Abstract: A light level meter composed of a fiber optic cable having a light receptor end coupled to a conventional light meter is used for measuring illumination levels in spatially limited locations. By the method of the invention, a reference camera is calibrated for proper exposure settings using a series of test exposures. A light level reading is then taken using the fiber optic cable coupled light level at a location preferably near the camera lens. Identical secondary cameras are adjusted to have the same exposure settings as the reference camera, and the illumination for the secondary cameras is adjusted to match that of the reference camera by matching the secondary light level with the reference light level using the fiber optic cable coupled light level meter positioned at the same relative location at the secondary cameras as used for the reference camera.
