Fotokemika's Varycon Variable Contrast Filter Set contains six filters
including grades 0 - 5 in full steps. A cost-effective alternative to
Ilford Multigrade Filters, these filters are the next best thing at a
lower price.
Each
filter is marked in the upper right hand corner with the corresponding
grade number. These filters are optimized for Fotokemika's Varycon
B&W photographic paper but can be used with any brand of paper with
excellent results.
