    Before you start

    Map light and dark into two tones

    • At 100%, Duotone maps image luminance between a fixed dark base and the selected Light tone.
    • Use it for a controlled two-color treatment. Sepia uses a fixed warm transform instead.
    • Only the light tone is editable; the dark base is fixed and output dimensions stay unchanged.
