Cassette Film • Modular DSLR Scanning System

Control the Negative. Control the Result.

Lab scans are optimized for throughput. This is optimized for consistency.

Precision film holders for 35mm, 120 medium format, and 4×5 sheet film — built for DSLR and mirrorless camera scanning workflows where flatness, alignment, and repeatability are non-negotiable.

1
Hold film flat for sharp, edge-to-edge captures — not “good enough” scans.
2
Lock alignment so your crop and framing don’t drift across rolls.
3
Build a system that scales from 35mm → 120 → 4×5 without rebuilding your setup.

Start with the format you shoot most. Expand later. Keep the workflow.

Flatness
Film curl kills sharpness. Controlled flatness preserves detail across the frame.
Alignment
Stable framing means faster capture, cleaner batches, and less time fixing files.
Repeatability
A workflow you can repeat on demand is what makes “premium” predictable.

A DSLR film scanning system—engineered, not improvised

DIY scanning setups work until they don’t. Small misalignments turn into soft edges, uneven crops, and inconsistent color. Cassette Film is built to remove the variables that make home scanning feel unpredictable.

  • Consistent capture for cleaner Negative Lab Pro inversions
  • Format flexibility without replacing your workflow
  • Faster sessions with less rework per roll
  • Long-term control: scan anytime, re-scan anytime, archive RAWs

Choose your format. Build a system.

The ROI question: “Is home scanning actually worth it?”

If you scan regularly, lab fees compound fast—especially for 120 and 4×5 high-resolution tiers. Use our ROI calculator to compare your real-world lab pricing and estimate your break-even point.

FAQs

How to load film into holders?

Loading negatives into film holders requires a bit of care and attention to ensure that the negatives are properly aligned and free of dust or debris. Here are the general steps to follow:

Clean the film holder: Use a soft, clean cloth or a can of compressed air to remove any dust or debris from the inside of the film holder. This will help prevent scratches or other damage to the negatives.

Prepare the negatives: Optional. Cut the negatives into strips appropriate for your film holder. Make sure that the emulsion side of the negatives (the side with the image) is facing up.

Load the negatives: Slide the first negative into the slot at the side of the film holder. Make sure it is properly aligned so the image is centered and straight. With your free hand, gently pull negatives through the holder.

 Repeat this process for each negative, ensuring they all face the same way and are aligned in the same direction.

What is a film holder?

The Cassette negative film holder is a device used in photography to hold a strip or sheet of photographic film in place during the process of scanning. The film holder consists of two laser-cut cast acrylic sheets with a slot/ opening to allow the film to be inserted.

The negative film holder is designed to keep the film flat and prevent it from curling or warping, which can distort the image and cause problems during the digitizing process. The holders can also be separated to remove dust and particles.

Cassette Film Holders are available in a range of sizes to accommodate different types of film, including 35mm film holder, 120 / Medium Format film holder, 4x5 film holder, and 8x10 film holder.
