In Topic: Advice on How to get Close

For wide angle, don't breath a lot, don't move much, and never chase a subject. If you chase, all you get is fish buts. I can send you plenty of photos of those.

Never act like you are hunting your subject. They will pick up on that behavior.

For macro, get the longest lens your water clarity will allow if you are shooting skittish subjects.

If it fits, that would be close to first in the history of UW photography.

In Topic: Vacuum leak detector question

23 March 2014 - 01:45 PM

I had one on a Nikonos V, the pressure did help prevent leaks. Seats the O rings and applied pressure to them.

The Nic V had a problem with the 15 mm lens on the surface. The lens had some wiggle in it and could leak at the surface. At depth it was fine as the lens was pushed against the O rings. The vacuum eliminated this problem.

On the negative side, the alarm would sometimes go off and you could not fine a problem. It seemed there could be a gradual loss of pressure that would set off the alarm, but not be enough to actually cause a leak.

I ordered one for a GX 7 housing.

As an eye doctor I've taken graduate level courses in physiologic optics.

Nocturnal species are very sensitive to light, diurnal mostly not.

What are Sea horses primarily?

All species regenerate their retinas, that's how you see.
