ACDSee Pro 3 User Guide
You can use the lighting tool to adjust tone levels in an image that are too dark or too light, without affecting other areas of the
photo. Tone level is the average brightness of a pixel and its surrounding pixels.
You can also simultaneously lighten dark areas that are too dark, and darken areas that are too bright. Examples would be a back-lit
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 using the lighting tool.
You can save your options as a preset for future use.
To reduce lighting in your image:
1. In Process mode, click Develop.
2. In the Develop pane, select the Tune tab.
3. In the Lighting group, adjust the lighting as described below.
4. Click Done to save your changes and return to the mode you were in previously. Or click Save and select from the drop-
down list:
Save as: Saves your changes, with the option of saving your file with a different name and file format.
Export: Exports your image with all your edits applied to a specific file format and resolution.
Copy to clipboard: Copies the edited image to a clipboard.
You can also click Cancel if you want to discard your changes and return to the mode you were in previously.
You can right-click a slider to reset it to the default value.
Basic Lighting
Basic is for very quick and easy adjustments using just three sliders.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).
Basic Lighting options

Midtones Drag the slider to the right to brighten or drag the slider to the left to darken midtones.
Highlights Drag the slider to the right to brighten or drag the slider to the left to darken highlights.
Auto Click the Auto button for ACDSee Pro to automatically adjust the lighting in your image.
Light EQ
Light EQ 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.
