Clapper loader

A clapper loader or second assistant camera (2nd AC) is part of a film crew whose main functions are that of loading the raw film stock into camera magazines, operating the clapperboard (slate) at the beginning of each take, marking the actors as necessary, and maintaining all records and paperwork for the camera department. The name "clapper loader" tends to be used in the United Kingdom and Commonwealth, while "second assistant camera" tends to be favored in the United States, but the job is essentially the same whichever title is used. The specific responsibilities and division of labor within the department will almost always vary depending on the circumstances of the shoot.[1]

Clapper loaders have a very important role as practically the only people on set who directly and physically oversee the state of the undeveloped negative. The loader - the only person who actually handles the negative between the manufacturer and the laboratory - thus can easily render an entire day's work useless if the film is handled improperly. Additionally, the loader usually controls all records with regard to the film stock - from when it is received until when it is sent out to the lab; if this information is miscommunicated or missing, this too can destroy an expensive shoot. Furthermore, the loader usually has much more to do in addition to these tasks.[2] Noted director of photography Oliver Stapleton has written on his website:

The LOADER loads the camera, oddly enough, with film made by either Kodak or Fuji. Loading may not sound like much of a job, but in actuality it is very important. If the wrong film is in the camera, or if it gets loaded twice, or lost, or put in the wrong can, then the scene which corresponded to: Scene 56 - The Army advanced over the hill, the jets dropped their bombs, and the volcano erupted... could be lost. When this happens the Loader can become deeply unpopular very quickly. Kubrick fired one loader I know on his first day of work for walking across the set holding a magazine upside down. Not Kubrick’s first day of work - the Loader's. This was a trifle harsh, but there is a right way to do the job, and the rules are there for a very good reason. If you screw up the minimum cost is about $20,000 and the max any figure you might care to imagine.[3]
