I offer two print sizes in one package, 8×12 and 4×6. You can do the math, it’s the same ratio of 2:3. That means when you get the prints in either size, nothing is cropped and nothing is missing. You are getting everything you see. If you decide to get 8×10 photo, you have to crop 2 inches off, that’s 16.66% of the image you are losing, and it becomes a 4:5 ratio.
I will apologize in advance for all photographers who do not mentally think about a 4:5 ratio in their viewfinder while busy shooting a hectic wedding day. In the worst case scenario where you happen to buy an expensive custom frame that is in the incorrect ratio, I can always do some Photoshop magic and shrink the photo to fit a 4:5 ratio and reconstruct the missing edges with the clone tool. That is if you don’t start the message with an angry and demanding tone of voice telling me I owe you a completely new set of photos.
