"If it can be written, or thought, it can be filmed..." STANLEY KUBRIC
A or B Wind
From Encyclopedia PRO
When a roll of 16 mm film, perforated along one edge, is held so that the outside end of the film leaves the roll at the top and toward the right, winding "A" should have the perforations on the edge of the film toward the observer, and winding "B" should have the perfo- rations on the edge away from the observer. In both cases, the emulsion surface should face inward on the roll.
