Abstract: The film change bag has an opaque fabric or plastic bag through which a user may put his hands and an opening through which a camera or the like may be inserted. When in use, the bag is maintained in an expanded state by a continuous loop elastic frame inside the bag. The loop is twisted in a way to have a center loop and a pair of end loops essentially touching each other. At the two points where the larger loop crosses itself to form the smaller loops, there are hinge points. The normal state of the frame is with the three loops approximately copolanar for folding the bag. The bag is erected by twisting the elastic loop at the hinge points so that the end loops are roughly normal to the center loop. The elasticity of the loop tends to return it to the folded state. The edges of the end loops remote from the hinge points are therefore connected together by a spring latch for holding the edges a selected distance apart and keeping the frame erect.
