Where the Camera Is
One principle governs this entire lesson: perspective is fixed by the position of the camera and by nothing else.
Relative sizes depend purely on subject distance. Magnification scales every element equally, so changing focal length never alters perspective.
| Operation | Perspective | Framing |
|---|---|---|
| Move closer | Changes | Changes |
| Zoom from 35 mm to 85 mm | Unchanged | Changes |
| Crop the negative | Unchanged | Changes |
Common terms are therefore misattributions:
- Wide-angle distortion happens because you stand close to the subject.
- Telephoto compression happens because you stand far away.
The famous dolly zoom used in Vertigo (1958) relies on this separation. A Camera tracks backwards while zooming in. Matching framing across distance is direct: a 50 mm lens at 3 metres requires a 150 mm lens at 9 metres.
Height and Angle
Camera height shapes how a viewer interprets the subject:
- Low angle: the camera sits below eye level, adding authority.
- Eye level: the camera matches the subject, offering neutrality and respect.
- High angle: the camera looks down, placing the subject into surrounding context.
Common pitfall: believing that a lens has an innate perspective. It does not. Changing lenses only alters framing; moving your feet alters perspective.
