Wow! I didn't know ACR had so many options, well, mine doesn't, still fascinating! I learned a lot more about the sliders I do have and when each slider is useful even if I didn't use them for today's edits. You should check out the video Ashley posted if you haven't already. Anyway, here are my edits for this week's shoot and edit.
Straighten and Crop. Fill Color a "rusty" color--masked off the top of the sky. Fill Color a bright blue--masked off of the middle orange part of the sky. Then a levels layer to bring up the blacks but partially masked off of the river and part of the orange part of the sky. Resize and sharpen for web.
I basically did the same with this image, except instead of a levels layer I opened it in ACR to boost the blacks and I didn't mask off any of the rusty layer. Usually I crop to retain my 4x6 ratio, but that crop ratio didn't work with my horizon very well and I actually really like the expansive feel I get from a more panoramic crop.
So there you have it. I'd love to go back again when I have more time to experiment, but in the meantime happy editing! Now I'm off to view everyone else's sunset edits; there are lots of gorgeous photos.
