I am often asked, "I downloaded my images and ordered an 8x10 but my son's foot is cut out of the picture! What happened?" This is called aspect ratio. Most professional photographer's will be using a DSLR with a 3:2 aspect ratio which will provide you a print whose long side is 1.5x's longer than its' short side. So this means in order to keep your image framed just as you view it on your screen your prints will have to maintain their 3:2 aspect ratio, or rather, be printed at 4x6 inches, 6x9 inches, 8x12 inches, and so on. Given the space and lens some photographers will shoot wider so there is more wiggle room for cropping. Otherwise keep in mind that when you are printing that 8x10 or 16x20 you are ordering an aspect ratio of 5:4 and will be loosing a portion of the image. If you think your image looks "funny" when you crop your image, use your photographer! S/he can help you reframe the image in an eye pleasing way.
