In this section we will focus more on the camera, and how to get better pictures with it.
6) Reflections. This is all about angles, if you shoot straight into the tank, chances are good, that the flash will reflect back. Thankfully some images may be salvaged by cropping, but don’t rely on this method. Also reflections of the camera and the tanks surroundings can show up in the pictures, effectively ruining it.
7) Focusing effectively. With non SLR cameras or point and shoots with the ability to focus manually focusing on the subject can be a real pain. If it won’t focus on the fish you may make it focus on something else inside the tank, if it focuses correctly on the object you point it at it should appear sharp. Hold the trigger half down and drag it to the fish. Minor adjustments must be made but with a little practice you should get the hang of it. This will not work as well without turning on the cameras flash. If the camera does not focus try putting it on macro, putting more light over the tank or moving back a little. Some cameras focus closer when zoomed in a little bit, especially wide lenses.
8) Motion blur. This may not be a problem when shooting plecos but with some danios and tetras this may be a major setback. One of the hardest things with those fish is even focusing on them! With these fish, if you can’t use a flash you are pretty much sunk. Try to use the fastest shutter speed as possible, with a fairly high ISO and LOTS of light. Moving along with the fish may sometimes work but most often doesn’t. Another trick go to sport mode this is generally faster then normal.
9)Time. Generally I like to take pictures when the room is dark with the tank lights on. This minimizes reflection.
10)Getting the fish out of hiding. Who hasnt at least had some trouble with this one? This is extremely hard with catfish as they refuse to come out except at night. As soon as the lights go out they come alive but if you turn it on they will disappear, similar to certain shrimp… The most obvious method is to find them, tear up the tank to expose them for a few seconds to snap a picture. I have done this many a time out of desperation, only use this as a last resort. For cichlids (especially dominant cichlids) they can sometimes be drawn out by the use of a small mirror. Feeding is often succesful with catfish.
