There is no real ‘right’ focal length to simulate the way we see, however a combination of focal length, print size and distance the print is viewed is a factor to consider-
Take the number of you focal length shot on 35mm/full frame (or calculate crop factor to get equivalent focal length), and that is the distance in millimeters to view away from the original 24x36mm shot.
Blow this number up with the photo size, so if you shoot a shot with a 50mm lens (on a full frame camera), and blow it up to 24x36”, you will have the most believable perspective standing from 50” away, creating an almost surreal optical illusion of being within the scene.

best viewed in full. Taken this afternoon on my old TLR, there’s a nifty little story behind getting this shot.
quick-and-dirty scanned by holding film in my hand in front of a flash umbrella, I really need to get on that whole ‘scanner’ thing

part of a recent roll of shots I’m really, really proud of. Hope to get access to a proper film scanner soon so I don’t have to spend a week in the lab perfecting prints only to have my scanner decide it wants to enhance the grain 20-fold
