Film Developing Tanks

People use developing tanks with special film reels to develop film rolls or sheets. After loading your film on the reel, you place it in a film developing tank with the chemistry mixture to develop. Most tanks have instructions for the proper amount of developing chemicals for specific film formats. The reel locks onto a center post, and chemicals mix consistently during the process to ensure the film gets a thorough coat. Using film developing tanks with darkroom print washers and dryers helps you develop your film from start to finish.
