Dear Patrons of a certain tier!

I'm working on a very interesting retrobrighting discovery.

In brief the hypothesis is as follows:

• Diffuse sunlight through window glass, plus fluorescent lighting and air oxidation, over the course of years, causes slow yellowing. 
• Bright direct sunlight, over the course of hours, makes the degraded & sensitive material less yellow.

This photo is from putting a keyboard in the sun on just one overcast day. The right half had a cloth over it. Notice how the other half has brightened and de-yellowed?! 🤯

Here's similar results on the Omnibot:



And the Macintosh:



Notice the bottom picture shows less yellow? One day of sun folks, that's it.

They're out to sunbathe again today - see my Patreon Lens clip!

If you have something yellowed I'd like to invite you to just put it outside. Cloud cover doesn't matter. Just keep in it line of sight of the UV-A from the sun.

I'd like to include your results so be sure to take before and after photos in identical lighting (I like to use a hallway with no sunlight interference).

Feel free to share interesting results, and the weather conditions, in the comments below! And thanks so much. Happy "Lightbrighting"!
