@avogadro@well.com I think distortion from tilting the camera up is mostly a learned expectation from recent times. If you look at architectural photos from 50 or 75 years ago, when fancy cameras routinely supported movements, parallel vertical lines are almost always rendered correctly. It was only after the proliferation of small SLR and rangefinder cameras, which lack movements for correcting this, that tall buildings started tilting backwards.

My photo practice is hipster-retro in that respect.
