Modifying a Polaroid camera for close-up documentation.
Abstract
A standard plus-three-diopter trial lens held in front of the objective lens of an inexpensive Polaroid camera produces close-up photographs of acceptable quality. This simple technique can be used to inexpensively document indications for plastic surgery and provide medicolegal documentation. The 23-millimeter-diameter trial lens provided acceptable resolution, but reduced depth of field; it must be well-centered to avoid vignetting.
