Thank you to everyone.
Jeremy: your comments are both about things I had not noticed: very useful.
Francois: capturing this colour has been challenging because of the leaves are small and spread out. That rock wall was facing a muted sunset, and is copper ore, hewn by hand, that has been waiting a century to be hauled away. It was stacked neatly so that the volume mined could be measured and the miners paid. I think about this when I think that my job is hard.
Isaac: there was of course a balance in DOF, blurring the green and keeping the fireweed leaves in focus even though they have a lot of depth. I'll revisit the background.
This is very interesting information about mining.
