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.

Peter's own rating

Rating
5
Peter's rating is his own eye, not the engine's, and he never gives a 10.

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

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: 0.046 (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

“Nested curved translucent bands with legible, well-ordered layering. The central dark slab is stiff and only faintly modelled, and the centred, near-full-coverage layout is static. Fine creases cross the dark centre. Overall an ordinary sheet.”

Form · BUILT

The nested curved bands hold their walls and follow a sweep, but the central dark trapezoid and the mid-grey block are bulky and filled in rather than drawn.

WEAKEST Central dark band reads as a stiff filled slab

STRONGEST Lower dry-brush curved bands following the brush's travel

Tonal depth · MODELLED

dark_interior_modulation is 0.046, just above flat. The centre shows faint horizontal banding and the outer greys are grained. The sheet has three tonal steps and no real black.

WEAKEST Central dark mass is nearly flat, with only faint banding

STRONGEST Streaked grey dry-brush bands in the lower third

Layering · ORDERED

At least four nested translucent passes (pale outer, grey, darker grey, dark centre) stay legible where they overlap, and their order reads clearly across the sheet.

WEAKEST Right-edge overlaps blur the order slightly

STRONGEST Concentric translucent passes stepping from pale to dark centre

Composition · WORKING

Ink covers 87% of the sheet. The concentric arrangement holds and the curve gives some movement, but the centred slab is static and the top paper strip is mostly leftover.

WEAKEST Centred block sits statically, leaving little shaped paper

STRONGEST Gentle curve of the stacked bands giving lateral sweep

Material and surface · SOUND

The ink is controlled and the dry-brush grain is used in the lower bands. Fine paper-crease cracks run through the dark centre, and a few small specks sit in the top-left and left greys.

WEAKEST Crease lines crossing the central dark mass

STRONGEST Dry-brush streaking in the lower bands

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, 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: 4 principal ink masses traced (cyan), 5 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 19 edge segments, 21% crisp, 37% soft or bloomed, 42% broken.

THE ARITHMETIC

V23 rating 6.3.

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.
