RAW Corrections

This script lets you access the following features, otherwise unavailable in the PSE-version of the Adobe Camera RAW plugin (ACR):
- correction of lens-specific distortions and vignetting;
- removal of chromatic aberration.

1. Open a native camera RAW (and not JPEG, TIFF, or DNG) file in the ACR plugin window, accomplish the needed adjustments, and click "Open Image" button.

2. Run "RAW Corrections" script that opens a dialog box (fig. 1).

3. To enable the automatic correction of geometric distortions and vignetting, check "Enable Lens Profile" gadget.

4. To enable the automatic removal of red-green and blue-yellow color shifts (lateral chromatic aberration), use "Remove Chromatic Aberration" checkbox.

5. To remove the purple or green fringes (axial chromatic aberration) set the amount and hue values with the corresponding sliders.

6. To enable comparison of the modified photo with its previous version, check "Compare versions" checkbox.

7. Click "Preview" button which reopens the photo in the ACR window.

8. Scrutinize the image preview. If you don't like what you see click "Cancel" button to discard the changes. Or, if you are happy with the achieved result, confirm the changes by clicking "Open Image" button.

In case of "Compare versions" option selected, alongside with opening the RAW photo itself, the script creates an additional document containing "before" and "after" states of the file as separate layers. Thus, you can easily evaluate the correction result by turning the uppermost layer on/off (fig. 2).

Important! The script only works if the ACR plugin saves the image settings to sidecar XMP file. Although this option must be selected by default, please, be sure to check the ACR-plugin preferences by clicking the button in the ACR window.

Note: This script doesn't work with App Store version of Photoshop Elements.
