Perspective & Depth

Back in Week 4 we made a single object look solid by sculpting the light on its surface. This week we go bigger: we make an entire scene feel three-dimensional — like there's real distance receding into the frame, space you could step into. The photograph is still a flat rectangle, but your eye can be convinced otherwise with a handful of reliable cues.

The Cues That Build Depth

Depth is assembled from signals your brain already trusts in the real world:

• Overlap — when one object covers part of another, the front one reads as closer. The simplest, most reliable cue there is.
• Linear perspective — parallel lines converge toward a vanishing point as they recede: roads, rails, hallways, fences. A powerful pull into the frame.
• Relative size — familiar things look smaller the farther away they are, so size becomes a distance signal.
• Atmospheric perspective — distant elements go lighter, lower-contrast, and bluer (warm advances, cool recedes — straight from Week 6). Think hills fading into haze.
• Layering — a clear foreground, middle ground, and background let the eye travel back through distinct planes.

Position and Lens Do the Heavy Lifting

Where you stand matters more than what you own. Getting low and close to a strong foreground element exaggerates the sense of space dramatically — the foreground looms, the distance stretches away. Wide focal lengths amplify this; long ones compress it, flattening the planes together (an effect we'll deliberately abuse in Quarter Four). And selective focus — sharp foreground, soft background — separates the planes one more way.

How Depth Behaves by Frame Shape

"I got down in the dirt and shot through a flower in the foreground, and suddenly my flat field photo had three rooms in it."

In the Edit: Lens Corrections & Transform in Lightroom Classic

Perspective is something you can correct — or shape — in the edit. This week's step lives in two Lightroom Classic panels:

1. In Lens Corrections, enable profile corrections to fix distortion and vignetting, and remove chromatic aberration, so your geometry starts clean.
2. In Transform, use Upright (Auto, Level, Vertical, or Guided) to straighten converging verticals — the leaning buildings of architectural shots — or to deliberately keep them when the convergence is the drama.
3. Watch the edges: perspective corrections crop inward, so leave yourself room when you shoot.

Sometimes you fix the perspective; sometimes the converging lines are exactly the depth you want, and the right move is to leave them alone.
