Kirk, thanks a lot for the response, those links are very helpful. If you don't mind me asking, how long have you been shooting underwate rwith point and shoot before you decided to move to DSLR? I've taken probably close to 1000 photos underwater with P&S and am very dissatisfied with the level of detail in the image.
1st let me say, I haven't moved to dSLR yet! I think we are both at the same point, but since moving to dSLR is a huge investment, I'm looking at every potential cost (i.e. lenses, housings, ports, domes, port body, extension, zome gears), which can really add up.
to answer you questions, I have been using the point and shoot for 2 years, including trips to the Florida Keys, Curacao, Roatan, North Carolina, and The Great Lakes. I typically do 1-2 reef trips a year and take more wreck trips. If I were to guess, I've taken 2-3K pictures, keeping roughly half. I do use photoshop Elements 6.0 which can spruce up some of the colors you may be having problems with.
What I have found is that I would like to have control over the Apeture, shutter speed, and high ISO to get better pictures in tricky lighting conditions. I also see that there is a role for RAW photos since I use PSE. Since I wanted better pictures, I started getting underwater photo books. For B-Day this past May, I got "The Art of Underwater Photograpy" book by Abdrea and Antonella Ferrari. It's a descent book that I enjoyed, but what I really liked was the way it was laid out. It has several pictures with info such as Camera, housing strobe, and lense. This kind of gave me what kind of equipment I may need to get good pics. I didn't know until I read the book that to get the half above and galf below the water youy needed a Fisheye lense. I'd attemtped unsuccefully with the P&S wide angle lense with no luck. I also noticed that with the fisheye lense, that you had to get right on top of things to get the pics with good results.
I received last week The Underwater Photograper 3rd ed by Martin Edge. If you don't have it, I would HIGHLY recommend that you read it and review the posts here befpre making the plunge (I know I am). This is a pretty big investment as far as money goes for me.
Since I don;t have ANY experience with dSLR, I depending on the members on Wetpixel for their thoughts on this camera.
