Question: 1 / 400

How will a film appear if it was unexposed?

Blurred

Dark

Clear

The correct answer is that an unexposed film will appear clear. When a film is unexposed, it means that it has not been subjected to any radiation or light that would typically create an image on the film. As a result, the film remains transparent, showing little to no density. This is similar to how film used in photography appears before it has been exposed to light.

Blurred images typically occur due to movement during exposure or improper focusing, while a dark appearance indicates overexposure, where the film has received too much radiation. Overexposed film is characterized by increased darkness because it has absorbed excess radiation compared to what is necessary for a diagnostic image. Thus, clarity in an unexposed film is due to the absence of any exposure, allowing it to remain clear and transparent.
