Low Visibility Shooting - Mustard video interview

27 May 2015 - 12:41 AM

I was in the Netherlands at the weekend for the CMAS World Championship of Underwater Photography. It is an excellent event, which was first held in the 1970s and has travelled all around the world in the intervening years. 

 

I was really pleased to see it come to the Netherlands, particularly because the low visibility conditions would be a stern challenge - rewarding the photographers who really know what they are doing. Although the images won't be as amazing as in easier conditions, the competitors produced some exceptional work, especially considering every shot must be presented straight from the camera - no backscatter removal allowed! Each competitor was limited to just 4 dives to produce images in 5 categories.

Anyway, below is a video clip of an interview I made during the event, with my dog Zena hanging on my every word as usual...

 

The first half of the interview is about the competition judging, the second half of the interview (start at 02:17) is about my approach for shooting in low visibility conditions:

Will Nikon D7200 fit straight in D7100 housings

02 March 2015 - 01:21 AM

Thought I'd start this discussion!

 

The D7200 looks very, very similar to the D7100. These two photos come from the Nikon website:

Maybe this will slot straight into D7100 housings. I know a some housing manufacturers were annoyed that the Canon 5DS fitted into 5D3 housings - meaning no sales for them and also for the manufacturers who are fast to market - no early sales boom over other brands. 

 

Might the D7200 be the same?

 

As a D7100 housing owner, I am particularly interested. Especially as I only have one D7100 body and nearly bought a second earlier in the year.

Full Frame SLR wide angle corrector port tests

20 December 2014 - 02:54 PM

I have just begun experimenting with an optical corrector port for wide angle underwater photography. My intention is to use it on my full frame SLR to give me improved image quality - especially corner sharpness when using non-fisheye wide angle lenses. The corrector was build by Carl Zeiss and adapted for my housing by Pete Ladell. 

 

Here it is on my Subal ND4S housing:

I thought I’d start a thread to present and share my findings as I go along.

 

In theory the adaptor is afocal and can be used to correct any lens that will fit behind it, which is an enticing prospect to be able to use many different lenses underwater, including zooms, with theoretically a much better correction than a dome port. Basically turning any lens into a corrected underwater lens. Autofocus and everything else working as normal.

 

Of course, that is just the theory. I took it to the pool yesterday to try it underwater. I am not necessarily the biggest fan on pool tests and much prefer to evaluate optics with real world subjects. But this was a massive step into the unknown - so the first aims were to check that it didn’t leak and to check it even worked at all. This corrector was designed for a camera without a viewfinder - so nobody had ever looked through it before underwater! 

 

Hooray, it seems to be keeping the water out - test shots of tiles:

The small port size offers possibilities for CFWA:

And yes, it works, the photo I was taking, above:
