I don't know how to deal with RAW photos...I should learn. I would like to get really good at photographing my tank. :)

Probably just high iso, typical with any compact, if you take slower slots with a tripod you could turn the iso down and probably reduce that quite a bit.

I wouldn't use one of those DicaPac cases except for maybe rain protection, definitely not submersible. Typically you can pick up a used G9 in good shape for $200 or less so check out kijiji or ebay. The Cannon case is only $200 so if you're planning on any diving or snorkeling then it's well worth it but if not then maybe the cheaper alternative is all you need.

:surprise: You had a G9 and didn't use RAW :question: :nono:

Haha, no I didn't know how to process RAW afterwards. :lol:

I thought the Canon waterproof case was $250? I do plan to use it for snorkeling and in my tank. The DicaPac has good reviews...?

i find light room is best for processing raw, especially if you have a whole bunch at a time.

and 250 for a waterproof case is nothing. some dslr underwater housings are over 5 grand

I got mine for $200 so probably depends where you buy it. Good reviews or not it's a ziplock bag with a glass lens attached to it.

Don't talk to me about underwater housing, I have a Sea&Sea D200 housing, with the fisheye dome port, and flat ports, focusing gears, etc
and a Light and Motion D200 housing with the Glass Fisheye dome ports, flat ports, Nikon underwater strobes, Ultralight arms.
Then an undervideo housing with HID lights, etc

That's why I didn't update my D200's, because then I have to buy a new housing at 4K or more. I would love to get a housing for my D700.

I still have an housing for my F100 (film camera), plus you need to service the housing every 3 years or so at a cost of 1K.

One day I may get one of these :)

still waiting for mine

Be careful of Canon waterproof housings. I had one that flooded on my last trip and it was found to be defective. Luckily it was replaced, along with a new camera (S100). After a bit of research, it appears there are issues with the mould lines from production. They don't allow the o-ring to seat properly and allows water to enter. This was my wife's camera and we thought we would go a little cheaper on the housing as it wasn't going to be a secondary camera. Needless to say, we have a new Ikelite housing ($350) arriving any day soon. I've had no problems with my Ikelite for my G11.

As for RAW, if you purchase a new Canon camera, the software that comes with it includes Digital Photo Professional that will handle RAW processing. Easy as pie. I now shoot nothing but RAW when diving. I've got a few pictures in my office that have been enlarged and they look pretty good.
