Ilford Multigrade Filter Kit 6x6in.
Description / Ilford Multigrade Filter Kit 6x6in.
MULTIGRADE FILTERS are numbered 00–5 in ½ step increments with the lowest filter number corresponding to the softest contrast. They are easy to use with no complicated calculations required when changing from one filter to another - the exposure time for filters 00–3½ is the same which then simply doubles for filters 4–5.
