Filter Settings for Colour Heads.
The settings in the table below will mimic the characteristics of Ilford Multigrade under-lens filters fairly well and allow you to use the filters built into your colour enlarger. Some enlarger models may require an additional exposure compensation as filter factors vary.
Enlargers using Kodak filtration units: Advena, Beseler, Chromega, DeVere, Fujimoto, IFF, Jobo, LPL, Omega, Paterson, Simmard, Vivitar
Enlargers using Durst filtration units: Dunco, Durst, Kaiser, Kienzle, Leitz, Lupo
If anyone has half-grade figures for Meopta we’d love to hear from you 🙂
If you use fixed grade as well as variable contrast papers, you can enter calibration data for them in just the same way and the meter will tell you which grade to use as usual. Some papers, such as Kentmere Kentona and Art Classic, are only available in one grade – if you use more than one type of single-grade paper you can use one PAP channel for all of them, selecting paper type by “grade”. For example, PAP8 Grade 1 = Art Classic, PAP8 Grade 2 = Kentona, and so on. (Do note however that if you subsequently change the position of a fixed-grade paper, you may have to alter the exposure offset. For example, if you move Art Classic from PAP8 Grade 1 to PAP8 Grade 2, you will need to recalibrate owing to the offsets incorporated in the Analyser’s software.)
