Most enlarger manufacturers use these filtration values. This table is intended as a guide to making prints on Ilford MG paper when using a Dichroic Head Color Enlarger. You may also use them with other brands of variable contrast paper with good results. Use the Kodak standard for Beseler, Omega, Devere, LPL, Paterson, and Vivitar enlargers. Remember you have a lot of control when using a color head because you can dial in fractions of a contrast grade rather than being limited to 1/2 grade steps. Also these filter factors are just estimates. The age and condition of the filters will affect your results.
