A Wind / B Wind definition
A film’s emulsion position. A film is printed emulsion against emulsion, and because of this any print made against the original is called an A-Wind. The original from the camera is known as a B-Wind. These are the only possibilities of the positions because there exist just two sides to a piece of film. One can tell if he/she is looking at a piece of A-Wind because the image will read correctly, as opposed to the B-Wind side that will read backwards. If one is going to use the negative from one’s camera, one will need the B-Wind track.
