Today Sharing : If you wonder when print 8R or 8RW what is the difference? For R are used mostly in Film format where RW is more for digital format. If you have print photo in 4R size,you'll notice they will crop your picture out. If you need a full print without cropping always go for RW print. available size in 10/12/16/20/24RW.
