On the left side of the page is a scrollable pane containing small images. The first image of the pair represents an original photo; the second image shows how  the original photo was either enhanced or used to create a new composition using digital techniques.  To see the effect click on the first - then the second image (it may take several seconds for the new image to load).                          

To view this information again, click on the ‘Show Gallery Info...’ button which will appear just above the larger image.
