I used to use a Nikon Coolpix camera. It took awesome closeup shots, but I could not ever get a full tank shot to save my life or any other regular picture even non-reef related. So I switched to the Canon and couldn't be happier.
I use a Nikon coolpix 5700, just got the camera and will post pics when I learn how to use it. :? So far looks like a very nice camera, 8x telephoto and very good Macro from what I've read on the internet. :drinking:
I use a Nikon Coolpix 990. I loved the 880, and when the 990's came out, I couldn't help myself. I have been happy with it, but the Coolpix series does have quite a steep learning curve (oh-so many options).
I just posted some of the pictures from one of my nano's in the nano section
Nikki ... I love my Canon G2 ... G3 would be even nicer I am sure.
I try to take the pictures of fish with a light flash. Very difficult to catch them without a flash in a nice still fashion. I do not get right up to the glass either, a good 6 inches away. The fish can not be swimming toward the back of the tank either, it is best when they are in the first 6 inches or so of the tank.
I try not to use automatic mode. That way I can vary the amount of flash and sometimes the exposure as required.
For coral shots I try not to use the flash. Again, the subject has to be more toward the front than the back to get a good picture.
I do not use auto mode here either ... I try to use most the standard settings with no flash in the macro mode in the P setting.
Believe me, it takes time and practice to get it right
