Thanks, Nancy and Brandt.
There seem to be no straight walls out here, Brandt, with structures built on simple poured concrete on top of clay that expands and contracts with the seasons. I use t/s and PTLens to get part way straight, but I may just have to accept it.
You are using highly engineered equipment that is designed so that these two-dimensional illusions of space and form show the dihedral edges and outer contours of man-made objects that we "know" to be straight and plumb as straight and plumb. That expensive illusion is more important than adhering to the specifics of the objects depicted.
Additionally, the problem with the Barn picture isn't that the corners of the walls aren't plumb, but that the entire object appears to be distorted in a way that matches the distortion made by less-than-ideal lenses. There is a uniformity to the slumping of the picture-left side of the barn, and that uniformity extends to the other objects and space depicted nearby on the picture plane.
I agree with Brandt that this is a problem that should be fixed, or that a fix should be attempted. The image is worth making a better picture.
The other pictures have — to my eye, obviously — other subtle distortions of space the perception of which detracts from the emotional reaction to the illusion of vastness. I would like to see these both close to airless, and deep — a hard illusion to pull off. Any deformation of the picture plane mitigates their impact. They are wonderful, specific, evocative images — well worth the additional efforts to iron flat the surface wrinkles and fix them hard and fast so the viewer can enter and experience the presence you're creating.
