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

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: 0.037 (under 0.045 reads as flat).

READ 1, IN ITS OWN WORDS

“This sheet is related to R3: radial translucent layering around an arch opening, with good legible passes. It falls short because the darks are flat inside, the arch is slab-like and the bottom is crowded by near-total coverage.”

Form · BUILT

Radial wedges and arch bands hold their walls and follow the brush's sweep, but the heavy central arch and the lower-left rectangles stay slab-like and filled in.

WEAKEST Bulky dark arch band right of central opening

STRONGEST Radial fan blocks along the upper left arm

Tonal depth · MODELLED

The fan blades step through about five grey plateaus with dry-brush grain, but the dark arch and the lower-centre masses are flat inside (modulation 0.037).

WEAKEST Flat black arch around central opening

STRONGEST Graded translucent greys in the upper fan blades

Layering · ORDERED

Many translucent overlapping blades stay legible at their edges and build depth. The red bands sit as a clear separate pass beside the black.

WEAKEST Dense overlaps in the lower-centre darks lose some order

STRONGEST Stacked translucent blades in the left and right fans

Composition · WORKING

A strong radial arrangement leads to the white arch, and the empty paper at the top is shaped. But 81% coverage makes the lower half jammed and heavy.

WEAKEST Crowded, heavy lower band across the bottom edge

STRONGEST Radial fan converging on the central white opening

Material and surface · SOUND

The ink is controlled and the dry-brush edges are used well. The paper has faint creases, and the pale top-right wedge reads slightly cloudy. Nothing major sits in the principal darks.

WEAKEST Pale cloudy wash in the top-right triangle

STRONGEST Dry-brush edges on the fan blades

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), 6 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 18 edge segments, 72% crisp, 28% 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.
