12.4. Lens & Geometry Tool
This tool is useful for enhancing your image and removing lens imperfections. These sliders are designed to
remove flaws in the image caused by the lens or camera handling. The exact controls you’ll see vary
between standard and raw files.
Auto Distortion Corrections (raw only). Click this option to remove lens distortion automatically.
The filter analyzes your image and its metadata to calculate an automatic fix that you can apply in
one-click. Get rid of wide-angle distortion and get truer perspective lines and more attractive portraits.
Remove Chromatic Aberrations (raw only). Chromatic aberration is a type of color fringing. It often
happens on telephoto lenses and in areas of high contrast. It tends to show up as magenta or green
edges.
Defringe. This adjustment can remove halos or edge noise (particularly in high-contrast areas).
Lens Distortion. Drag to the left to increase the barrel shape of the lens. Drag to the right to pinch
and compensate for wider angle lenses. You may need to crop the layer or use the Scale command in
the Transform controls to compensate for gaps at the edges.
Devignette. Removes any darkening at the edges of an image caused by the lens itself. This is a
corrective command, not a stylizing command. If you want an artistic vignette, be sure to explore the
Vignette filter.
Devignette Midpoint. Refines which areas are brightened or darkened by the Devignette slider.
