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.

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.

Black 78%Grey 18% SHARE OF THE INK, NOT OF THE SHEET
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

Five reads, one answer.

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.
