Exposure Information: Given as f-stop measurements made on a wall grid of 1 ft. by 1 ft. squares, with the light source centered on the grid center, and placed a fixed distance from the wall. The center number is the actual meter reading. The other numbers are the relative change in readings, with meter position, always at grid crossings.
