Canon EOS D30 Opportunity - PICS ADDED

[Snaz]

I will be borrowing a Canon D30 this Friday afternoon with the intention of shooting my corals. I want to make sure I take the best pictures I can the first time as I only have the camera for the one afternoon. Please any tips or techniques appreciated.

I know SLR cameras, how to set ISO, aperture, shutter speed etc and I have a Canon PowerShot that I'm sure I have taken the best possible pictures with.

The 17-85mm lens is not a true macro but it does have a macro setting. I think it is this one:

I will also have a nice tripod and automatic shutter release.

I want to take the best pics of my corals, mostly zoas, rics, shrooms etc. as possible. Thanks
Keith.
