This L-shaped scale is similar to the ABFO No. 2 Scale; however, it is printed in inches rather than the metric system. It is made of the same heavy, laminated plastic with a nonglare finish and has 3 crosshair circles to assist in correcting parallax. There are alternating black and white bars to allow for measurements of grossly over or underexposed photographs and bars of approximate 18% gray scale for color corrections.
