Histogram Displays a graphic of the color information levels in the image, based on the selected channel. Click

and drag the line to manipulate the curve. Each time you click the curve, a new node is added. You can

drag the nodes up and down the curve. To remove a node, drag the node up and out of the graph, or

down and out of the graph.

Exposure warning Highlights overexposed and underexposed areas of the image. Overexposed pixels turn red,

underexposed pixels turn green.

Adjusting lighting

You can use the Lighting tool to adjust areas in an image that are too dark or too light, without affecting other areas of the photo.

You can also simultaneously lighten dark areas that are too dark, and darken areas that are too bright. Examples would be a photo of

a person silhouetted against a bright background like the sea, or a window. In fact, most photos taken on a dull day, or with a flash,

can be improved in various ways with fine adjustments. You can save your options as a preset for future use.

The Lighting tool lets you make quick and easy adjustments using three sliders. ACDSee 14 analyzes the photo and varies the

adjustment throughout the image automatically. For example, darker images are brightened more. By clicking the Auto button, you

can have ACDSee 14 fully analyze the photo and set the slider positions automatically. You can also click directly on an area of the

image to generate automatic settings optimal for that area (usually the subject of the photo).
