Image cropping comes into play when the aspect ratio of your phone or digital camera doesn't match the shape of the printing paper, and that happens quite often! Best case scenario you're shooting in 3:2, meaning the 13 x 18 Photo Prints will be the perfect fit for your images. If you're shooting in 4:3 you will need to crop your photos in the editor before placing your order. It's quick and easy and a great way to focus your images on the subject, making them even more appealing.
