About the Geometry Tab

The Geometry tab is used to correct lens distortion and perspective, or rotate and straighten images. It is also possible to use the Crop tool to change the composition of the image.

Settings can be set as a preset for future use.

To use the Geometry tab:

1. In the Develop Tools pane, select the Geometry tab.
2. Develop the image by expanding and editing any of the following:

• Lens Correction,
• Rotate & Straighten,
• Perspective,
• Crop, or
• Vignette Correction.

Saving and Canceling

After developing an image, choose from one of the many options for saving the image, depending on the next workflow step.

To save an image:

1. Click Done.
2. Select one of the following:
   • Save: Save any changes.
   • Save as: Save a copy of the developed image with a new name or format.
   • Discard: Discard any changes.
   • Cancel: Remain on the same image in Develop with all changes intact, without saving the image.

To discard changes to an image and return to the previous mode:

Click Cancel.

It is not possible to directly save changes to a RAW file. Changes to a RAW file must be saved as a different file type.

ACDSee will automatically apply geometry corrections to DNG files that include geometric distortion correction tags. DNG files created from the Adobe DNG Converter© will often generate geometric distortion tags for micro 4/3rds cameras.
