Thank you, everyone, for your input, ideas, and discussion! Majeed, thanks for the clone job. I had guessed at what that would look like, but don't have the tools or time at present to do the work. It was much as I envisioned -- different, arguably better, arguably not, surely a matter of preference. The design is much more pure with the buildings cloned out, but the picture becomes more literally 2D and, I think, visually a little less interesting. I think I personally prefer the original, but I can see the merits of the modified one as well.
That said, I am occasionally accused of experimenting when I am not. This time, I actually am experimenting. This is the kind of picture I "see" pretty regularly, but almost never shoot. I raise the camera to my eye, and then cannot shake the vision of a million casual shooters with iPhones and a moderate sense of design and color shooting it before and after me. Then I shake my head, and lower the camera. Yesterday, I went out with the idea in mind to simply shoot something populist and appealing, to prove to myself that I actually can. Seattle, I admit, was quite wonderful to give me the tree and the light that it did. But I did shoot it and a couple other things quite quickly while carrying my 3 month old around, edited for 5 minutes in Picasa, and threw it up. Luck? Skill? Definitely some of both, and quibbling over how much of each isn't a game I am interested in.
In short: I don't have any problem at all with people liking this thing, it's quite flattering in fact, and I certainly enjoy the approval. This is definitely to the taste of many people, and I mean to take not a single thing away from those people. It's not to my taste. I hate myself a little for taking pictures like this, for personal reasons which I cannot fully explain.
Again, thank you all, both for your criticisms and your approval. I genuinely appreciate it all, as always.
