How the number was made

Read by the Visual Analysis Engine, version 23.11, on 2026.10.26: 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.

TONAL STEPS

3 families of tone.

Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Life inside the black: 0.063 (under 0.045 reads as flat).

READ 1, IN ITS OWN WORDS

“A strong spiral of translucent layered arcs, close to R3. Tone and layering are fluent and legible, and the composition carries the eye inward. Small grey drips in the white centre keep the surface at sound.”

Form · FLUENT

Arc strokes follow the spiral's travel from the tight centre coil out to the broad outer bands; edges hold. Some lower-left blocks read a little squared off.

WEAKEST Blocky rectangular slabs at the lower-left spiral edge

STRONGEST Tight inner spiral coil of arcing strokes

Tonal depth · DEEP

Modulation 0.063. The tone-stretched view shows grain, dry-brush and stepped greys inside the dark bands, with a wide grey range from pale to black.

WEAKEST Upper-centre mid-grey band, fairly even

STRONGEST Right outer dark bands with grain and stepped density

Layering · ORDERED

Many translucent arc passes overlap in a readable sequence that builds the spiral's depth, similar to R3, though slightly less clear in the dense upper area.

WEAKEST Dense upper-left overlaps merge somewhat

STRONGEST Translucent stacked arcs on the right half

Composition · COMMANDING

The off-centre spiral drives movement from the outer bands into the coil. The white eye is shaped and the two top-left diagonals counter the mass; the left paper is a little passive.

WEAKEST Empty left third, held only by two diagonal strokes

STRONGEST Spiral pulling the eye into the white centre

Material and surface · SOUND

The ink is controlled and the dry-brush is used. Small grey drip spots sit in the white centre, there is a faint curved mark in the lower-right grey block, and specks at the left edge. The red drops are deliberate colour.

WEAKEST Grey drip spots in the white centre

STRONGEST Dry-brush grain at the arc edges

FLAWS

4 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 4 distinct places, 13 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 ARITHMETIC

V23 rating 9.0.

Engine v23.11, 5 reads. Fixed arithmetic, the same for every painting; the constants were set on 24 randomly chosen paintings so the median sheet scores 5. The scale is relative to this archive, not to painting in general, and a difference of less than half a point between two paintings is noise.
