Cropping
This page is to explain the cropping of images for print {And then to ideally become framed}. It’s all explained by math and aspect ratios and things I don’t feel like getting into, but basically your photos will need to be cropped in some way if you were to choose to print them any size besides the first photo displayed below!

These images are to help illustrate my point and to help you understand what I’m talking about. They are the most common ratios and how each one will look different, depending on that ratio.
