Kinda old news...
I remember working on a project in the mid 80's. One of the guys wanted to take a picture of the PC board we had. At the time we had the EPROMS covered in a white paper sticker. A flash on the camera glitched it. We changed to silvered stickers and the problem went away.
Lesson learned. Semiconductors are light sensitive. Thankfully the effect is transient, and after a reset all was well with the world.
