ADOBE PHOTOSHOP CS2 
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. 
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. 
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.
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.
