Hey folks, looking for a bit of insight. I’m shooting with an Olympus E-M10 Mark IV in a Backscatter Octo housing, using dual Sea & Sea YS-D3 Duo strobes. I usually stick with RC mode, which limits me to a max shutter speed of 1/160 sec. That’s generally fine, but in bright conditions with clear water, I sometimes want to bump up the shutter speed to darken the ambient light and get a nicer, deeper blue background. Would HSS (Super FP mode) be a good option here? I know I could switch the strobes to manual, but I’d rather keep using RC if possible. Anyone tried this setup or have thoughts on how well HSS works underwater with this gear?

Hello there. I have been diving since 1978 and doing various kinds of photography since then. My wife and I took a 20-year hiatus from diving due to the normal things, kids, work, etc. We've been diving again since 2018 and have become more and more addicted to it. Simultaneously, I have done more and more underwater photography. I am still quite an amateur but improving quickly as I learn.
