Overview

The Tiffen 60BR25 is a Red 25 optical filter in Bay 25 bayonet mount, designed primarily for black and white photography. The Red 25 spectral characteristic blocks blue and green light while transmitting red and orange wavelengths — a combination that produces one of the most dramatic sky contrast effects available in-camera. Blue skies darken to near-charcoal tones in B&W conversion, throwing white cumulus clouds into sharp relief without any post-processing. Tiffen manufactures the optical element from high-quality glass using a ColorCore process that dyes the filter material within the glass rather than coating the surface, which contributes to color consistency across the filter's surface and durability over time. The metal mounting ring ensures the bayonet fit remains precise through repeated attachment cycles.

This filter belongs in the kit of any B&W photographer shooting in a Bay 25-compatible system who works outdoors and wants to control tonal relationships at capture rather than in post. It excels in landscape photography — transforming a pale, featureless sky into a dramatic backdrop — and in botanical or garden work, where the filter's ability to darken green foliage creates strong tonal separation from warm-colored flowers. Infrared film shooters use the Red 25 as an entry point to near-infrared effects before committing to dedicated IR filters. The 3–4 stop exposure penalty requires either a tripod or higher ISO, which defines its practical shooting envelope: deliberate, composed work in adequate light.

Pros & Cons

👍 Pros

  • Produces extreme sky-to-cloud separation in B&W — one of the most dramatic tonal contrast effects achievable in-camera without post-processing
  • High-quality optical glass construction preserves image sharpness without introducing chromatic aberration or color fringing
  • Metal mounting ring is more durable than plastic-ring filters and maintains precise bayonet engagement over repeated use
  • Effective with both panchromatic film and digital sensors, making it a versatile tool across shooting formats
  • Creates tonal differentiation between flowers and foliage that is difficult to replicate accurately in post-processing

👎 Cons

  • Bay 25 bayonet mount is a specialty fitting — incompatible with standard screw-thread lenses without a specific adapter
  • Requires 3–4 stops of exposure compensation in daylight, making handheld shooting in low light impractical
  • Effect is so heavy that it produces unnatural results for anything other than intentional high-contrast B&W work — not a subtle, versatile filter
  • Renders skin tones very light in B&W portraits, which may be unflattering depending on the photographer's intent

Frequently Asked Questions

Red 25 is a deep red filter that blocks most blue and green wavelengths while passing red and orange light. In practical terms, it darkens blue skies to near-black in B&W photography, makes white clouds pop with extreme contrast, and lightens red and orange subjects. Expect to add 3–4 stops of exposure compensation when shooting in daylight, as the filter significantly reduces the light reaching the sensor or film.
Bay 25 is a bayonet mount size specific to certain older medium format and view camera systems, not a standard screw-thread size. Before purchasing, confirm your lens or filter holder uses a Bay 25 bayonet fitting. This is not compatible with standard screw-mount (mm diameter) filter threads without an adapter.
It works with both. On digital cameras, the red channel dominance will be visible in RAW files and can be converted to high-contrast B&W in post. For in-camera B&W JPEG shooters, the effect is rendered at capture. The filter is particularly effective with panchromatic B&W film, but the optical effect is the same across any medium that records visible light.
Yes. Green foliage absorbs the red wavelengths this filter passes, causing leaves and grass to render darker in B&W — the opposite of the sky effect. This creates a dramatic separation between flowers or warm-toned subjects and their green backgrounds.
Technically yes, but the heavy red cast it imparts makes color images unusable for most purposes. It is designed and optimized as a B&W contrast control filter. Color shooters looking for sky enhancement should use a polarizer instead.
