Or, to use an example that I've seen frequently over the past few months, while we were looking for a new house – recessed lighting is circular, so when it looks like an oval…that's distortion.
I would disagree with that premise. It only looks circular when view straight on, from any other angle it, accurately, appears oval. I don't believe this to be distortion as I understand the way we are using the word in this thread.
Sorry, but no. It
is circular, that can be verified empirically with a ruler. If it
looks like something it isn't, that's distortion...by definition. If you take a picture of a 14x14' room, and it looks deeper than it is wide, that's distortion, too.
Not all distortions are aberrations.
Yes but it is circular, not spherical, it is not appearing distorted if not viewed from straight on. Perspective is not necessarily distorting.
I suppose the crux of it is if you consider a natural perspective 'distortion' or not. I agree that ultra wide angle lenses make spherical objects appear oval and that is 'distorted'. I can't agree that a natural perspective that is giving truthful three dimensional information is distorted, a circle from anything but directly on is accurately represented as oval.
If you stand on train tracks and view them going straight off into the distance, natural perspective means the tracks converge to a vanishing point. If that natural perspective is, in fact, 'truthful three dimensional information', train travel would be impossible as every train would derail. The way your eye (or a camera) perceives the world does not change the fundamental spatial relationships of the objects in the world.
The playroom in our basement has recessed lighting. If you stand at one end of the rectangular room, the recessed lighting at the other end will look like an oval, as will the hula hoop on the floor. My 'natural perspective' doesn't alter the fact that those objects are circular. If I turn off the lights, it naturally appears that the hula hoop no longer exists...but trust me, I can still trip over it in the dark.
Perspective – natural or not – is merely a representation of reality. To the extent that it fails to truthfully represent that reality, it is a distortion.
