GUIDANCE TO UFO PHOTOGRAPHERS

This document, titled 'GUIDANCE TO UFO PHOTOGRAPHERS' and marked with the reference number T-18, provides a set of ten technical recommendations for individuals attempting to photograph Unidentified Aerial Phenomena. The instructions emphasize the importance of camera settings, suggesting that the camera be set to infinity and that fast film, such as Tri-X, be utilized. For moving objects, the guidance advises using shutter speeds no slower than one-hundredth of a second, with adjustments based on lighting conditions such as dusk, cloudy days, or bright sunlight. Photographers are cautioned against moving the camera during exposure and are encouraged to take multiple pictures, including ground references. The document provides specific advice for objects appearing close by, recommending that the photographer change their location by 40 to 60 feet to establish a base line for technical analysis. For distant objects, it suggests moving a half-mile or more to take another series of pictures. Furthermore, the guidance instructs photographers to remain in place after taking initial pictures and to slowly turn 360 degrees to capture overlapping, eye-level photographs of the surrounding countryside. Finally, the document stresses the value of the original negative, advising that it be processed with care and that any reproductions for technical study be made from the original, ensuring the entire frame, including borders and sprocket holes, is visible.
