Thanks, Tom.Tom said:For my full tank shots I use my tripod, have the camera in AV mode with the aperture between 4 and 8 dependant on light. Then I set it on the timer and leave it to take it. I use manual focus and set it to something like a rock thats roughly in the midground. They came out pretty good that way. But I was using an "L" lens so that may have helped with sharpness.
