As photos taken on your camera or device is not the exact aspect ratio, most print sizes will require some cropping of the photo. This shaded area and dotted line demonstrates where the photos will be cropped and the area that you will receive in the printed product. You can move the shading area to suit your requirements by moving the mouse on your desktop or by selecting the crop photo on your mobile device. Note: If you crop an image, the dotted line and shading will no longer appear and only show the area that is to be printed.
