Here's yet another shot from the old Santa Fe Railroad Maintenance Shops
This a 5 panel stitch shot with an 18mm lens. Photoshop can't even think about stitching this baby, but PTGui handles it in stride. The nearly 180 degree FOV looks almost tame thanks to PTGui's "Verdutismo" projection. The price is that the vertical dimensions for the image at extreme left and right are stretched almost 2 times more than the center of the image, but as far as I know it's currently the best available option for super wide architectural shots. I feel the residual curves lend a certain Art Nouveau quality to the image that is in great contrast to starker, narrower but straight-lined rectilinear interpretations. Another hour spent stamping out of cigarette butts, pigeon feathers, and graffiti, and I'm done.
Back in the day, one chugged one's steam engine onto the two rails straddling the ditches for a tune up or whatever. There are something like 16 such stations in this building. Giant machine tools occupied the opposite side of this building.
