Procedures for Wide Angle Underwater Photography. Photo Entrance Procedures for Wide Angle Underwater Photography. Wide angle shots create a dramatic effect of the surroundings which include subject matter, background, other actions and a contrast of color of water to the surface or sunlight. Wide angle lenses offer three key advantages in underwater photography. A larger image of view, a higher depth of field that will be in focus and the focal point can be less than a foot from the lens.
Most camera lenses are like a four by six picture frame.
Holding the frame six inches away from the face will result in what a thirty-five millimeter lens will view. Move the frame to one inch is what a fifteen millimeter lens will project. This wider field of vision allows a larger contrast in background reef and divers interaction with the subject. Another benefit is the contrast in water colors. Wide angle lenses can create problems when a divers hand reaches out to attract a fish.
