Eric, That's the problem people have when they don't do their cropping in the viewfinder and hope to improve things in Photoshop. It's damned hard to de-crop unless you screwed up a previous crop.
But I'm not sure Candide could have framed much to the left. That closest arch is essential to the composition, and so is the closest post. I don't know what he was working with. Had to be either a medium format, or else he cropped to a 1 to 1 aspect ratio. A zoom lens might have solved the problem, though the result probably would have required a crop. How's that for an idea you don't see often on LuLa? A required crop!
Thanks for the kudos on the spotlight. It was fun dragging out all that old stuff and cleaning it up. It's hard for me to believe now how primitive the processing facilities were that made those negatives.
