Tiffen 77OR21 Overview

The 77mm #21 Orange Filter from Tiffen is a filter designed to build contrast in black and white photography and creates separation between the tones.

Tiffen filters are not dyed, but are manufactured by using ColorCore technology. This process laminates the filter material between two pieces of optical glass and grinds down and polishes the glass. The glass is then mounted to the metal ring, which after that can be screwed onto the lens for the desired effect.

Great Filter For Cityscapes

By Kevin McGovern
Rated 5 out of 5

It seems many of the new films react less noticeably to the use of contrast filters than years before, and I am not subtle with their use in my own work. In this area, the atmosphere usually requires a stronger filter for building-sky separation as well, even if an N- exposure and development scheme becomes necessary for adequate rendering of shadows in wet prints. That’s why, I generally use deeper filters for my black and white images, so the #29 Orange is my only orange filter. I can’t say I have done any technical comparisons between the actual bandwidth of filters manufacturers, but have used Tiffen filters for years, with no problems. My only minor gripe is they use aluminum instead of brass rims, which can lead to more frequent jamming, unless extra care is used when installing them. In a perfect world, they would use brass for their rims, and maintain their price point. And my wife would never yell at me, for anything... Users should always keep a filter wrench in their kit when using aluminum-rimmed filters like these. If you get a jam, it’s a must to get even torque around the filter to spare the the threads of both filter and lens. I also treat my filter’s threads with a VERY LIGHT film of synthetic lubricant like SuperLube or Syl-Glide, neither of which reacts with the aluminum or degrades over time. Avoid lithium grease at all costs for all photographic equipment! It’s reactive with most of the alloys used in our precious gear and degrades, turning into a hard cheesy substance, should your equipment be unused for a time. Anyway, Tiffen filters have never disappointed, and are a fine choice, compared to the pricier brands. Of course, Linhof users probably could care less, but still—

Great filter
