hat happens to your film at the lab depends partly on you since what the lab does to your film will be determined largely by the instructions you send. The receiving section at the laboratory is a very important division. They prepare the work order or job order that will accompany your film during its stay at the lab. If the person who opens your package at the receiving desk has to pull out a crystal ball in an attempt to find out what to do with your film, then the chances are that you will receive something other than what you wanted. So be sure and supply complete instructions. Most laboratories have instruction sheets to help you supply this needed information. Information needed by the lab is also outlined in the ACL (Association of Cinema Laboratories) Handbook.
