Checking for clipping of pixels

The Exposure Alert buttons in the Exposure Adjustment tool warn you of areas of a color or grayscale image that contain no detail in the lightest and darkest areas of the image. The lightest area will print as the color of the paper, with no ink or toner, and therefore no detail. The darkest areas will print with the blackest color of ink or toner, saturating the area with the same color of black with no visible detail.

The Exposure Alert buttons in the Exposure Adjustment tool are:

■ – for viewing white pixels that will be clipped in the final scan

■ – for viewing black pixels that will be clipped in the final scan
