I have this thing about the way photographers tend to think about perspective. All over the web, in books and magazines going back decades you can see things along the lines of:
"Tele lenses flatten the image by compressing perspective. Wide lenses increase depth by expanding perspective".
These errors are another example of confusing correlation and causation and you see it everywhere. Perspective is managed by moving closer or further from your subject, not by changing focal length. Tele lenses do not compress anything, distance does. The reason wide angle lenses give big noses is because you stand too close to the nose in order to fill the frame. The reason why the error persists, I think, is because when you use a tele lens, you photograph things that are far away and when everything is far away it all looks about the same size. And the only time you notice this is when you use a tele. And when you use a wide, your subject is tiny, so you naturally move closer. In both cases it is quite natural to jump to conclusions about causation. And most of the time mis-understanding the cause doesn't harm getting the shot, so it's really a silly thing to get wound up by.
I can't quite work out whether this is also true about the exposure triangle. Does using it make you shoot things incorrectly? Given I don't actually understand what the ISO knob does, it's difficult to be sure.
