Camera distance changes portrait perspective more than a crop does
A crop changes framing; moving the camera changes near-to-far relationships.
A close phone portrait can enlarge the nose relative to the ears. Cropping a farther-away portrait to the same frame does not create the same perspective because the camera viewpoint changed.
Separate viewpoint from framing
Perspective is determined by camera position relative to the subject. Focal length changes how much of the scene fits in the frame; a crop can mimic a tighter field of view but does not reproduce the viewpoint of a camera placed farther away.

Test at the booth’s actual seat
Photograph a face from the intended position, then move the camera back and use a longer focal length or crop to restore framing. Compare nose, ears and background proportions. Keep the subject’s pose and expression consistent enough that distance remains the key variable.
Balance perspective with room constraints
A booth may not have room for a long camera distance. Choose the greatest practical distance that still gives comfortable interaction and adequate framing. Avoid describing a cropped close-up as optically equivalent to a portrait captured farther back.
