While Glenn has been busy photoblogging with modern digital cameras, TangoMan at Gene Expression is blogging about the century-old color photographs of Sergei Mikhailovich Prokudi-Gorskii, "Photographer to the Tsar."

I didn't even know that there was a color-photography process as early as the 1900's and 1910's. But there was, and TangoMan links to the page explaining how three different grayscale images were taken with blue, green, and red filters and then projected onto a screen using the same three filters. (Commenter Jesse also points to these links on "autochrome" technology).

Laws of physics being what they are, it shouldn't be surprising that similar filtering and combining techniques are being used to beam us color pictures from the surface of Mars one century later.

I just had to use that title after seeing this at Reason's Hit and Run blog.

"There are some who call me. . .Timothy?"

Sorry there, er, Timothy, for calling you "Tim" in all of my previous posts. Didn't mean to presume anything, Timothy. (Though to be fair, you did have that Python quote up on your blog when I first linked).

Just please don't presume to call me "Johnny."

Your circuit's dead
Is there something wrong
Can you hear us Professor Hall?
Lots of interesting space-related news over the last month. Your commentary would be welcome. No pressure, of course. Just curious.

James Lileks has dropped several hints over the years that he is obsessively neat. This man color-codes his recovery disks, organizes his canned foods, buys special containers from Target for his refrigerator, and so on. Still, the picture of his study in today's Bleat reveals a surprisingly spartan workplace.

My desk looks like that maybe twice a year (for the 5 minutes it takes me to dust and polish it before returning the piles of papers to their normal resting places).
