Split-grade printing

On variable-contrast paper you can build a print from two exposures: a soft filter for highlights and a hard filter for shadows. Enter a base time to get a starting split you then refine on the easel.

A starting point, not a formula — expose the soft (grade 00) pass first for highlight density, then the hard (grade 5) pass for black, and fine-tune each with test strips.

About this tool

Split-grade printing builds a black-and-white print from two exposures on variable-contrast paper: a soft grade 00 pass for the highlights and a hard grade 5 pass for the shadows. Enter a base time and target contrast to get starting soft and hard times you refine on the easel.

How to use it

  1. Enter your base exposure time per filter in seconds.
  2. Pick the target contrast for the scene and negative.
  3. Read the suggested soft (grade 00) and hard (grade 5) times.
  4. Expose the soft pass first, then the hard pass, and fine-tune each with test strips.

FAQ

Is this an exact formula?

No. It is a sensible starting split; split-grade is always dialled in on the easel with test strips for the highlights and shadows separately.

Which pass do I expose first?

Usually the soft grade 00 pass for highlight density, then the hard grade 5 pass to set the blacks.
