If you work with film this is a must have accessory. If you ever need to safely load or unload film in the field, there is nothing like a good changing bag.

The bag is large enough for working with medium format cameras, handling film and paper in the darkroom. You can load film in developing tanks and paper in the developing drums.

The bag has two layers, each one with its own zipper. It is made of sturdy thin lightproof fabric, so the bag takes surprisingly little space when folded.
