For this tip you will need a black electrical tape, scissors for cutting the tape and your favorite 35mm frame format mask for your Diana F+
Start by attaching your 35mm back to your Diana F+, make sure that you do NOT have a frame format mask in place. Now place a strip of the tape across the middle of the opening spanning from left to right. Be sure to leave space at the top and bottom of the frame. Next add your favorite 35mm film and fire away. Keep in mind that only the top and bottom of the film will be exposed during your first round of shooting. Once the roll is finished rewind it and remove the black tape from the inside of the camera. Now find your favorite frame format mask and add it to your 35mm back. Time to load the film and shoot again!
