Part 1 — Selfie: Wrong Way vs. Right Way

Close-up vs. stepped-back + zoomed-in.

Close-up selfie with perspective distortion
Close-up — expected distortion.
Stepped-back and zoomed-in portrait with reduced distortion
Stepped back + zoomed in — more flattering geometry.

Part 2 — Architectural Perspective Compression

Zoomed-in view down a street vs. walking forward with no zoom

Wide angle street scene from closer position with stronger perspective
Closer with no zoom — stronger perspective lines.
Telephoto street scene with compressed perspective
Zoomed in from far away — flattened, compressed look.

Part 3 — The Dolly Zoom

Move the camera back while zooming in (or vice versa), keeping the subject size roughly constant.
