How can I eliminate the amount of backscatter in this picture? I only have one strobe right now. Would the use of two strobes help with this?

Not being an expert and not knowing where/how your strobe is positioned I would probably suggest moving the strobe further away from your camera and possibly angle it out a bit. I am sure someone else will have further suggestions.

You might get more response here if you posted the photo in this thread so people don't have to click away. It looks pretty silty on your dive. Changing the angle, power and distance of your strobe will help to a certain degree, but after that you just need cleaner water. You could try getting closer to your subject to eliminate the amount of silt between you and it.

Hello Sean,

Having two strobes can actually increase the potential for backscatter, especially when you're shooting near the sand like you were at SBI. Honestly, it looks to me more like there's just a lot of particulate in the water, than pure backscatter. However, angling your strobes "out" a bit more, and behind your dome port would help. Also, when you're in an area of high potential for backscatter, try to compose your wide-angle shot with more reef than open water. The reef really helps to hide the unwanted backscatter.

Here's an article I think you will find helpful ---> http://www.uwphotogr...tter-underwater

There's an excellent tutorial on how to remove backscatter from photo's in Alex Mustard's site. See http://www.amustard....=...news&size=s

Here is a link to an article from Alert Diver Online by Eddie Tapp.

It's a really easy technique that takes a minute or so once you get use to it.
Hope this helps,
