PROCEDURES 



We placed the 4/8 test pattern, which was mounted on a steel frame, in an up- 

 right position. It was then possible to mount the cameras to be tested equi- 

 distant from the center of the test pattern. 



We decided on a distance of 2 feet from the center of the test pattern for the 

 lens and corrective port tests so that we would fill the frame with the test 

 pattern to the corners of the photograph. 



Since the test was done in black and white, it was found that artificial light 

 was of no use; therefore exposures for 35mm cameras were made with an UW light 

 meter (Seconic) , The Panatomic film was rated at ASA 32. 



Number tags on the test pattern were used to identify camera housings and lenses.
