I used to do a lot of underwater photography using the Nikonos V Camera, and have 2 underwater strobes (Nikon SB102), and a Sunpak Marine Auto 3200. Guide numbers for both of them are 32 (m), both have diffusers which reduces the guide number to 22 (m). Wait for it, because there is a point here regarding this topic. Both of these strobe units have slave capability, and so . . . . could theoretically be triggered wirelessly from my Sony HVL-56AM flash unit on my A100
These strobe units have been packed in a box for a few years now unused (Sunpak is brand new!), but this would give them a new lease of life above water, as 'pseudo home studio' strobe units. Both of them are fairly powerful units, so could provide excellent background lighting. Easy to mount them on tripods for positioning.
I did read one of the posts about A100 pre-flash triggering wireless slaves incorrectly, but would this apply in using the HVL-56AM as the triggering unit? They are both fitted with syncro cables, but are fitted with Nikonos underwater connectors. Time to play around with the concept over the next weekend!
I know Stef uses cheap flash units at times in this way, and has mentioned before that the concept works.
Any thoughts, comments or ideas?
