Quick answer
Loading a 100ft bulk roll of Kentmere Pan 400 into empty 35mm cassettes saves money and lets you choose your exposure count. You'll need a bulk loader, a dark changing bag or darkroom, and empty cassettes.
Why bulk load Kentmere Pan 400?
A single 100ft bulk roll of Kentmere Pan 400 yields roughly 18 rolls of 36 exposures. That's a significant cost saving compared to buying individual rolls. Plus you can decide exactly how many exposures per roll—handy for testing or short projects.
What you'll need
You'll need a bulk film loader (like a Lloyd's or Watson loader), a dark changing bag or completely dark room, empty 35mm cassettes, scissors, and tape. The Kentmere Pan 400 bulk roll comes in a sealed can; open it only in total darkness.
Step-by-step loading process
- Prepare in darkness: In a dark changing bag or darkroom, open the bulk roll can and feed the film end into the bulk loader according to the loader's instructions. Close the loader's light-trap. Check that the film spool turns freely inside the loader; if it binds, you'll get uneven tension.
- Set exposure count: Crank the loader's counter to your desired number of exposures. For 36 exposures, advance the film about 1.6 feet (roughly 50 cm). Many loaders have a built-in counter; if not, mark the film at 1.6 ft intervals. A common mistake is over-advancing the film, which wastes film and reduces the number of rolls you get from the bulk spool.
- Cut and load the cassette: With the film advanced, cut it from the bulk spool using scissors. Attach the film leader to the empty cassette spool with tape, then wind the cassette using the loader's crank or a separate winding tool. Ensure the film lies flat and tight. If the film leader isn't securely taped, the cassette may jam or the film may slip, causing fogged edges.
- Seal and label the cassette: Remove the loaded cassette from the loader, close its light-trap, and label it with film type (Kentmere Pan 400) and exposure count. Store in a cool, dry place until use. Always label immediately; unlabeled cassettes are easy to confuse with other films, leading to wrong development times.
