Jeremy, It's not a question of "bother." There's no reason to crop it. Square format pictures tend to be static, but this is a situation where static is what you want. Your composition makes good use of the rule of thirds, and the long drop down the rocky slope into darkness enhances the feeling of isolation of the structure (castle?). I suspect this is your first impression of the thing. Did you make any other shots?
Thanks, Russ, and everyone else.
When I wrote "bother", I was really wondering if someone other than me would think that the image was worth fiddling with at all. It meant something to me, because I was there when I took it, but I wasn't sure it would appeal to anyone else.
I didn't make any other shots: that was pretty much the only view from where I was at the time (the veranda of the house where I'd spent the previous night). It's a two-shot stitch, for what that's worth, taken with a 5D2 and a 100-400L at 330mm.
The building is the summer palace in Udaipur. No-one has lived there for many years and it's fallen into disrepair, but it was used for a while as a radio relay station (hence the profusion of aerials). I went up to it that evening to watch the sunset, which was rather lovely.
It never ceases to amaze me when someone shoots a picture of something he saw that stopped him and said, "take my picture," and then proceeds to figure out how he can crop the thing to "improve" it. When you took the picture you were "cropping" a small hunk of reality that exists in the middle of infinity. Learn to trust your own judgment.
You're right, of course. I just have this chronic sense of insecurity...
