Understanding gradient map effect

Gradient mapping assigns colors to positions along the source image's tonal range.

Set dark and light endpoint colors first, then check neutral midtones.

A practical workflow

  1. Choose the required source files, if any. Files are handled as stated in the workspace privacy label.
  2. Set the available controls and apply the operation.
  3. Compare the actual output, check its dimensions and download the generated file.

Decisions and limitations

  • Strength (%)
  • Radius or pattern size (pixels)
  • Primary color
  • Secondary color

16 megapixels maximum. Artistic treatments are algorithmic approximations with adjustable settings. Exported PNGs are flattened. For two-image operations, the second image must match the first image dimensions.
