Aquarium Macro DSLR Tips

[MarkoD]

-I'd say use a small aperture to get max depth of field.
-Add light with a flashlight or flash to make shutter speed as high as possible.
-With a 7d you're probably safe to go up to iso1600
-Raw so you can adjust wb later to your liking.
-make sure the lens is parallel to the tank glass and as close as possible to avoid reflections (also turn off as much as of the room lights as you can)
