Foma: Multi contrast filter set 9x9 cm
Gradation levels 0-5
Vario contrast filter
To control the contrast of b/w multi-grade papers.

Foma Variant correction filters are needed to control the contrast of black and white variable gradation enlarging papers during positive exposure. The Vario Contrast filter set can be used for all black and white papers with variable gradation and consists of two filters of the levels (Y) yellow, (M1) light magenta and (M2) dark magenta. The set allows to control the final gradation over 7 levels from extra soft to ultra hard.
These foil filters are needed to control the gradation of Vario papers.
The Foma filter set consists of 2 filters each in the following gradations: - 0 Extra- Soft - 2 Special - 4 Hard

If you put the filters on top of each other, you get the steps: - 1 Soft - 3 Normal - 5 Extra hard
The filters are either placed in the filter drawer of the enlarger or held under the lens. They should be either above the condenser or directly under the lens in order not to reach the focal plane of the image (e.g. do not place them under the condenser!). The filters can easily be cut to the right size with scissors or a cutting machine.

Attention: The coating of the filters is sensitive to moisture! Do not touch with wet hands!
Unfortunately, we cannot accept a complaint if the paint layer has come off due to improper handling.
