Removing selected color ranges from an image can be used to create a variety of moods and artistic effects. Here's how to use Achroma to do this with your images.

Select an image and adjust the settings to control the color ranges removed from the image. As adjustments are made, the Preview display will update to reflect the changes.
Settings may be copied from one image to another using the Lift and Stamp buttons on the toolbar.
