Drag the brightness, contrast, or color sliders, or enter specific values in the corresponding text box to make corrections. Dragging each slider to the right or inputting a positive number in the text box increases the brightness, contrast, and color. Changes will be reflected in the displayed image and in the graph at the top of the palette. The horizontal axis of the chart indicates the original image values and the vertical axis the new values. Click the reset button to cancel all changes. Clicking the auto-setting button corrects the brightness and contrast automatically without affecting the color balance. Click the reset button to cancel the changes. Is this picture too light? Adjusting brightness and contrast can be more difficult than it looks. The top image looks too bright, especially the mountains in the background. Simply making everything darker with the brightness control creates a muddy image - the snow and sky are a dull gray and there are no strong blacks. By adding contrast to the image, the snow is brightened while the darker trees are accentuated. The extra contrast also gives the image the appearance of being sharper as well as revealing fine details. 34 BASIC IMAGE PROCESSING
