Measured

## How it was read

Read by the Visual Analysis Engine, version 23.8, on 2026.10.06: measured by code, then read 5 times by Claude Opus 5.5 against three reference paintings (R1 to R3), each read independent of the others. [How the engine works](https://peteryuill.art/method).

WHAT THE CODE SEES

## Three views of one sheet.

Left, the photograph. Centre, the tone stretch the model is shown beside it: the darkest 45% of tones spread over the whole range, so flat black, banding and stains show. Right, every pixel as the measuring code classes it: cyan black ink, deep teal translucent grey, stone the palest ink, near black bare paper.

![T_381, tone-stretched]

![T_381, classed by brightness]

82% of the sheet carries ink

TONAL STEPS

## 2 families of tone.

Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Two or fewer: Tonal depth is held at the bottom rung whatever the model reads. A dense sheet of many translucent passes can count low here, so Layering is left to the reads. Life inside the black: 0.047 (under 0.045 reads as flat).

FIVE READS

### READ 1, IN ITS OWN WORDS

“A radial-arc S-composition in the vein of R3, but heavier and darker. The fluent, layered upper fan is offset by a dense, near-flat lower mass. The sheet is ordinary overall.”

Form · BUILT

Upper arcs follow the brush's rotation cleanly, with crisp stepped ends. The lower half swells into a heavy slab where the separate strokes are lost.

WEAKEST Bulky, undifferentiated lower dark mass

STRONGEST Fanned arc strokes in the upper head

Tonal depth · MODELLED

Dark interior modulation of 0.047 is barely above flat, with only 2 tonal steps. The upper fan shows graded bands, but the lower mass reads as one dense dark.

WEAKEST Lower-left dark mass, nearly flat in colour view

STRONGEST Graded translucent arcs at top and right edge

Layering · LEGIBLE

Many overlapping arcs stay readable at the top and right edges. In the lower body the passes build up into a single dark where their order is lost.

WEAKEST Stacked passes fused in the lower mass

STRONGEST Overlapping translucent arcs on upper right

Composition · WORKING

The vertical S-movement and the two cut-in white notches give the sheet direction. The heavy lower half fills the frame, so the empty paper is only edge leftovers.

WEAKEST Crowded, heavy bottom half with little paper

STRONGEST S-curve rising through the two white notches

Material and surface · SOUND

The ink is controlled, with clean arc edges. Faint crease and wrinkle lines cross the dark mass, there are scattered drops at top right, and the paper has a beige tint. None disrupts a principal form.

WEAKEST Crease lines crossing the central dark mass

STRONGEST Dry-brush stepped edges of the upper arcs

FLAWS

## 5 distinct places, 0 major.

Each read must name every flaw and where it is, in a ninth of the sheet. Here the reads named flaws in 5 distinct places, 17 mentions in all across 5 reads; the number in each ninth is how many times a flaw was named there. Reads agreeing on a place strengthen the evidence for one flaw; they do not multiply it.

The rating these readings produce, the rules applied and the arithmetic, with Peter's own rating where he gave one, are in [the Archive record](https://peteryuill.art/archive/works/T_381).
