These were shot by (pretty dim) tank light. One 40Watt fluorescent tube over the 55 gal. tank. (That's why I'm in the process of upgrading my lighting). In order to obtain enough light for the photograph, I've set the camera's light sensitivity (ISO) to 1250. This allowed for a barely adequate 1/50th of a second shutter speed with my lens at wide open aperture (F2.8 in the case of the lens I used). I allowed the camera to autofocus on the fish. Autofocus tends to work best via areas of contrast, such as the fish against the plain water and background. You still have to wait them out for a period of little motion...then fire away. You really have to have the advantage of a DSLR to make these camera adjustments along with virutually no "shutter lag". This wouldn't be easy to do with most point and shoot cameras. Hope this helps.

How do you take their pic? No matter what I do I just get a blur because they are so reflective.![]()
