I completely understand the objections to the out-of-focus beam. I can't disagree, but I find it reproduces the feeling of being there, but then, I was there. Cropping just below the beam makes me want to crop off the left-hand window and perhaps shave a balancing morsel off the right.
A smaller aperture would have helped, but with Foma, one has to make compromises. (Three minutes was barely adequate.) I could have set up the camera using a smaller aperture and gone off for lunch. And why not? It's a private location. Well, the light would have moved and I didn't wholly trust the footing of the tripod...Tilting the front standard up would help the beam, but lose sharpness on the seats. A wider lens, perhaps, but I didn't have one. The same for a smaller format.
I'd be grateful for alternative solutions.
An autobiographical addendum. One of the things that drew me to large format was the nature of the out-of-focus parts of the image. I was loaned an MPP to do a particular job, and seemed to spend more time watching the plane of un-focus rippling through the image as I turned the knob, than I did taking the picture itself. Although we generally strive for pin-sharpness all over, blur is another resource in our tool-box.
Elsewhere on this forum we have been discussing out-of-focus backgrounds. Why not foregrounds, too? I am asking, rather than making a rhetorical point. I'd like to know.
