Abstract
A portable, collapsible darkroom is provided which permits the operator to develop photographic film at virtually any location. Left and right side panels, a back panel, top panel and front door are removably secured to one another to define a light tight enclosure. Sleeved arm ports and a view port are provided on the front door to provide the operator with physical and visual access to the darkroom. A photographic enlarger may be placed within the enclosure and any desirable configuration of the enlarger, film and photosensitive paper may be achieved. The present invention further provides for the separation of film, photosensitive material and other photographic equipment from chemical processing solutions used to complete the processing of a photographic print.
