For printing any of the 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 are supplied in 3 inch and 6 inch square sizes to
fit most enlarger’s filter drawers, and as a set of mounted filters for
below-lens use with a filter holder. The mounted filter set includes a
red safelight filter.
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.
