Without flash for sure but you also have to make sure that no glare gets onto the glass from the surrounding area. Windows & Lights have to be blocked off, best is to shroud the surrounding are with dark blankets. Also ensure that the camera is perpendicular to the glass pane.
You can use flash but not directly on the tank. You may have to take a few pictures to find the "right spot".
Here is one at the NC aquarium where the flash is on my grandson but threw enough light on to the circular tank to get the fish as well. I focused on the fish first to get a lock, then shot to the side so I wouldn't get the reflection of the flash on the glass.
Thanks for the replies. Very nice photo's. I have a 40 gallon long planted tank. I only have neon tetras in it. The back ground and gravel (flourite) is black. It also has 4 light bulbs on it for the plants. I am also having trouble with my reflection showing up in the picture. Do you set it on auto or do you do manual settings?
For any shot through glass you'll have to make sure that it is brighter behind the glass than it is in front of it from where you're taking the shot. The dark gravel you mentioned will be causing problems and will make it very difficult to keep the foreground darker.
- Back light and light above the tank only, complete darkness in front of tank
- Camera on tripod
- Black shroud around the greater area where the camera is located at to avoid reflections that may be created by light colored objects reflecting the light from and around the tank
Nice rylaff, dwarf bi-color angel? hcmcdole, the beam of light gives the feeling of depth, looks like you were underwater with them! I have to push my iso just like you said in order to stop movement. Very nice guys! ☺
Try taking shots at night with the lights OFF in the room you are in but with the Aquarium lights ON. Also try taking the shot from a slight angle. This will help keep light from bouncing back directly at the lens.
