Aside from your ever-brilliant compositions, and master's touch with exposure, your camera is also doing you great service with it's AWB. I find that if I don't set a custom white balance, I probably have to adjust 25% or more of my photo's color - basic color cast corrections. Yours seem invariably spot-on.
Thank you. There's a lot we can do, IMO, before we press the shutter... such as limiting the colour palette, letting the light dictate the kind of photographs we take and working with the limitations of our equipment. So PP is just a tweak here and there... rather than damage limitation! As for exposure... I generally take a shot with my chosen values (aperture and shutter speed), and then bracket two more shots: one over, one under, by changing the shutter speed. The best exposure is usually the middle one, but not always... and I'm glad to have a choice when I'm editing pix back home.
Great shot, very appealing... and I like the black & white treatment...
I do a lot of stock photography, and this is the kind of thing that sells (better than pretty landscapes, anyway). I heard on the radio that we still have hundreds of places where pedestrian pathways cross railways, with no 'safety features' except a warning sign. So I set up a shot in time for the next train...
