Polaroid type 57 sheet film (ASA 3000) has been evaluated as a means for recording x‐ray Laue and pinhole diffraction photographs; both transmission and back reflection geometries have been employed. Consideration has been given to the effect of x‐ray tube target material, tube voltage and current, exposure and processing times, collimator size, and specimen‐to‐film distance on resultant pattern quality. Examples are given which illustrate the the ability to obtain high quality Polaroid film patterns in considerably less (5 to 20%) time than is required for comparable wet process films.

Although the Ilford film is considerably faster than the Ansco, the elapsed times per pattern are comparable, for it was necessary to expose the Ilford film at lower voltage to maintain high pattern quality.
