Photographing crustaceans underwater

Digital imaging has revolutionized underwater photography, greatly simplifying (and making affordable) what was once a very challenging and expensive undertaking. A wide variety of cameras and housings are now available that offer unprecedented versatility for recording photographs and even video. Even with all of these technological advances, the basic techniques of strobe placement, aperture setting, shutter speed, and other variables remain largely unchanged from those used to shoot film, the greatest advantages being the ability to immediately view the results and the much larger number of images that can be taken during a dive.
