Curves options

Specifies the color channels to adjust.

Show Histogram

Toggles the histogram display on and off.

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.

You can use the Edit Brush to paint this effect onto specific areas of your image.

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 settings as a preset for future use.

The Lighting tool is very versatile. There are 3 tabs, each allows you to achieve results in different ways. In addition, there are

several keyboard and mouse shortcuts that allow you to make adjustments on specific areas of the photo itself.

Basics tab: Is for very quick and easy adjustments using three sliders. ACDSee Pro 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 Pro 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).

Light EQ tab: Works like a sound equalizer but with light. You can adjust the brightness and contrast of different tone

bands (areas of relative brightness or darkness) of the image independently using a slider for each tone band. A graph

shows the amount of brightening or darkening applied throughout the tonal range. The gray areas in the graph are

suggested boundaries for adjustment to avoid clipping and loss of detail, and turn red to indicate where you have adjusted

the sliders far enough to cause clipping.
