Kit contains Ilford 9cm x 9cm Grade 2, 3 and 4 filters.

For printing ILFORD MULTIGRADE range of papers on unconverted black-and-white enlargers, ILFORD have produced complete sets of filters for all contrast grades in half grade steps. MULTIGRADE filters do not require any recalculation of exposure times when changing between grades 0 and 3, grades 4 to 5 simply requiring twice the exposure.
