Greetings everyone. We have started this forum thread to invite you to post general interest questions on underwater photography and videography. (If you have a question specific to your situation, this might not be the place for it.)
If you think SingleDivers.com users in general would be interested in the answer(s) to your questions(s), then please ask them here.
The time to ask questions is as soon as you book your dive trip with Single Divers. Don't wait until the last minute (week or month). Whether you just want 'memories' of your dive trip or your goal is to shoot that magazine cover photo, SingleDivers.com will have you diving in the right place, so you should be ready with the knowledge and equipment. When you travel to remote dive locations you may find that spare parts or accessories may not be available.
So who is going to be first?

As the world record holder for photos of fish butts and my index finger I had a question.
How do you minimize backscatter from particles in the water when your flash goes off?

No Pro here but you need to use external strobe source, not that little baby bit into the point and shoot. Extend arms out and above and behind camera. 2nd place holder on fish butts, that why I shoot video at least they may turn around!!!

Sha,
To add to and expand on what Scubaski said, backscatter is a result of the strobe illuminating any particles between the lens and the subject - the closer the strobe is to the lens the more backscatter you will typically see. You will see a dramatic improvement simply by adding an external strobe to your camera. At this point aiming the strobe becomes critical as an improperly aimed strobe can still give you backscatter in your photos. The key is to aim the strobe so that it illuminates the subject but not the space between the subject and lens. As you imagine this practice can be tricky and you potentially need to reposition the strobe for every shot.
There are some strobes that have a targeting light built into the body of the strobe that makes aiming much easier, but these strobes tend to be high-end models (translation: pricey).
Hope this helps,
Mark

"When you shoot underwater, you have limited time, subject matter that rarely sits still, let alone cooperates, and exposure that changes moment to moment. It's a place where you have to constantly wrangle light, composition, subject and depth, and then find a way to be creative." - Eric Cheng
