The Tiffen 86mm Coarse Thread #9 Yellow Filteris a basic contrast filter, primarily for use with black and white film. This medium yellow filter slightly darkens skies, helps to cut through haze, and improves overall contrast. It is a common contrast filter for black and white photography, producing an accurate tonal range and compensating for the blue sensitivity of panchromatic film.

There is a 2x filter factor with this filter, requiring an increase of 1 stop for normal exposure. 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.

A: First you have to open the plate up fully by turning the quickset level fully open, then you tilt your plate and slide it into one of the long side of the plate, because the plate is open, then you can push the other side of the plate into place (it will not work unless the plate is fully open). Next you close the quickset lever one notch which allows you to adjust the position, then another notch to fully lock it.
