Lookout Mountain, facing east, away from the sunset. Sigma 24mm f/1.8 at f/10, ISO 800, 6D, hand-held, 1/60. A few tweaks in LR, cropped toward the bottom of the frame in 16:9 aspect because it suited the composition. The unaltered RAW looked very gray and dull (especially on the computer), moreso than it looked to my eyes. This is slightly richer in the sky than it looked to my eyes, but I like how you can see some deep red in a narrow band toward the horizon, besides the reds on the clouds closer to the camera. I like that this has so much color, yet I am 180 degrees away from the sunset. Probably would have been better at f/8 or f/9.
This Sigma lens doesn't really have vivid color or contrast, but I think it's a good overall compromise at its price point...and its a macro, with AF.
