Overview

The Tiffen 6785B 67mm 85B Warming Filter is a color conversion filter designed for a specific and important task: correcting the color temperature mismatch when tungsten-balanced film is used in daylight conditions. Without this filter, tungsten film shot outdoors produces a strong blue cast because the film is calibrated for the warmer 3200K light of tungsten bulbs, not the cooler 5500K light of the sun. The 85B filter places an amber-toned optical element in the light path that shifts incoming daylight down to the 3200K range, allowing tungsten film to render colors accurately without any post-processing correction.

Built to Tiffen's standard manufacturing quality in the United States, the filter threads onto any lens with a 67mm filter diameter. At 0.18 pounds, it adds negligible weight and bulk to your setup. While the advent of digital white balance has reduced the necessity of color conversion filters for many photographers, the 85B retains its value for film photographers, as well as for digital shooters who prefer to establish a warm tone optically rather than relying on software adjustments. The filter can also be stacked with other 67mm threaded filters, though care should be taken with wide-angle lenses to avoid vignetting from the combined filter thickness.

👎 Cons

  • Primarily designed for tungsten film, offering limited practical benefit for most digital photographers
  • Primarily designed for tungsten film use, which limits its relevance for most digital photographers
  • Very niche use case — digital cameras can replicate the effect through white balance adjustment
  • Largely unnecessary for digital cameras that can adjust white balance in-camera or in post
  • Only corrects for a single specific color temperature shift, offering no adjustability
  • Only available in 67mm size, requiring step-up or step-down rings for other lens diameters
  • Modest light loss of roughly 2/3 stop requires exposure compensation
  • Only available in 67mm, requiring step-up or step-down rings for other lens sizes
  • No multi-coating mentioned, which may affect flare resistance compared to coated alternatives
  • Single fixed conversion factor — cannot fine-tune the degree of warming effect
  • The strong warming effect is fixed and cannot be dialed back without removing the filter
  • Does not include a filter pouch or protective case for storage
  • Minimal light loss still requires exposure compensation of approximately 2/3 stop
  • Minimal light loss still requires exposure compensation in manual shooting
  • No multi-coating specified, which may contribute to additional lens flare in backlit conditions
  • Minimal feature information provided, with no details on anti-reflective or protective coatings

Frequently Asked Questions

It shifts the color temperature of incoming light from approximately 5500K (daylight) down to 3200K (tungsten), allowing tungsten-balanced film to produce accurate colors when shooting in daylight conditions.
The 85B is a color conversion filter that shifts the color temperature from 5500K (daylight) down to 3200K (tungsten), allowing tungsten-balanced film to produce accurate colors when shooting outdoors.
The 85B is a color conversion filter that shifts the color temperature from approximately 5500K (daylight) down to 3200K (tungsten), adding a strong warming effect to your photos.
The 85B filter shifts the color temperature from approximately 5500K (daylight) down to 3200K (tungsten), adding a warm amber tone. This corrects the blue color cast that occurs when shooting tungsten-balanced film in outdoor daylight conditions.
While the 85B was originally designed for tungsten film shooters, digital photographers sometimes use it to add a consistent warm tone in-camera without relying on white balance adjustments or post-processing. However, since digital cameras can adjust white balance electronically, the filter is most essential for film users.
While the 85B was originally designed for shooting tungsten-balanced film in daylight, it can also be used with digital cameras as a creative warming filter. However, most digital shooters achieve similar results with white balance settings.
While digital cameras can adjust white balance electronically, some photographers use the 85B to achieve a warm color cast in-camera without post-processing, or as a creative warming effect for video work where a consistent look is desired across takes.
While digital cameras can adjust white balance electronically, some photographers use the 85B for in-camera warming effects or to reduce post-processing work when a consistent warm tone is desired across a shoot.
An 85B filter typically reduces exposure by approximately two-thirds of a stop, so you will need to compensate slightly when metering.
The 85B typically requires an exposure compensation of about 2/3 of a stop, which is a modest amount that most cameras can handle without difficulty.
This filter fits lenses with a 67mm front filter thread. Check the front of your lens or lens cap for the thread size marking.
Yes. The filter has a 67mm thread and screws directly onto any lens with a matching 67mm filter thread.
The 85B filter typically reduces light transmission by approximately 2/3 of a stop, so you will need to compensate your exposure slightly when using it.
Tiffen filters are made with ColorCore glass technology, using dyed optical glass that resists fading and maintains consistent color accuracy over time.
No. This is a 67mm threaded filter. For lenses with a different thread size, you would need either a 67mm version of the lens or a step-up/step-down adapter ring.
This filter fits lenses with a 67mm front filter thread. Verify your lens thread size on the lens cap or barrel markings before purchasing.
The Tiffen 6785B is manufactured in the United States.
Yes. This Tiffen filter is manufactured in the United States.
Yes, the 85B filter has a filter factor that reduces light transmission by approximately 2/3 of a stop, which you'll need to compensate for in your exposure settings.
Yes, you can thread additional 67mm filters onto the front of the 85B, though stacking multiple filters increases the risk of vignetting, particularly on wide-angle lenses.
