4. Next, the photographer crops the photo (in this case a 1:1 ratio) and then resizes it for its purpose. I always resize to print, meaning your dimensions should be in inches the size of the biggest print you want of that photo and save that picture size at 300 dpi. If i wanted to print this photo, i would recommend a frame at the very least 8inX8in at 300dpi, however you could go much bigger if you wanted. If you want to post this photo on the web, facebook, or something, you will have to bring the file size below 5 mb. if you were to post this photo on facebook, i would recommend a 4inX4in frame at 300dpi, that should be small enough to bring the file size below 5 mb and the photo will still be printable. But you might have trouble printing anything over an 8inX8in photo.
