ABSTRACT:
A pliable film holder for large format photographic film includes a relatively pliable, flat film retainer for fixedly yet removably holding a sheet of large format film. The retainer has a window behind which the film is disposed. A relatively pliable, sheet-like slide member completely covers the window when disposed in a first position with respect to the film retainer and uncovers the window to expose the sheet of film to incident light when disposed in a second position. The film retainer and slide member have cooperating guides for guiding the slide member as it is moved with respect to the film retainer. In a second embodiment the pliable film holder includes a relatively pliable, flat film retainer which has a back and a front, the window being in the front. The slide member in this embodiment is a substantially opaque envelope to prevent light coming from the direction of front and back of the envelope to expose the film within when the envelope is in the first position, which is when the opening of the envelope is moved into the double flaps of the film retainer. The film retainer is for use in conjunction with a film adapter.
