Forensic astronomers date famous photograph

From Yahoo News:

“Autumn Moon, the High Sierra from Glacier Point,” taken by Ansel Adams in Yosemite National Park, is a thrilling view of the American West, featuring a waxing Moon rising over dark, ice-tinged peaks.

But precisely when Adams took the iconic black-and-white picture has never been clear, and dates for it range from the mid to the late 1940s.

A team led by Donald Olson, a professor of physics and astronomy at Southwest Texas State University, claim that the mystery can be resolved.

The linked article includes the details and a copy of the photograph. One interesting fact is that the identification of time, date, and location resulted from the discovery of an original color exposure of the image.

A New Blog

My friends and family will groan but I’m starting another blog here today.

I have two other blogs where I post my photography: dan’s outside
and G Dan Mitchell | Photography.

dan’s outside
is where I post about my outdoor interests so photos posted there reflect these themes. For some time I have been taking other photos that don’t really fit at that site. This new site can accommodate photos on any theme.

G Dan Mitchell | Photography
is where I plan to eventually post the images that I think are my best. However, I often want to post photos that are current but may not ultimately make it to that site. I plan to use this new blog to post lots of images that I want to share but which might not ultimately be posted on the other sites.
