Underwater pictures is the most difficult type of photography as it requires many skills other than just simple photography. Those other skills include diving, snorkeling or swimming! In order to take good underwater photos, you must know all of those things, otherwise taking photos safely would be impossible.

Color and contrasts in underwater photos are also big problems especially when you are going deeper or farther away from your subject. The reason for this is that longer wavelengths of sunlight i.e red or orange get absorbed quickly by water, which makes everything underwater looks bluish green in color.
