Perhaps there is something unusual about British divers that causes the fatality, but in reality, a rapid ascent is a manageable event... as long as there is no pulmonary restriction.

 

Unusual? The British Sub-Aqua Club has long cooperated with the police, hospitals and decompression chambers to investigate diving deaths in the UK, if that's unusual. One thing that became clear many years ago is that there's a world of difference between a planned rapid ascent in training and one made in an emergency, particularly if there is a regulator failure or, heaven forbid, an out-of-air situation. I think that you're dangerously sanguine: how many burst lungs are too many? I also think it's silly to distinguish between the rapid ascent and failure to exhale: they are, of course, two sides of the same coin.


In Topic: A week Raja Ampat with GH4 (stills)

Heading to Raja Ampat in May seems to be plenty to take photos of.  Is the 4.33" dome port the nauticam port ? I have the 8mm fisheye lens and tossing up whether to go for the Nauticam 4.33" or the Athena 100mm glass dome port. Any thoughts ?

 

Raja Ampat is marvellous: here are some images from December.

 

I'd recommend a small dome, except for the split level shots: lighting the sea fans and corals is much easier with a small dome (I'm not sure that there's much difference between different small domes). I was using a big Nauticam dome with a full-frame DSLR and there were shots that I just couldn't get.

The Sigma 15mm is probably the top performer. The Nikon 16-35 is OK, but needs a really bulky port and extension to work well, and it's a bit tight.

 

Most of these images are shot with a Sigma 15mm.

It's always too difficult, so, as usual, I'll cheat. One from Truk, one from the Red Sea and one from Raja Ampat:

I love the bait fish schools, but then I’m partial to that kind of thing!

 

 

They're missing something. I can't quite put my finger on it...
