Underwater photography requires specialized equipment that is expensive to purchase and maintain. It also requires skills like scuba diving certification and photographic knowledge that take time and practice to develop. Some of the key equipment needed includes underwater housings for cameras, strobes or flashes, arms to hold the strobes, and lenses suited for different types of underwater photography like macro or wide-angle. With investment of both money and time, underwater photography allows one to capture beautiful images from below the surface.
