410. Why is film ruined when it is exposed to light?
Photographic film chemically records information about the light that it has absorbed. Normally, this light was projected on it by a lens and formed a clear, sharp pattern of the scene in front of the camera. However, if light strikes the film uniformly, the information recorded on the film will have nothing to do with an image. The entire sheet of film will record intense exposure to light and will have no structure on its chemical record.
