Light corona size
Interesting. Never seen such thing. Wonder if this only happens to camera lenses or human eyes too.
Some years ago (early PS4 era), a company showed a nice realtime demo of a orange robot in something like books library environment,
I can not remember the name of the company. They make middleware for game postprocessing fillters.
On their site, they had a very detailed research paper about such lens effects, IIRC.
Oh, found it, just not the paper: https://www.siliconstudio.co.jp/middleware/yebis/en/
Edit: Slides here (not sure if it's helpful): https://www.siliconstudio.co.jp/en/rd/presentations/

This is in case of the first effect. In case of the second effect, in order to see it, if you lack the access to a fog right now, it is said it can be observed through wet(fogged) glasses.
The Yebis ON vs Yebis OFF part of the video looks awesome.
