up: Camera scanning

Film holders are an essential part of a high-quality camera scanning setup. Their primary role is to keep the film flat and properly aligned beneath the camera. This is crucial when working at close distances with macro or scanner lenses, especially those with a shallow depth of field and no internal focusing or adjustable aperture. Any curl or unevenness in the film can cause focus inconsistencies, resulting in parts of the image appearing soft or distorted.

Why Film Flatness Matters

Achieving film flatness is one of the most important goals in camera scanning. Because digital scanning is often done at high magnifications, even minor film curvature can push parts of the image out of the lens's focal plane. When the film is flat, the image stays sharp across the entire frame; when it’s not, some areas will be noticeably softer.

Film holders also help prevent light spill by providing a tight mask around the edges of the negative. This keeps unwanted light from bouncing around or causing flare or ghosting, which can degrade image quality—particularly in the shadow areas.

Types of Film Holders

Film holders come in many shapes and formats, but can generally be divided into two main categories:

Sandwich Holders (Pressure-Based)

These holders use two flat surfaces—such as glass, acrylic, or precision-cut masks—to gently press the film flat. This method ensures excellent flatness, especially for curled or older negatives.

Advantages:

Consistent flatness across the frame
Ideal for high-resolution or archival-quality scanning because of the high flatness

Drawbacks:

Slower to operate, since the film must be manually re-sandwiched between scans
Can trap dust, requiring careful cleaning, see Dust Control
Risk of Newton rings if non Anti-Newton glass is used

Examples:

JCC 35mm film strip holder FH-135 Holds up to five 35mm frames in a single glass-free sandwich
Autocarrier: Combines film holder and automated transport system using pressure plates (expensive, 35mm only)

Gate Holders (Non-Pressure-Based)

These film holders provide a thin gate or channel for the film to slide through without direct pressure. The film is held in place but not pressed flat.

Advantages:

Fast and efficient for batch scanning
Simpler handling

Drawbacks:

Less reliable flatness, especially with curled or uneven film
May require external flattening aids for consistent sharpness

These are popular in modular systems like VALOI 360 , Negative Supply, or Essential Film Holder systems, many of which offer interchangeable parts for scanning multiple formats.

Format Compatibility

Some film holders are designed specifically for a single format (e.g., 35mm), while others are part of modular systems that support multiple film types like 120 (medium format) or even large format film. Modular systems offer flexibility but may compromise a bit on rigidity or ease of use compared to dedicated format-specific holders.

Final Thoughts

Finding the perfect film holder is a personal journey—it depends on your workflow, format, budget, and whether you prioritize speed or absolute image quality. From fast gate-style holders to precision sandwich systems, each option comes with trade-offs.

While many commercial holders offer convenience, few deliver perfect flatness out of the box. In most cases, a custom or modified sandwich-style solution will yield the best results, especially when scanning curled negatives or at very high resolutions.

Nikon film holders

Nikon ES-1 (https://www.film4ever.info/gallery#h.2lu5gp7fgo8r ) is one of simpliest ones and can do only slides.
Nikon ES-2 is versatile device good for slides and strips of film . JCC adapter ( https://www.film4ever.info/gallery#h.7xzwe3glpyvo ) is basically the knock-off of Nikon ES-2.
Nikon PB4 and PB6 are very solid and robust devices. If used with Nikon bellows they are rock-solid, if one decides to incorporate them in its own design - certain metal working skills are required. It makes sense to discuss these holders separately as they still unvaluable piece of equipment.
