Okay, I have a newb question regarding cropped pictures and photographic prints. Having just shot a bunch of photos, I then went ahead and cropped them without regard for size or aspect ratio. Some are cropped significantly (both horizontally & vertically).
Now I'm wondering what the heck do I do if I want to submit them to Costco for 4x6 or 5x7 prints? Is this something I should have considered before cropping them? What will the print shops do with cropped images?
