User Guide
Look at the preview image as you move the slider to the left or right. If you’re adjusting red/cyan color fringing, you
can hold down Alt (Windows) or Option (Mac OS) to hide the blue/yellow color fringing. Similarly, hold down Alt
(Windows) or Option (Mac OS) while adjusting the blue/yellow color fringing to hide the red/cyan color fringing.
Your goal is to reduce the color fringing as much as possible.
To compensate for lens vignetting
Vignetting is a lens defect that causes the edges, especially the corners, of an image to be darker than the center.
1
In the Lens tab, move the Vignetting Amount slider to the right (positive values) to lighten the corners of the
image or move the slider to the left (negative values) to darken the corners of the image. You can also enter values in
the Vignetting Amount text box.
2
Move the Vignetting Midpoint slider to the left (lower value) to apply the Vignetting Amount adjustment to a
larger area away from the corners, or move the slider to the right (higher value) to restrict the adjustment to an area
closer to the corners. You can also enter a value in the Vignetting Midpoint text box.
Calibrating color in camera raw images
To remove a shadow color cast in camera raw files
Sometimes a color cast remains in the shadow areas after you adjust the highlight white balance using the Temper­
ature and Tint sliders. The Calibrate tab has a Shadow Tint slider to correct this remaining shadow color cast.
❖
In the Calibrate tab, move the Shadow Tint slider to remove the color cast in the shadows. The camera’s sensor and
the white balance affect which colors are adjusted. Usually, moving the slider to the left (negative values) adds green
to the shadow areas, and moving the slider to the right (positive values) adds magenta.
To adjust the rendering of non-neutral colors in Camera Raw
Sometimes colors rendered by the Camera Raw plug-in do not look as expected. The cause may be a difference
between a camera’s profile and Camera Raw’s built-in profile for that camera model. Alternatively, the photo may
have been taken under nonstandard lighting conditions beyond the compensating range of the Adobe Camera Raw
plug-in. The Calibrate tab has Hue and Saturation sliders to adjust the settings for Camera Raw’s built-in camera
profile to render non-neutral colors differently. You can also specify whether to use the profiles built into Camera
Raw or a profile built into the file itself.
1 In the Calibrate tab, choose a profile from the Camera Profile menu:
ACR 3.0 Uses the built-in camera profile of Camera Raw 3.0 for Photoshop CS2 and Adobe Creative Suite.
Important: The options that appear in the Camera Profile menu depend on whether a camera raw file has a profile
embedded or whether it has been processed with a previous version of Camera Raw. Often, the Camera Profile menu
only contains the ACR 3.0 option.
