Multigrade

Variable contrast bromide paper.

  • Multigrade Filters. Set of 5 filters (1 - 5) in red/yellow box. These date to the late 1950s.
  • Ilfospeed Multigrade. Packet of 25, 8" x 10" papers. MG44M Pearl, Medium-weight. White packet.
  • Ilfospeed Calculator showing exposure increase when using Multigrade filters.

Multigrade is a variable contrast paper. The original version of the paper was coated with two emulsions one is sensitised into the blue/green part of the spectrum and is 'contrasty', the other is an ordinary 'soft' emulsion and not colour sensitised and therefore largely responsive to blue light only. Filters are used to adjust the proportion of blue to green light reaching the paper thereby altering the contrast; yellow filters will reduce the proportion of blue light giving higher contrast characteristics, magenta filters (used in the 1954 version) would reduce the proportion of green light giving softer characteristics.

Multigrade was first introduced in 1940, this original version was improved during the early part of the war but was then withdrawn. At first four filters were used, blue (M.G.20B) and three yellow (M.G.3, M.G.7, M.G.20). These gave the contrast grades of: very soft, M.G.20B; soft, no filter; normal, M.G.3; contrasty, M.G.7; ultra contrasty, M.G.20. The later filter set comprised five filters, ranging from pale yellow to deep yellow (labelled 4, 6, 8, 10 and 12).

Multigrade was withdrawn during the latter part of the war and re-introduced in 1954. Only three yellow filters were used at this time labelled Low (pale yellow), Medium and High (deep yellow). In the late 1950s the filter set was increased to five with the addition of two magenta filters, (these were labelled 1, 2 for magenta and 3, 4 and 5 for yellow). Presumably the emulsion was changed at this time.

The paper was again withdraw and re-launched as Ilfospeed Multigrade around 1978. Newer versions of Multigrade use three emulsions rather than the two of the original version.

Multigrade was developed by F. F. Renwick, a director at Ilford, it was made public at the Royal Photographic Society meeting held on the 21st May 1940, the paper was published in the August issue of the Photographic Journal. At the time Ilford must have had very high hopes of Multigrade, these were not fully realised in the following years leading to the paper being withdrawn.
