I don't know how the designers intended it to work... but I rather expected it do approximate what I see when I shift the front standard of the view camera (or shift the 28mm shift lens on the Nikon)... <several minutes later> ... as I try to write this, I realize that it's more complicated than it first seems... let me back up... When I want to photograph a building and I want the vertical lines on the building to appear parallel, I set up the camera so that the back of the camera is vertical... and then I shift the front standard up. When shifting the front standard up, the shape of the building remains exactly the same. If it was 3 inches by 3 inches on the ground glass before shifting, it will be exactly 3 inches by 3 inches after shifting. When you shoot with the camera back tilted (due to lack of shift available) and you try to fix it in Photoshop using crop with "Perspective" checked, the job is more difficult than a simple lens shift, but it would be nice if the math were worked out to make it happen as if you had simply shifted the lens instead of ending up with a building that's 2x3 inches and then needs to be stretched back to 3x3 inches. <shrug> Is this making any sense? Sorry if this is all completely obvious.
