Have just taken some photos with my camera in Macro mode and also ISO 400 and the results are much better. Flash off aswell. I also have a tripod. Just a matter of time i think now as the fish dont like staying still for long, haha.
Alot of my fish seem attracted to the camera, especially my Firemouth's, which is great as they are one of the fish i am trying to photograph. Unfortunately the other fish i really want photos of are very camera shy. They never hide when i approach the tank but as soon as the camera is out......whoooooosh..........gone. HAHA They are Golden Severums, the large one looks beautiful and would be great to have some nice photos of them.
Time and patience i feel. Thanks so much for your advice, you have made a difference already. Any more suggestions are gratefully received.
p.s. Guess there is one thing you cant get round though......scratches on the glass. My tank was given to me by a friend who had recently moved (3 years ago) and i believe in the move it got scratched. Not enough to worry about but they really show up on the photos
