Before digital, most of what I shot was either 35mm SLR 3:2 or 6x7 medium format. With 35mm of course you'd order prints unless you were shooting chromes for slide show. So then the print crop became 3 1/2x5", 4x6", 5x7", 8x10" or some other variant to match standard paper sizes. I printed my 6x7mm on 16x20". So none of the print formats match the film sizes except 4x6" for 35mm. It's like the paper and film manufacturers live in different worlds. Now add to that 4:3 computer screens, 16:9 HDTV screens and a person can really go nuts.
