发明名称 Photographic cropping device and method
摘要 A device for producing-cropped photographs is made up of separate pieces adapted to be assembled entirely by feel in a darkroom relative to a conventional enlarger for the making of prints from a photographic image projected by the enlarger. The device includes a base sheet and template sheet or sheets having the same shape and outside dimensions as the base sheet. Both the base sheet and the template sheet or sheets are sufficiently thick and stiff to enable proper alignment thereof entirely by feel in a darkroom of the outer peripheries thereof, relative to a sheet of photographic paper interposed therebetween. Multiple template sheets are preferably provided by packaging the device in kit form. In assembling the device in a darkroom, adjustment of the enlarger is usually carried out relative to the base sheet with the room lighted and prior to placement of the unexposed photographic paper, the base sheet being fastened in place on the enlarger stand as by pressure sensitive tape following adjustment of the enlarger. The invention is also concerned with the method of using the device.
