So I've been doing ok with my Sony RX100IV, Fantasea housing, no strobe, no wide angle, modest expectations and letting the camera do most of the work.
This year for a trip to BVI I wanted to step it up, so I added the Fantasea UWL-400F wide angle lens and the Sea&Sea YS-03 TTL strobe. Studied up on concepts, settings, etc.
My pics weren't nearly as good this year, frankly not unexpected though, as I felt rushed, to get a good shot before my subject's movement makes it impossible and for not wanting to linger too long to take multiple shots with different settings. I also was very unsure about how to position the strobe for each shot, and felt rushed in that regard too.
Since my photographic interest is in marine life (as opposed to, say, corals), and with everything always moving, including the people I'm with and don't know very well....I'd love to hear some thoughts and suggestions on improving as an UW photographer in these generalized vacation-diving settings where you may be the only one on the dive with a camera and strong interest in quality photos.
Thanks,
Howard
