ABSTRACT:
A method and apparatus for burning or dodging selected areas of an image formed on photographic paper from a developed negative. A frame is provided with plural spaced light transmissive elements arranged in a grid. To dodge preselected areas of the image formed on photographic paper, one or more cut-outs of light blocking material are placed at selected locations on the grid. To burn preselected areas of the image, a sheet of light blocking material having one or more apertures (shaped as desired) is placed on the grid. In burning and dodging, the frame is held between the developed negative and the photographic paper. Each of the cut-outs may be provided with a tab-like element to facilitate placement of the cut-out on the grid.
