After hoping for the right conditions for some years, it all came together Thursday at sunset. The fall is very ephemeral, depending on melting snow of top of El Capitan (in Yosemite NP) and the sun angle is only optimal for about a 10 day window. Light depends on clear skies to the west as far as well off the coast south of San Francisco Bay.
For details on the situation, see Michael Frye's blog -- he has been a preeminent Yosemite photographer for 30 years. http://www.michaelfrye.com/landscape-photography-blog/. He shot from a different location -- I was at the one he calls the Galen Rowell view. Scroll well down the page to the Post Archives for several recent articles on it.
Canon 5D3, 100-400 II at 188, f/5.6, ISO 800. Very basic LR work and into PS only for a very slight cloud cleanup along the left edge and Nik's Dfine -- hardy needed but why not.
