It has been shown by controlled photography of a desert area that for vertical air photography of such terrain the effective photographic light intensity is proportional to the ground illuminance. Exposure tables based on the luminous density law, as used in tables for ground photography, give serious over‐exposure when applied to desert conditions, where the ground approximates to an unbroken plane.
