The Brightness/Contrast command allows you to brighten, darken or adjust the luminance (contrast) of the active picture or selected area.


Two slider controls are provided to perform these adjustments - one for Brightness and one for Contrast. Drag the Brightness slider to the left to darken the picture or drag it to the right to lighten the picture. Similarly, you can drag the Contrast slider to the left to decrease the contrast or to the right to increase the contrast.


The Reset buttons can be used to clear any adjustments made to one of the sliders. You also can enter a value with the keyboard by clicking on the edit control to the right of each slider.


The original picture and the effects of your changes are shown in the Before and After preview windows. Drag the vertical slider to adjust the magnification level of the preview images. Click the button to shrink the preview images so that they fit completely within the preview window, or click the button to display the preview image actual size (1:1). If needed, you may move the preview to display a different portion of the picture using the scroll bars or by dragging its center with the mouse. The button can be used to quickly zero in on a specific area of the picture.


When you are satisfied with your settings, click the Apply button to modify your picture or selection.
