Scanning Black-and-White Film

Black-and-white negative film renders images with inverted brightness values: dark shadows appear light, while bright areas such as clouds appear dark. When printing, these tonal values are reversed again.

Black-and-white film is typically processed as negatives, although black-and-white slides also exist. In general, the following explanations apply to both types, even though most remarks—especially those concerning tonal inversion—refer to the more common negatives.

When scanning black-and-white film, color is not a concern, as the image consists solely of shades of gray between black and white. A scanner’s ability to accurately capture the full tonal range depends on both its technical capabilities and the correct software settings.

VueScan is particularly well suited for scanning black-and-white film, as it provides extensive controls that allow precise adjustment of the scanning process.

No automatic dust and scratch removal!

Infrared-based dust and scratch detection does not work with conventional black-and-white film. The metallic silver that forms the image is interpreted as dust in the infrared channel.

There are exceptions, such as Kodak BW400CN and Ilford XP2, which are processed using the C41 color negative process. These so-called chromogenic black-and-white films support effective automatic dust and scratch removal. Unfortunately, Kodak BW400CN is no longer available. That is regrettable, as both ISO 400 films are sharp and very fine-grained.

For all other black-and-white films, ICE (infrared cleaning) must be disabled to avoid image artifacts. The competing software SilverFast includes a feature that claims to remove scratches from conventional black-and-white film, but in practice it is not effective.

Choosing the right scanner

Many scanners are designed to handle very dense (dark) areas of film. Early film scanners often failed to resolve these regions into distinct tonal values. As a result, shadow areas appeared as solid black (or white after inversion), with no detail. This limitation is described by the Dmax value. Manufacturer specifications, however, are often unreliable and frequently exaggerated, especially for devices released after around 2000.

Flatbed scanners

The very old Agfa Snapscan 1236s flatbed scanner with a transparency unit was rated at a Dmax of 2.4. Dedicated film scanners are often specified with Dmax values between 3.2 and 4, although the practical difference is often negligible.

Data from the 1982 "Labor-Technik” (German Publication) reference shows that commercially available film rarely exceeds a density of 3.8, while color negative film is usually below 3. This means that, in theory, most modern scanners should be capable of capturing even the densest areas. In practice, however, Dmax specifications tend to be overstated.

Despite its age, the Agfa Snapscan 1236s is still capable of digitizing glass plates and large black-and-white negatives with pleasing tonal gradation.

That said, using such outdated hardware is no longer recommended. Flatbed scanners from Epson’s Perfection Photo series are a much better choice.

The Epson Perfection 3200 Photo is an excellent model and widely available on the used market at low cost. Newer models offer little improvement for black-and-white film, as the added infrared cleaning feature is ineffective in this context.

The Epson Perfection 4990 Photo or Epson Perfection V750 Pro / V850 Pro are even better options, especially if you also plan to scan color film.

Highlights are the real challenge

The main difficulty in scanning black-and-white film lies not in the dense areas, but in the brightest parts. No film is completely transparent, and even black-and-white film may show slight color casts in its clearest regions.

Very bright, nearly transparent areas are difficult to capture. After tonal inversion, these correspond to dark regions in the final image. Many scanners struggle to differentiate subtle tonal variations here, leading to abrupt tonal transitions or loss of detail.

Film scanners and black-and-white

This issue is generally less pronounced with flatbed scanners than with high-resolution film scanners such as the Nikon Coolscan 5000. While excellent for color film, it is less suitable for black-and-white work: ICE does not function, and its directional light source tends to emphasize scratches rather than conceal them.

Among enthusiasts, the Polaroid Sprintscan 35 Plus is still regarded as a capable specialist for black-and-white negatives. Alternatively, Plustek OpticFilm scanners from the 7000 and 8000 series are solid choices.

Recommended settings for black-and-white negatives

The following adjustments provide a good starting point:

Tab: Filter

Disable all options.

Color

Black point: 0.001 (or 0.002)
White point: 0.01
Manufacturer B/W: KODAK
Brand B/W: Internegative
Type B/W: any setting

The white point must never remain at the default value of "1”. Only the "Internegative” setting allows full use of the available tonal range.



Output

Enable TIFF output
File type: 16-bit grayscale
Disable JPEG

Saving as a 16-bit TIFF is essential to preserve maximum flexibility for later adjustments.

Film selection

It is not advisable to select the actual film type. The "KODAK Internegative” profile consistently provides the best control over the full tonal range.

White and black point

Scratches are often brighter than the actual image content and can distort measurements. The white point should therefore be set so that scratches are not given undue weight.

16-bit grayscale (TIFF format)

Because optimal settings are difficult to determine, it is best to preserve the entire tonal range during scanning. As a result, images may initially appear flat and require post-processing.

Final adjustments—such as contrast and tonal correction—should be performed later in image editing software like Photoshop.

For large collections, using automated actions can significantly speed up the workflow.
