[ELI5] How does the flash in cameras damage paintings in museums?
In: Technology
Flashes used to emit a lot of UV which damages dyes and paint. Flashes no longer emit UV so they don’t do any damage.
Museums have kept this rule for two reasons:
1. Flashes are really annoying for everyone else.
2. They have a higher chance of selling their book to you if you can’t take good photos yourself.
