5. Working with PhotoLine / 5.6 Scanning

### 5.6.7 Brightness/Contrast

By increasing the brightness and the contrast of a scanned image usually increases the quality enormously. In PhotoLine you can finish this task with Contrast/Brightness (View/Toolbars/Contrast/Brightness).

More flexible is Tool/Curves.

The dialog contains two sliders to control the brightness and the contrast.

The curve fields allow you to correct all color channels of the image at once with the first curve field or to correct only a single color channel.
