Formatt Hitech Yellow 8 Filter (5.65 x 5.65")

The Formatt 5.65 x 5.65" Yellow 8 Filter is commonly used for a noticeable increase in contrast with black and white films.

There are occasions when your image needs even more than subtle nudge - something to bring the contrast up even more than a Yellow 6.  The #8  filter is the next step up the contrast ladder and produces more "snap" than either the #3 or #6 filters.
