The Tone tab on the Tools panel lets you access controls that let you fine-tune image tone. All the tools are organized in the Exposure section.
Exposure
The Exposure section combines all the tonal adjustments into a single area. Many of the same controls can be accessed by clicking the Standard tab.
| • | AutoLevel — examines the tonal range of your image and sets the black and white points to be at points such that a fixed percentage of the image will be pure black and pure white. There are two edit boxes in AutoLevel: the left box sets the percentage of the image to be set to pure black and the right box sets the percentage to be set to pure white. |
| • | Blacks — controls the black point in the image. Values lower than zero remove black from the image; values higher than zero darken the image. |
| • | Exposure — adjusts the overall brightness or tone of the image |
| • | Highlights — recovers highlight details and color from overexposed portions of your image. |
| • | HR Range — controls how much of the image is adjusted by Highlights. Lower numbers recover detail and color from only the lightest areas; higher numbers expand the recovery to a broader range of light areas. |
| • | Fill Light — recovers shadow details by selectively brightening only the darkest portions of your image |
| • | Fill Range — controls how much of the image is adjusted by Fill Light. A small range adjusts only the darkest image areas; a large number brightens more of the midtones. |
| • | Contrast — controls the difference between the lightest and darkest areas of an image. Increasing the contrast makes the dark areas in the image darker and the bright areas brighter. |
