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

V7
5
From an earlier engine (V7). 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

5 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: 0.030 (under 0.045 reads as flat).

FIVE READS

Five reads, agreeing on 3 of 5 qualities.

Each quality placed on its ladder by each read, and the mean the engine keeps. Where reads differ, they differ by one rung; close calls resolve down.

READ 1, IN ITS OWN WORDS

“This is a confident arc composition in the family of R3, but it has fewer passes and its dominant black band is flat inside. The sheet is sound and ordinary overall: it works without standing out.”

Form · BUILT

Arcs follow the sweep of the brush and hold their walls. The lower black band is a heavy slab, though, and its left ends are cut off bluntly.

WEAKEST Bulky dark lower arc with blunt squared left end

STRONGEST Upper grey arc's dry-brush tail, top left

Tonal depth · MODELLED

The upper arcs show banding and stepped greys, with 5 tonal steps. The interior of the main dark arc is flat (modulation 0.030); tone changes only near its edges.

WEAKEST Flat interior of lower black arc

STRONGEST Banded grey upper arcs, top right

Layering · LEGIBLE

Two or three translucent arc passes stagger at the left ends and lower centre and stay legible. The dark band mostly covers what lies beneath it.

WEAKEST Dark arc covers earlier passes beneath it

STRONGEST Staggered translucent arc ends at left

Composition · WORKING

A single fan sweep carries the eye from the left up and down to the bottom right. The paper under the arc is shaped, but the ink covers 84% of the sheet and the top is crowded.

WEAKEST Crowded upper half with little breathing paper

STRONGEST Sweeping arc movement left to bottom right

Material and surface · SOUND

The ink is controlled. Small spatter drops sit on the paper at the left, away from the main masses, and paper creases show only faintly. No tide lines in the dark masses.

WEAKEST Stray drips near left arc ends

STRONGEST Dry-brush streaks in upper arc edges

FLAWS

3 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 3 distinct places, 11 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: 2 principal ink masses traced (cyan), 4 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 16 edge segments, 13% crisp, 38% soft or bloomed, 50% broken.

THE ARITHMETIC

V23 rating 6.5.

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.
