The Formatt 77mm #38 Light Blue Filter is a general contrast filter, primarily for use with black and white film. This light blue filter helps to correct the tendency of reds reproducing too lightly under incandescent lighting. This filter absorbs much of the red tone in the image as well as providing UV attenuation.

There is a 1.5x filter factor with this filter, requiring an increase of 0.6 stop for normal exposure. This filter is constructed from specially formulated CR-39 resin sandwiched between two layers of high-quality Schott glass.
