Comparing images

You can use the Compare Images feature to compare a group of images. The tool highlights both the similarities and the differences in the properties, metadata, and pixel intensity levels of images you select. You can save your preferred images to a new location on your hard drive, or tag images you would like selected in Manage mode, and then delete, move, rename, or alter the images.

To compare images:

  1. In the File List pane, select the images that you want to compare.
  2. Click Tools | Compare Images. Up to four images display in the Compare Images Viewer.
  3. To change which image displays in the comparison view, do one or more of the following:
    • In the Comparison List, right-click an image and click Send to Active View (indicated by a pale box).
    • In the Comparison List, drag an image to a box in the Compare Images Viewer.
    • In the Compare Images Viewer, right-click an image and click Next Image or Previous Image.
    • In the Compare Images Viewer, right-click an image and click File | Remove From View or click the Remove icon in the image toolbar.
  4. To tag images, do one of the following:
    • In the Comparison List, click the check box that is located at the bottom of the image on the right side.
    • In the Compare Images Viewer, right-click an image and click Tag or click the Tag icon in the image toolbar.
    • Click the Tag All button in the bottom left corner to tag all of the images, or click Untag All to untag all of the images.
  5. To rate images, right-click an image, click Set Rating, and then select an appropriate rating.
  6. To categorize images, right-click an image, click Set Categories, and then select an appropriate category (or create an appropriate category).
