Polaroid developed the world's first instant camera systems.
The Polaroid Corporation, bowing to pressure from digital photo systems, stopped selling instant film for its popular SX-70 and 600 lines of cameras. The two systems were similar, but with different film speeds, the 600 films being four times (two f-stops) more sensitive than SX-70 film. Because of this, a system was made to prevent interchange of cartridges between camera lines, a system that is simple to bypass. With one change to the SX-70, it can be used successfully with Polaroid 600 film, which is in more plentiful supply.
Instructions
1. Remove the filter glass from its frame. Carefully use the the needle nose pliers to bend the filter frame in two or three locations. With slight pressure, the glass will pop out.
2. Glue the removed filter glass over the lens in the center of the camera. Use hot glue sparingly on the ring around the outside of the lens and press the glass filter over it, holding the glass in place until the glue sets. This filter cuts the amount of light that will hit the more sensitive 600 film.
3. Open the film door on the camera. Insert the card in the opening, then place the 600 film cartridge on top of the card. Slide the cartridge in about half way, then remove the card, fully insert the cartridge and close the film door. The dark slide will eject and you are ready to take photos.
