Technote: a simple technique for comparative wound imaging.
Photographs of wounds often appear to decrease or increase in size due to the distance of the film plane from the wound. These variations in size tend to confuse and confound the observer. To accurately depict the healing progress of a wound, comparative imaging must be utilized; that is, the "image" of the wound must be the same size on the film plane for each exposure. This can only be accomplished if the plane of focus and the distance from the wound are constant for each exposure.
