A darkroom bag is a light-proof bag used in photography to load and unload film into developing tanks in complete darkness. It is essential for photographers who develop their own film, as it prevents light from fogging the film and ruining the images.
The best darkroom bags for 2 tank reels are typically made of a thick, opaque material, such as canvas or nylon. They have a large opening that allows easy access to the tanks, and they are usually equipped with a drawstring or zipper to close the bag securely. Some darkroom bags also have a built-in changing bag, which allows photographers to load and unload film without having to remove the tanks from the bag.
