Founded in 1879, Ilford Photo is known worldwide as on of the most popular manufacturers of black-and-white film, paper, and chemicals.
ILFORD MULTIGRADE Filter Sheets are for printing on Multigrade (and Variable Contrast) papers. Multigrade papers make it possible to produce a wide range of contrast grades from a single type of paper simply by changing the color of the exposing light. Therefore rather than having to maintain a stock of the various contrast grades, the printer only has to keep a single type of paper and a number of filters.
ILFORD have produced a complete set of twelve (12) numbered filters for all contrast grades in half grade steps. These filters do not require any recalculation of exposure times when changing between grades 0 and 3.5, grades 4 to 5 simply requiring twice the exposure.
Also available in kits: 3x3, 3.5x3.5, 6x6 sizes, and "Under the Lens"
