The Lens Correction filter fixes common lens flaws such as barrel and pincushion distortion, vignetting, and chromatic aberration. The filter works with 8‑bits and 16‑bits-per-channel images only.
You can also use the filter to rotate an image or fix image perspective caused by vertical or horizontal camera tilt. The filter’s image grid makes these adjustments easier and more accurate than using the Transform command.
You can save the settings in the Lens Correction dialog box to reuse with other images made with the same camera, lens, and focal length. Photoshop saves settings for distortion, vignetting, and chromatic aberration. Perspective correction settings are not saved. You can save and reuse settings in two ways:
Manually save and load settings. Set options in the dialog
box, and then choose Save Settings from the Settings menu . To
use the saved settings, choose them from the Settings menu. You
can also load saved settings that don’t appear in the menu using
the Load Settings command in the Settings menu.
Set a lens default. If your image has EXIF metadata for the camera, lens, focal length, and f‑stop, you can save the current settings as a lens default. To save the settings, click the Set Lens Default button. When you correct an image that matches the camera, lens, focal length, and f‑stop, the Lens Default option becomes available in the Settings menu. This option is not available if your image doesn’t have EXIF metadata.
