I offer professional negative cutting for 16mm and 35mm films and have over 20 years experience.
You may have heard that Kodak has discontinued black leader for negative conforming. I have a good stockpile of 16mm black leader and I can usually get 35mm black leader with some advanced notice.
Negative can be conformed to edited workprint or keycode list. 16mm is always cut onto A and B rolls for absolutely clean cuts. 35mm can be cut onto a single roll (all 4 perf formats except cinemascope) as long as there are no fades or dissolves. If there are fades and dissolves 35mm can be cut onto A and B rolls. I do all the negative cutting myself for superior results and offer discounts for films that I shot. Please contact me for more information about preparing your film for negative cutting and printing.
