Comparing Images

You can select an image against which to compare other images in your project or in the library. The selected image remains on the screen as you select and display other images to compare against it. The comparison feature is useful for making final selections of the best images in a series or comparing two versions of an image for correct exposure or highlights. When comparing images, you can apply ratings and keywords and make adjustments to selected images.

Comparing images involves setting a “compare” image and then viewing other images against the compare image.
