> If you're using flat media and rectilinear optics, shorter lenses get progressively less and less representative of human vision.
Below ~12mm, yes. 28mm is still a compromise between field of view and usability; even with a 21mm, I have to be right in front of someone for them to fill the frame, because I would have to do the same if I were looking at them with my own eyes.
> This is always true at every focal length. Your choice of composition informs the viewer whether it's a wide angle shot or super-telephoto.
"Lately I’ve been struck with how I really love what you can’t see in a photograph." - Diane Arbus.
Photography, with its receptiveness to stream-of-conscious approach and synchronous rearing with postmodernism, is an inherently subjective medium. Joel Meyerowitz, on his use of wide angle lenses, terms the explicit look-at-this approach as 'collecting' [1]. There are subgenres dedicated to not collecting, introducing ambiguity that invites the viewer to form their own interpretation of the recorded reality.
I took a walk this afternoon and looked at a tree ~5m away. I could visualize framing the trunk of the tree with a 50 or 75mm, but also noticed a child running towards the tree. The childless telephoto perspective would've been a more accurate representation of my subjective experience of focusing on the tree, but an objectively less accurate representation of what I was actually seeing in my field of vision. A tree-only photo tells you to look at the tree, whereas a wider perspective invites you to consider the relationship between the disparate elements. Meyerowitz also waxes poetically about this [ibid].
Again, the Ricoh GR and Leica Q, the most popular dedicated street/documentary cameras, have 28mm lenses, and the Fujifilm X100 a 35mm. Essentially all of the street photographers I've met internationally use either a 28mm or 35mm most of the time. There is a visceral you-are-right-there-in-the-moment feeling from looking at a wide angle photograph, especially when printed large, that simply cannot be reproduced with a normal-telephoto.
