Dye Concentration controls
• Presets — the controls in this area let you choose a preset effect, save the current settings as a preset,
and delete a preset
• Maximum — controls the amount of dye on the peaks of the texture
If you think of texture as peaks and valleys, the Maximum slider controls the amount of dye on the
peaks, and the Minimum slider controls the amount of dye in the valleys.
• Minimum — controls the depth of the texture. The lower the values, the higher the contrast between
the peaks and valleys. The higher the values, the flatter the image appears.
• Preview — enable this check box to preview the effect in the document window
• Reset — resets the sliders to their default settings
