Choose a layer from the list, then click "Enhance...". The window allowing you to enhance the layer image will appear (Fig. 3.7). The left image is a source image, at the right there is an image with the current settings.

Fig. 3.7. Image enhancement dialog

The dialog contains the following settings for image enhancing:

  • Brightness - make the image brighter/darker;
  • Contrast - increase/decrease color intensity;
  • Saturation - make all colors brighter and richer (setting saturation to zero gives a black-and-white image).

Click "Reset" to restore the default values for all 3 parameters.
