Tone from line

The etcher's value scale: each layer of hatching crosses the last at a new angle. Paper, one layer, two, three, four. Every shadow is a counted number of layers.

An etcher cannot press harder. Every line is the same black, so every value is a count: bare paper for the lights, one layer of parallel hatch for a light halftone, a second crossing it at about sixty degrees for halftone, a third at a shallow angle for shadow, a fourth for near-black. Keep the spacing even within each layer and the line weight constant, and the layers add up to a clean scale.

Working this way with a pencil is the best training for the Line half of the course because it forces decisions. Before you hatch a wall you must decide its value, and therefore how many layers it gets, and therefore where it sits relative to every other plane. Meryon's Notre-Dame is this discipline carried through an entire city.

A practical sequence for a building: lay one layer over everything in shadow. Lay a second over everything in deep shadow. Lay a third only in the openings and under projections. Then stop and squint.

Pitfalls

What

Layers crossed at ninety degrees.

Why

A grid reads as a screen, not a tone.

Fix

First layer at 45, second at about 105, third near horizontal.
