Measured

## How it was read

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](https://peteryuill.art/method).

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.

![T_305]

![T_305, tone-stretched]

![T_305, classed by brightness]

79% of the sheet carries ink

TONAL STEPS

## 2 families of tone.

Every inked pixel's brightness in 64 bins, smoothed; each circled peak holds at least 4% of the ink. Two or fewer: Tonal depth is held at the bottom rung whatever the model reads. A dense sheet of many translucent passes can count low here, so Layering is left to the reads. Life inside the black: 0.050 (under 0.045 reads as flat).

FIVE READS

## Five reads, agreeing on 3 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 quarter-arc study in the manner of R3: legible layered passes and banded arcs, but crowded, blocky in the centre-right, tonally narrow, and with milky patches inside the central grey mass.”

Form · BUILT

Left arcs bend fluently with the brush travel; centre-right passes end in squared, slab-like blocks with stiff, stacked terminations.

WEAKEST Stacked rectangular slab passes, centre-right, blunt and blocky

STRONGEST Large upper arc stroke following the brush's turn

Tonal depth · MODELLED

Arcs carry bristle banding and grain; tonal_steps 2 and modulation 0.0495, just above flat; the mid-grey rectangles read as one even tone.

WEAKEST Centre grey slabs, nearly uniform inside

STRONGEST Banded dry-brush striations through the upper arc

Layering · ORDERED

Several translucent passes: pale under-arc, darker arcs and stepped grey blocks overlapping to the right. The order reads clearly across most of the sheet.

WEAKEST Dense overlaps centre-right become hard to separate

STRONGEST Translucent stepped rectangles overlapping the arcs, centre

Composition · WORKING

The arc sweep gives direction from top-left to the right-hand ends, but ink covers 79% of the sheet; the mass is heavy and the right margin is only partly shaped.

WEAKEST Crowded centre mass; right paper strip leftover

STRONGEST Sweeping arc carrying eye from top to right

Material and surface · FLAWED

Dry-brush edges are well used, but pale milky patches and a curved scrape mark sit inside the central grey mass, visible in colour; crease lines cross the sheet.

WEAKEST Milky cloudy patches inside centre grey slabs

STRONGEST Dry-brush grain at stroke ends, right

FLAWS

## 3 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 3 distinct places, 12 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: 2 principal ink masses traced (cyan), 4 enclosed voids at true size in their grid cells (amber), the main gesture from start to end (red). Of 17 edge segments, 59% crisp, 24% soft or bloomed, 18% broken.

The rating these readings produce, the rules applied and the arithmetic, with Peter's own rating where he gave one, are in [the Archive record](https://peteryuill.art/archive/works/T_305).

## Date

2026.05.14, day 137 of the Crucible Year, one of 9 paintings from that date (6 shown). 28 works were registered in the fourteen days before. Paintings are dated by the day their batch was registered and photographed; each was finished that day or within the few days before. Phase: [P2 The Switch](https://peteryuill.art/phases/P2) (working title).

Made after a calmer fortnight than 15 of the 18 dates before it.
