The V23 rating runs from 1 to 9, with 5 the middle of this body of work. It is the engine's reading, and the reference the archive is measured against.

Older engine

V10C
9
From an earlier engine (V10C). Its scale differs from V23's, so it is only ever compared with other readings by the same engine.

How the number was made

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.

TONAL STEPS

4 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: 0.036 (under 0.045 reads as flat).

READ 1, IN ITS OWN WORDS

“A radial fan of layered translucent bands, similar to R3 in its layering. The flat dark right sector, the flat dark interiors and the heavy coverage keep form, tone and composition ordinary.”

Form · BUILT

The radial bands follow the brush's travel and their edges hold. The large right-centre sector is a bulky filled wedge, stiffer than the rest.

WEAKEST Flat, slab-like dark sector at right-centre

STRONGEST Radiating tapered bands in the left half

Tonal depth · MODELLED

The overlapping bands give stepped greys and grain, but the measured dark modulation of 0.036 is flat. The right sector and the bottom-left black are flat inside.

WEAKEST Uniform dark interior of the right-centre sector

STRONGEST Stepped translucent greys in the upper-left bands

Layering · ORDERED

Many translucent passes overlap in a readable order across both fans. Their edges stay visible and build depth, much as in R3.

WEAKEST The right sector covers the passes beneath it

STRONGEST Stacked translucent band edges, upper left and right

Composition · WORKING

The radial fan drives the eye outward from the bottom-centre void, and the top-right paper is shaped. Ink coverage of 0.89 crowds the sheet, and the right slab is heavy.

WEAKEST Dense, crowded lower right and lower left

STRONGEST Radial burst around the white semicircular void

Material and surface · SOUND

The ink is controlled and the dry-brush ends are used well. Small white scratches or flecks sit inside the right-centre sector, with stray specks near the top centre. All are minor.

WEAKEST White flecks inside the flat right sector

STRONGEST Dry-brush band ends and grain, upper right

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.

GEOMETRY

Measured from the 16-bit master.

The previous engine (V22) measured this sheet's master file: 3 principal ink masses traced (cyan), 8 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 24 edge segments, 83% crisp, 17% soft or bloomed, 0% broken.

THE ARITHMETIC

V23 rating 6.7.

Engine v23.8, 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.
