Printed on applied label on verso, RC: Infrared photography which uses film sensitive only to infrared \ rays has made large strides in the aerial photographic field. Until \ recently very slow exposures were necessary. Now good infrared photo- \ graphs which penetrate haze can be made at 1/50 of a second. Note \ the clarity of this long-range oblique photograph made from 20,000 ft. \ and embracing an area of many hundred square miles. Lake St. Marys \ lies like an ink blot in the center.
