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.

How the number was made

Read by the Visual Analysis Engine, version 23.8, on 2026.10.16: 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: 0.051 (under 0.045 reads as flat).

FIVE READS

Five reads, agreeing on 4 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

“A spiral of layered radial strokes, close to R3 in idea, with strong ordered translucent passes. The over-dense, near-flat black mass at the lower right crowds the sheet and weighs down its form, tone and composition.”

Form · BUILT

Radial strokes follow the brush's travel around the spiral; the top rays end in stiff rectangular blocks, and the lower-right mass reads as filled bulk rather than strokes.

WEAKEST Lower-right dark mass merges into bulky undifferentiated slab

STRONGEST Arcing strokes winding tightly into the spiral eye

Tonal depth · MODELLED

Modulation 0.051 is only just above flat. Greys step through the rays and the left fan, but the large central-right black barely varies in the colour view.

WEAKEST Dense black lower-right quadrant, near-flat inside

STRONGEST Graded translucent rays at upper right and left fan

Layering · ORDERED

Many translucent arc passes overlap in clear order at the rim and in the left fan, building depth; the order is lost only in the blackest centre-right area.

WEAKEST Overlaps inside the darkest mass become hard to read

STRONGEST Stacked translucent rays around the outer rim

Composition · WORKING

The spiral gives a strong rotating direction, and the left fan answers it. With 80% ink coverage the lower right is jammed and the empty paper is reduced to the left margin.

WEAKEST Crowded heavy mass filling the lower right

STRONGEST Spiral eye drawing movement around the sheet

Material and surface · SOUND

Ink handling is controlled and the dry-brush edges are used well. The stretched view shows paper creases and a small pale cloudy patch at the upper right; neither shows at viewing distance in the colour view.

WEAKEST Crinkled, cloudy texture in the central black

STRONGEST Dry-brush ragged ends on the upper rays

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.

RULE 1Two tonal steps or fewer

Tonal depth held at rung 1.

3 steps: not applied
RULE 2A major flaw

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

none named
RULE 3Any quality below 0.5

The rating cannot exceed 4.

lowest 2.0
RULE 4At least two valid reads

A read that breaks the reply format is discarded.

THE ARITHMETIC

V23 rating 6.2.

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.
