Can the police enhance the photo to read my plate number after it is overexposed due to PhotoBlocker?
The answer is NO they can not. If the positive image is illegible, the negative image will be EXACTLY as illegible. Merely looking at the negative image cannot improve the legibility of a license plate. If you can’t see the faint dark letters in the positive image, then you won’t see them any better as faint white letters in the negative, or vice-versa. There are certainly ways to enhance the contrast to try to amplify and clarify subtle gradations, but they have nothing at all to do with checking the negatives.
