Hi,
I've been diving since 2009, and I've always brought a camera with me (I'm a photography enthusiast on land
). I already own a Canon G10 and use a WP DC 28 housing, and I've already decided UW photography is something I want to keep doing, but at the same time, I don't think I can "invest" more into it right now. Had I known I'd be loving it a lot, I would've gotten a better housing - haha!
That said, I'm also considering upgrading my set up to include strobes. I've received suggestions to go for 2 small strobes, and I'm interested to find out what the recommendations are. I don't think I'll be changing housings anytime soon so I'm stuck with the WP DC 28 -- are there filters available for this already?
Sharing a link to a few of my favorites... photos are edited with Lightroom but mostly just contrast, a touch of vignetting, and doing my best to get rid of the blue-green tint when shooting without filter...
