Aspect Ratio: The relationship between the width of an image to the height of an image, typically express as Width:Height. For example a 4 x 6 image has a 3:2 ratio; a 5 x 7 image has a 7:5 ratio; and an 8 x 10 has a 5:4 ratio.
Cropping: The removal of part of an image to improve framing, accentuate the subject, or change an aspect ratio.
Understanding crop ratio’s is part of the job as a photographer but most clients don’t speak that same language which leads to receiving prints that aren’t cropped right, yikes! All of my photos are shot in a 3:2 ratio because the most common print size is 4x6. However many clients want photos in a variety of sizes, not all of which fit the 3:2 ratio. The image to the right is an example of a photo I shot in 3:2 ratio. It shows what the crop would be for some of the most common print sizes. Be sure to adjust your crop before you order your prints! You don’t want to cut someones forehead off accidentally. Most photos when cropped is minimal to the composition of the image but not all so be careful when cropping to a certain size. Sometimes an image just can’t be cropped to say like an 8x10 without cutting something off. In those cases I suggest printing in a 3:2 ratio size (like and 8x12 instead of an 8x10) and then either shop for an 8x12 frame or get a larger frame and have it matted.
