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 2026.10.06: 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: 0.059 (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

“This is a single fan of stacked translucent arcs in R3's idiom, with clear ordered layering and fluent bands. But the dark centre is heavy and nearly flat, the composition is one-sided, and the paper has creases. Overall above ordinary, below R3.”

Form · FLUENT

Each arc band follows the curved sweep of a wide brush with clean walls and dry-brush ends at right; the central darkest band reads heavier but still follows the stroke.

WEAKEST Bulky darkest fan band in the centre, heavy filled interior

STRONGEST Upper translucent arc band with dry-brush trailing edge

Tonal depth · MODELLED

Five tonal steps across stacked arcs; upper greys show streaked grain. The central black band shows faint arcs only in stretched view and reads flat at viewing distance.

WEAKEST Darkest central band is near-uniform black in colour view

STRONGEST Upper grey arcs with streaked brush grain

Layering · ORDERED

Several translucent arc passes stack from pale top to dark centre; each overlap stays legible and the order of passes reads clearly across the fan.

WEAKEST Lower-left pale arcs partly buried under dark band

STRONGEST Stepped overlaps of translucent arcs, top to centre

Composition · WORKING

Fan of arcs climbs from bottom centre to upper left with clear radial direction; mass is weighted left and centre, the right paper reads more leftover than shaped.

WEAKEST Right and bottom-right paper left largely inactive

STRONGEST Rising fan rhythm of concentric arcs

Material and surface · SOUND

Ink controlled with no tide lines in dark masses; paper creases visible through the arcs and scattered splashes on right paper are minor.

WEAKEST Crease lines and stray splatter at right edge

STRONGEST Dry-brush grain on upper grey arcs

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, 10 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: 1 principal ink mass traced (cyan), 4 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 15 edge segments, 60% crisp, 40% soft or bloomed, 0% broken.

THE ARITHMETIC

V23 rating 7.0.

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.
