A practical step-by-step guide to bulk loading Kentmere Pan 200 from a 100ft roll into reusable 35mm cassettes, with beginner checkpoints and common mistakes to avoid.
Quick answer
To roll your own 35mm film from a Kentmere Pan 200 bulk roll, work in complete darkness with a bulk loader and reusable cassettes. Load the 100ft roll into the loader, set the exposure count, attach a cassette, and wind the desired number of frames—then repeat for each cassette.
Why Kentmere Pan 200 suits first-time bulk loaders
Kentmere Pan 200 is a forgiving black-and-white film with enough speed for daylight and bright interiors, so minor exposure variations won't ruin a whole batch. That makes it a sensible choice for practicing your loading technique without the pressure of a premium stock. The 100ft roll yields roughly 18 cassettes at 36 exposures, giving you plenty of chances to refine your process.
One trade-off: bulk loading requires an initial investment in a loader and cassettes. If you only shoot a roll or two per month, the savings may take longer to materialize. But if you shoot regularly, the per-roll cost drops noticeably.
Choosing cassettes and a loader
You'll need a bulk loader and reusable 35mm cassettes. Plastic cassettes with snap-on caps are easier to open and reuse, but metal cassettes with screw caps tend to last longer. Whichever you choose, make sure the light trap is intact and the caps fit snugly—light leaks will fog your film.
WALKENS House of Film can supply empty 35mm cannisters with your order if you ask. That saves you from hunting down used cassettes, which may have worn light traps.
Working in complete darkness
Every step that exposes film—opening the bulk roll package, loading the loader, and attaching film to the cassette spool—must happen in total darkness. A changing bag works if you don't have a darkroom, but make sure it's large enough to move your hands freely.
A common mistake is assuming a dim room is dark enough. Even a small LED indicator can fog film. Turn off all lights and wait a minute for your eyes to adjust before opening anything.
Step-by-step: loading Kentmere Pan 200 into cassettes
- Set up your workspace: In a darkroom or changing bag, lay out the bulk loader, the 100ft roll, your cassettes, scissors, and tape. Keep everything within reach so you don't have to fumble in the dark. Check that your scissors and tape are positioned before you turn off the lights.
- Open the bulk roll in darkness: Remove the Kentmere Pan 200 roll from its packaging and load it into the bulk loader according to the loader's instructions. Most loaders have a spindle or chamber that holds the roll securely. Make sure the film feeds smoothly and doesn't bind—if it does, reseat the roll before closing the loader.
- Attach film to the cassette spool: Open a cassette, locate the spool, and use tape to secure the film leader to the spool. Trim the film end straight if needed. Then insert the spool into the cassette body and close it. Test that the spool turns freely and the film is securely attached before closing the cassette.
- Set the exposure count and wind: Set the loader's counter to your desired number of exposures (e.g., 36). Crank the handle until the counter reaches zero, then stop. Cut the film, leaving a short leader. Double-check the counter before winding—over-winding wastes film and can jam the loader.
- Finish the cassette and repeat: Attach the film leader to the cassette's take-up spool if needed, close the cassette, and label it with the film type and exposure count. Repeat for each cassette. Label cassettes immediately so you don't mix up different films later.
