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
7
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

6 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: 0.066 (under 0.045 reads as flat).

READ 1, IN ITS OWN WORDS

“An R2-type gestural sheet with translucent planes, a strong central wedge and spatter. The diagonal flow works and the layers stay legible. The cloudy, blotchy bottom-right black mass weakens form, tone and surface.”

Form · BUILT

Upper-left trapezoid and central wedge are coherent, walls hold; bottom-right mass dissolves into cloud and the left trapezoid stays slab-like, as in R2.

WEAKEST Bottom-right dark mass, soft-edged and shapeless

STRONGEST Central dark wedge with dry-brush trailing edge

Tonal depth · MODELLED

Left trapezoid and central wedge show graded density and grain; bottom-right black is cloudy and blotchy, not structured tone. Six tonal steps, modulation 0.066.

WEAKEST Bottom-right mass: cloudy, mottled rather than modelled

STRONGEST Upper-left trapezoid graded grey into black base

Layering · LEGIBLE

Pale translucent planes top-right and left stay legible under darker wedges and spatter; two to three passes, sequence not clearly built across the sheet.

WEAKEST Spatter and drybrush laid over greys without order

STRONGEST Translucent grey planes overlapping at right edge

Composition · WORKING

Diagonal movement from upper left to right carries the eye; bottom-centre spike and bottom-right mass anchor it, but lower-left paper is inert and right side busy.

WEAKEST Empty lower-left paper, leftover rather than shaped

STRONGEST Diagonal sweep from left trapezoid through centre wedge

Material and surface · FLAWED

Bottom-right black mass is mottled with cloudy pale blooms visible in colour view; drip spots dot the upper-left trapezoid grey. Dry-brush elsewhere is controlled.

WEAKEST Cloudy blotchy interior of bottom-right dark mass

STRONGEST Dry-brush grain on central wedge's trailing edge

FLAWS

4 distinct places, 1 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, 14 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. A major flaw holds Material and surface at rung 1.

GEOMETRY

Measured from the 16-bit master.

The previous engine (V22) measured this sheet's master file: 1 principal ink mass traced (cyan), 8 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 16 edge segments, 19% crisp, 19% soft or bloomed, 63% broken.

RULE 2A major flaw

Material held at rung 1. Mild waves in the unmounted paper are never a flaw.

THE ARITHMETIC

V23 rating 5.0.

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.
