FOMA VARIANT correction filters are designed to control contrast in the exposure of multigraded black and white papers, e.g. FOMASPEED VARIANT, FOMABROM VARIANT, FOMATONE MG etc. FOMA VARIANT filters are manufactured in a complete set of 6 pieces; the set consists of 3 types of filters, two pieces of each: yellow (Y), light magenta (M1) and deep magenta (M2). The set allows control of final grading in 7 grades (including exposure without filtration) from extra light to ultra hard (see “types” table).
