected more photography gear for use underwater than any man would ever need. Recently I have been selling off all the kit I really no longer need. Apart from the film stuff that I actually gave away, I sold all that perfectly good equipment that I was no longer using. I am now down to one housing, a set of ports, two camera bodies and two lenses (for underwater use). I kept a range of lenses for surface and studio use. I recommend it. The feeling that comes with simplification is wonderful.

#328319 Tokina 10-17 for sharks. mini dome or 8"?

Posted by John Bantin on 21 March 2013 - 09:14 PM

For DX the Tokina 10-17 would be my favourite lens. Nowadays I use the Sigma 15 on FX. You gotta hold your nerve and "wait until you see the whites of their eyes".

#327992 Tripods

I once had a gyroscope that mounted on the bottom of my (still) camera to give a Steadycam effect. I wonder it it would be possible to get one housed and fitted under a camera housing?

There's a riot of Great Hammerhead pictures in the April edition of Diver Magazine UK. (an unashamed advertisement   :)  )

#327789 An Epic Week

Posted by John Bantin on 13 March 2013 - 12:03 PM

Two weeks ago I was on a boat as one of four DSLR shooters but out-numbered by SEVEN Epic users with five Gates and two other housings. There was also a 3D video set-up. Is this a record?

#327634 New Housing "Airlock" Vacuum from Backscatter

Posted by John Bantin on 11 March 2013 - 12:01 AM

Please explain your insinuation John



You implied that because Hugyfot had taken a quote by me from Diver Magazine, my support for vacuum pump systems in housings might have been disingenuous. I get no remuneration from Hugyfot or Wetpixel or any other industry members apart from the magazines that pay me for me impartiality, which I vigorously defend.

Sounds like you need to try each. It's a personal decision.

#327411 I don't get it!

Posted by John Bantin on 07 March 2013 - 06:45 AM

If you use a longer focal length lens, what are you doing if you are not cropping in camera? You simply use a smaller part of the image circle for a given size sensor. As I have said before, optically speaking, it is the quality of the water that has most effect. The more water between the lens and the subject, the poorer the quality of a given shot.
