Eroding ancient bristlecone pine
Due to the dry high altitude conditions and dense tight-grained resinous wood, the ancient bristlecone pines in this area do not rot; they erode away, over centuries.
A polarizer was used to bring down the brightness of the sky, which has made the sky quite dark: maybe not such a great idea. However, for black and white conversion utilizing the blue channel, this appears to be a very useful idea.
The f/2.8 exposure was given 1/3 stop more exposure than f/4 to ease comparison (thus f/2.8 is actually 1/3 stop darker than shown here). This matches the center brightness closely, though the f/2.8 image is darker away from center.
