To view the effects of any changes that have been made and compare them with the original, use the
Processed and Natural tabs in the preview area to switch back and forth between the processed and
original image. The image produced when you click the Scan button to open the image in the host
application will be the same as the image in the Processed tab.
When using Nikon Scan as a stand-alone application, you can use the Ctrl-T (Windows) or -T
(Macintosh) keyboard shortcut to switch between the Processed and Natural tabs.
