Paterson Changing Bag

The  Paterson Changing Bag enables you to develop your own film in Cawanol, without any need for a darkroom. Simply put your exposed film in the bag with a can opener, and load it onto a reel, put it in the Paterson Film Processing tank, and close the lid. Take it out of the changing bag, and your are ready to develop! – It helps to practice it first outside the bag, so try this with a cheap or expired film roll first. You could consider the Paterson changing bag your miniature darkroom.

  • Having a changing bag on hand means that a jammed or partly exposed film can be safely removed from the camera and shooting can continue and it will allow a film to be loaded into a developing tank without having to first find a darkroom.
  • It has a fail-safe double skin with a double zip closure and the comfortable inner lining is specially designed to avoid perspiration in prolonged use.
  • The Paterson changing bag is small enough to fit into a camera bag, yet large enough to allow a camera back to be fully opened once inside or a film to be loaded into a tank.
