Cinematography : 16mm Question by Christopher Binder

I know a lot of people that just project the 16mm on a white wall and record it with their HD camera if you have access to a projector it's much cheaper and looks just as good

I'm assuming you're talking about a "still-photo" scanner. If so most of the 35mm scanners I've worked with have available a holder that allows you to put a 16mm (or super-8) clip in. It's basically two (35mm size) thin pieces of glass that sandwich the smaller negative or transparency and hold it flat for scanning.
