Tiffen 49mm Black & White Three Filter Kit

The Tiffen 49mm Black & White Three Filter Kit combines the essential yellow #6, green #13, and red #25 contrast filters together, along with a four-pocket filter pouch, to provide a convenient solution for producing varying degrees of contrast when working with black and white film.

Tiffen filters are made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 10,000th of an inch, and then mounting to precision metal rings.
