A clear film can be caused by either no exposure or prolonged fixing. No exposure will result in a clear film because the light-sensitive emulsion on the film was not exposed to any light, therefore no image was formed. Prolonged fixing can also cause a clear film because the fixer solution removes the unexposed silver halides from the film, leaving behind a clear, blank area.
