ABSTRACT:
A device for enlargement and development of photographs and particularly adapted to efficiently produce posters in a conventional darkroom and to efficiently develop photographs of different sizes. This device includes a posting pegboard, pegs, and clips to hold photographic sheet material in a single vertical position while producing an enlarged print or poster thereon, developing the print, and rinsing the developed print. A sink is operatively associated to the posting board and includes a trough underlying the latter to collect the drips from the wet prints. The sink includes transverse channels with dividing partitions tightly fitting in these channels and separating the sink into a plurality of basins for development of photographic prints. A lattice rests on a peripheral flange of the sink to form a two-level arrangement with the sink for more versatile handling of prints and use of the device.
