Film Term:
Cloth tape specifically for use on film shoots, much like gaffer’s tape. Camera tape is typically 1 inch wide and white so that it can be used together with a sharpie for labeling magazines with the emulsion type and camera roll number. It is valid to use the terms gaffer’s tape and camera tape interchangeably (they are both really the same type of tape) depending on how the tape is being used. It is designed not to leave a sticky residue behind on the camera.
