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.
2 Under Transform, adjust any of the following:
Distortion Drag to the right to correct barrel distortion and straighten lines that bend away from the center. Drag
to the left to correct pincushion distortion and straighten lines that bend toward the center.
Vertical corrects perspective caused by tilting the camera up or down. Makes vertical lines appear parallel.
Horizontal Corrects perspective caused by angling the camera left or right. Makes horizontal lines parallel.
Rotate Corrects for camera tilt. Uses the center of the original, uncropped photo as the axis of rotation.
Scale Adjusts the image scale up or down. Helps to remove empty areas caused by perspective corrections and
distortions. Displays areas of the image that extend beyond the crop boundary.
Constrain crop Constrains the crop to the image area so that gray border pixels are not included in the final photo.
3 Under Lens Vignetting adjust either or both of the following:
Amount Move the Amount slider to the right (positive values) to lighten the corners of the photo. Move the slider
to the left (negative values) to darken the corners of the photo.
Midpoint Drag the Midpoint slider to the left (lower value) to apply the Amount adjustment to a larger area away
from the corners. Drag the slider to the right (higher value) to restrict the adjustment to an area closer to the corners.
