Tongs may seem like such an inconsequential piece of equipment, but they have sparked some debate over the years. Many experts say you should use them and many say you shouldn't. They are used to handle the photographs as you are developing them and moving them from tray to tray. You should never really put your hands into developer or touch the film or paper unless you're wearing gloves. The first time you should touch your prints without gloves is when you are taking them from the wash. Many of the chemicals used in a darkroom can be dangerous to your skin. Also, if your hands have been in the developer they can contaminate the photo paper. Wet hands can also lead to an electric shock in the darkroom. You should look for tongs that grip the paper well without damaging it. You may need tongs for the developer, stop bath and fixer. Try to keep each pair of tongs in its own tray to avoid contaminating the other trays. Tongs come in various shapes, sizes and styles and can usually be found for less than $10.
