An inexpensive time and instantaneous shutter suitable for a magazine hand camera may be made of cardboard as follows. Cut a piece of stout pliable card - a good photographic mount answers well - to the pattern shown in Fig. 1. Next cut a piece like Fig. 2, and attach at A to the first piece on the underside with a stud or rivet U. Bend under, flat, the two pieces B and C (Fig. l),and attach to the inner board, thus forming a support, and leaving a space for the shutter to work in. Now cut in thin metal a piece like Fig. 3, and bend on the dotted lines. Force the points D and E through the card at 1' and G (Fig. 2), and turn these and the flaps Hand I down flat, thus holding it firm. Fasten a piece of fine black cord to H and I, and bring through the two opposite sides of framework, and fasten outside a button or bead. By this means the shutter may be pulled from side to side. Now fasten a rubber band by a slip-knot through K (Fig. 1), and put the other end of the loop over L. If the shutter is now pulled over by the right-hand button it will need only a slight pull of the left to cause it to spring across and give an instantaneous exposure. Time exposures may also be given.
