发明名称 Compact portable darkroom
摘要 A darkroom assembly comprised of a shell consisting of six interconnected rectangular panels formed into a box encloses suitably arranged apparatus and chemicals for making contact and enlarged photographic prints, and further incorporates the features of a pin hole camera. By virtue of the combination of an internally housed safe light and a viewing lens in the upper panel mounted above a red filter window, the operator can observe phenomena within the darkroom. Manipulations within the darkroom are achieved by insertion of the operator's hands through light-tight openings in the opposed side panels of the darkroom. For purposes of storage or shipping, the relative positions of the six panels may be adjusted so as to produce a collapsed structure occupying less space than the erected darkroom.
