For more details about color aberration and how to remove it, see New Color Fringe Correction Controls in the
Lightroom Journal.
Remove red-green and blue-yellow color shifts
❖ Select the Remove Chromatic Aberration checkbox.
Remove global purple and green fringes with the eyedropper
1 Click the eyedropper tool in the Color Corrections Color panel.
2 Press the spacebar to pan and zoom into the fringe area. (Setting your default zoom to 2:1 or 4:1 helps you view the
fringe colors.)
3 Click purple and green fringe colors.
The sliders are automatically adjusted for that color. If you click a color outside of the purple or green hue ranges,
you’ll see an error message.
The end of the eyedropper will change to purple or green if the color under the eyedropper is within the purple or
green hue ranges.
Remove global purple/magenta and green fringes
❖ Adjust the purple and green Amount slider. The higher the amount, the more color defringing.
Take care not apply an adjustment that affects purple or green objects in your image.
You can adjust the purple or green hue range affected by the Amount slider using the Purple Hue and the Green Hue
sliders. Drag either end point control to expand or decrease the range of affected colors. Drag between the end point
controls to move the hue range. The minimum space between end points is 10 units. The default spacing for the green
sliders is narrow to protect green/yellow image colors, like foliage.
Note: You can protect edges of purple and green objects using local adjustment brush. See Remove local color fringes.
Press the Alt/Option key as you drag any of the sliders to help visualize the adjustment. The fringe color becomes
neutral as you drag to remove the color.
Remove local color fringes
Local brush and gradient adjustments remove fringes of all colors.
Note: For best results, perform any Transform lens corrections before applying local color fringe adjustments.
1 Select the brush or gradient tools and drag in the image. See Apply local adjustments .
2 Adjust the Defringe slider. A plus value removes the color fringe. Minus values protect image areas from defringing
that you apply globally. Minus 100 protects the area from any defringing. For example, applying a strong global
purple defringe may desaturate or alter edges of purple objects in your image. Painting with Defringe -100 over
those areas will protect them and keep them at their original color.
Note: Local defringe is available for Process 2012 only.
Correct image perspective and lens flaws manually
Transform and vignette corrections can be applied to original and cropped photo edges. Lens vignettes adjust exposure
values to brighten dark corners.
1 In the Lens Corrections panel, click Manual.
