In Topic: Velvia 50 fast enough with a single strobe?

Should be fine - partic as you are not planning to light the entire shot with this strobe.  There will be plenty of ambient light about which you should use.


In Topic: Nikonos V w/15mm

Hi Bakeapple,

 

From years ago the opinion was that the bigger the port the better your chances of success.  Lots of reasons for this and even some of them I understood.  Firstly the "waterline" is MUCH easier to manage and get in the right spot with a larger dome.  The consensus was that it was impossible with a 15mm type dome. I think this reason is convincing.  

 

Second reason I understand less - something to do with focus ability of wides.  The upshot was that you should use a 16mm and this is all I have tried it with.

 

However the other side of the coin is "How many decent shots do you want?"  I assume you are not planning to make a living out of it so try a couple of rolls and see if you get lucky.  The water will need to be glass flat to maximise chances.

 

Good luck
