Colour Enlargers

Calibration figures for single-filter settings on colour enlargers.

These figures can be used as starting points for your own calibration. We actually recommend the use of dual-filtration to keep exposure times reasonably constant across the grades, but the use of single filters will reduce exposure times considerably for medium contrast grades.
