20 minForeground trees and walls, then houses, then the city, then the water, then the far shore: five planes, each clearly in front of the next, each a step lighter.

Checklist0 / 1 - 2
Find five
20 minWith the viewfinder, move until your subject gives you five overlaps: something in front of something in front of something. If it only gives three, move your feet or change the crop. Thumbnail it with each plane a distinct value.
FigureFive planes, each in front of the next. Checklist0 / 1 - 3
Draw and grade
20 minFull sheet. Lay the planes from the back forward, each overlapping the one behind, each darker and sharper than the one behind. Make each overlap unambiguous: the near thing clearly covers part of the far thing. Detail in the front plane only.
Checklist0 / 1 - 4
Self-check
5 minTick each item honestly. If one is a no, the session is not finished; go back to that step.
Checklist0 / 3
What it should look like
- A drawing with undeniable depth made from overlap and value, with no two planes touching edge to edge.
Where it goes wrong
- Planes that touch without overlapping. Ambiguous depth. Shift something so it clearly covers part of what is behind it.
