Happy Birthday, Linus

Today is the birthday of Linus Torvalds. That is all.

Thanks to a tip from a reader, for this one.  A photographer named Sergei Mikhailovich Prokudin-Gorskii (1863-1944) made glass negatives in the early 1900’s that could be used to create color images.  He did this by inventing a camera that would take three different frames of the same scene, with different color filters (red, green…

Gone Hiking

Visiting with Kevin, went hiking in Soledad Canyon.  The light was crazy, alterating between awful for photography, and interesting, but always challenging.  When it stopped snowing and the wind wasn’t blowing me around, I was able to get some decent pictures.
