Obtaining a photograph that provides genuine information entails strict uniformity and standardization. As noted throughout this discussion, this is best accomplished through use of a simple and consistent scheme for photography. To identify the aspects of the scheme that give optimal results it is wise to run several test rolls of film at various camera settings and to mark the camera accordingly. In this manner the same procedure is always followed. If all the foregoing criteria are met, the medical photograph will serve as an ideal clinical record, medicolegal record, teaching tool, and instrument for critical analysis of results. The different steps are recommended to ensure uniform medical photography: one should use a 35 mm, single lens reflex camera body with a 'grid' type of viewing screen; a 90 to 105 mm. lens is used to avoid distortion and provide a comfortable patient to camera working distance; an electronic spot flash (avoiding a ring flash except for deep cavity photographs) can be supplemented with an overhead 'kicker' light; a sky blue, nonglare background is ideal; kodachrome 25 film is recommended for most situations; careful positioning of the patient is critical. Observe the Frankfort plane horizontal; one should avoid the pitfalls of photographic misrepresentation; the key to successful uniform medical photography is consistency of equipment and positioning.
