Well, this was an excellent challenge. Thank you all to everyone who participated. I was really glad to see the level of interest in this contest and the shot.
More than 2/3 of these images would all be worthy of taking the prize. You guys really rose to the task of editing this image. In the end, this came down to a decision based on really nit-picky details and technical aspects. Your artistic decisions, be they involving a frosty Godzilla, image reflections, blurs, or whether you wanted the trees to look like autumn or summer trees were all really good and so no creative choice swayed my decisions one way or the other.
I picked three that I think captured the highest grade of post-processing acumen, stayed loyal to the rules of architectural photography (key in here was the verticals being vertical), retained the sunset coloration and general lighting characteristics, and did not have sharpening halos around the tree. The halos were very hard to mitigate in this image.
But first, here was what I did with the image back in November:
Significantly darker and muddier than the entries here and, were I to do it again, I'd take more control over the shadows and make the details and colors pop a lot more. So, I think that most every submission was a better edit in many ways than my own. Iruggeri, you were close to this but with better color quality.
So what I did to judge these was I opened the ten best in their own tab so that I could compare images without knowing who made them or seeing them in the context of other images. I kept going through them all until I was down to the last three.
Third: Thank you, Todd.
Second: Thank you, Arizona Dave
First: Thank you, quh86
I will say that for the first and second, it basically came down to a con flip. Even though the winner didn't have the sunset coloration, the trees on the bottom right kept their leaf detail and I think that was the hardest part of editing this image.
