@lox -- I use a DC1000 Maxx. I was not happy with my pics because things would appear washed out or all green. One of the best things I did was adjust the EV (Exposure Value) to a negative 2 (-2). This gave me the bluer blues that I had been desperately wanting. I also adjusted the LCD display to a negative 1 so the LCD was a) easier to see underwater; b) gave me a more accurate representation of what the camera was "seeing". These tips were given to me by Cathy Church at Beneath the Sea year. Also, set your pixel count to the biggest the camera has. Set your resolution to Super Fine (that's the setting for the 1000). This will give you the most data to work with. Sometimes, the "washed outs" can be fixed in photoshop or other software. Adjust your ISO to 200 and leave it there. Anything much higher will give you wash outs and noise.
I shoot a Canon DSLR uptop but wasn't ready to take the risk of flooding an expensive camera. Since make the adjustments to my SeaLife, I have been much happier with my shots.
The best thing you can do is to read the owner's manual, then start shooting in and out of water. Understand what those settings do. If you are using the auto settings, make sure that the camera knows whether you are shooting in green or blue water. I have gone to using the manual flash setting because I like being able to adjust my shutter speed and aperture.
I personally angled one strobe (when it was on the SeaLife arms) over the lens of the camera. The other strobe was often contorted into all matter of angles.
Hope this helps.
