Whats that called, when photos fade because of light?

[KingNothing]

I think it might have the roots "auto" or "photo" in it. Thanks.

if it is a photo of a plant I think it is called: chlorophell

Are you talking about fading of the photo on paper, or overexposure?

[Astronuc]

'Photo deterioration' is a general term which applies to all degradation processes, which could include fading by exposure or oxidation.

A photograph may fade by exposure to air, moisture/water, light, or some chemicals.

Films that are not properly 'fixed' could experience image fading over time.
