Adjust exposure
The scanning software automatically selects the optimal exposure settings for the output type applied to the image of a picture. However, if the original picture needs the brightness or contrast adjusted, you can use the Exposure Adjustment tool to increase or decrease:
■highlights (see page 71)
■shadows (see page 72)
■midtones (gamma) (see page 73)
■clipping of white and black pixels (see page 76)
■output levels for white and black pixels (see page 78)
The exposure settings you select will be applied to the final scan.
You can also use the Exposure Adjustment tool to:
■view the distribution of pixels (see page 74)
■read the RGB values of the pixels in the image (see page 74).
The Exposure Adjustment tool is active for the color and grayscale output types.
