Merry Christmas one and all

Just a Merry Christmas message from a pestilence locked down U.K. 

Plus a great link to read over your holiday break: https://ciechanow.ski/cameras-and-lenses/

Cheers

Thanks a lot, Garry, for the link and the comprehensive explanation of this fairly complex matter called light. 

Merry Christmas to you too and stay safe from the pestilence!

And happy holidays to the entire ML community!
