GUIDANCE TO UFO PHOTOGRAPHERS

This document, titled 'GUIDANCE TO UFO PHOTOGRAPHERS,' serves as a technical instructional guide for individuals who may encounter and attempt to photograph unidentified aerial phenomena. The text outlines ten specific recommendations to ensure that any resulting imagery is of sufficient quality for subsequent technical analysis. The instructions cover fundamental photographic practices, such as setting the camera to infinity and utilizing fast film, specifically citing Tri-X as an example. Regarding the mechanics of capturing moving objects, the guide advises using shutter speeds no slower than one-hundredth of a second, noting that the specific shutter and f-stop combination should be adjusted based on prevailing lighting conditions, such as dusk, cloudy days, or bright sunlight. The document emphasizes the importance of stability, explicitly warning against moving the camera during exposure. It encourages the capture of multiple images and suggests including ground references to assist in later analysis. For objects appearing close, the guide recommends changing the photographer's location by 40 to 60 feet between shots to establish a baseline. If the object is distant, the photographer is advised to remain stationary or, if possible, to drive a half-mile or more to capture a new series of images from a different perspective. Furthermore, the document instructs the photographer to perform a 360-degree rotation after the initial event to capture the surrounding landscape, which is deemed valuable for contextual analysis. Finally, the guide stresses the preservation of original negatives, recommending they be processed with care and that reproductions for technical study be printed to include the entire frame, including borders and sprocket holes.
