Aquarium and underwater photography differ from ordinary pet and animal photography in several different regards. When photographing an aquarium from outside you must for instance avoid reflections in the glass, while underwater photography forces the photographer to find various ways of handling how light acts underwater. The fact that water is harder for light to penetrate than air must also be taken into account when taking aquarium pictures from the outside and if you have a deep aquarium you may wish to consider additional lighting. A 60 centimetre deep aquarium can need twice as much light as a 30 centimetre deep aquarium to obtain pictures of the same quality. If you wish to carry out underwater photography you need to get a special camera or a camera house. Cheap single-use underwater cameras tend to take comparatively low-quality pictures and can usually not be used more than 5-10 metres below the surface due to their low pressure resistance. They can also be quite expensive in the long run, since you constantly have to purchase new ones. Water quality is naturally also of importance. Taking good pictures in a murky lake will be much more difficult than photographing reef dwellers in the crispy clear waters of the Red Sea. In an aquarium, a large water change is recommended prior to a photo shoot but allow time for the substrate to settle before you start snapping pictures. Floating debris should be vacuumed out and giving the aquarium glass a good scrub can also be a good idea.
