But reciprocity breaks down eventually, and it's not obvious to me that the paint will fade at all.

- jrockway 3y agoI think there's a pretty significant amount of UV coming in even through a pinhole. There are indoor-only things that are damaged by UV (old computer cases) even though windows block a lot of the UV. I think what's hard to balance is what effects other things will have. Humidity will get into the camera and the water will attack the paint. Air will be oxidizing the pigments. Bugs can probably get in and eat the paint. 1000 years is a long time! You have to hope that other effects don't destroy the image more quickly than it can be created.
