The rating

THE RATING

T_061, rated 5.5

The combined score, out of 10: V23's reading of the photograph as the read half and V24's twelve tests on the 16-bit file as the measured half, added and divided by 10. The scale is relative to this archive. How each half is made is on the Method page.

How it was measured

FROM THE 16-BIT FILE

What V24 measured.

Plain physical facts with no model involved. Across the year they track how the practice changes. On one sheet they cannot say whether a mark is any good. Millimetres read a few percent high, because the photographs are cropped just inside the paper's edge.

MASS WIDTH102 mm

The width of the ink mask along its medial axis.

DEPTH OF THE DARKS1.40

Optical density at the 75th percentile of the sheet.

LARGEST VOID168 mm

The radius of the largest circle of open paper.

DIRECTIONS0.11

How far the marks align across the sheet. Lower means they run several ways.

BALANCE0.84

Left and right asymmetry of the ink. Lower is more even.

THE FILE3.63

Pixels to the millimetre in the TIFF these were measured from, with the studio light removed.

Read by the Visual Analysis Engine, version 23.13, on 2026.11.04: 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

4 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: 0.057 (under 0.045 reads as flat).

READ 1, IN ITS OWN WORDS

“Layered translucent masses thrust rightward from the left edge with a lively comb stroke and shaped paper, but ordinary overall: the lower mass is cloudy and bulky, overlaps murk at centre-left, and the bottom block sits static.”

Form · BUILT

Upper translucent planes and comb stroke hold as made forms; lower central mass is bulky and loosely bounded; bottom block is slab-like with stiff walls.

WEAKEST Lower central mass, its outline soft and bulky

STRONGEST Comb-ended black stroke at upper centre

Tonal depth · MODELLED

Comb stroke, lower mass and bottom block show grain, banding and stepped density; upper-left dark plane stays comparatively cloudy. Modulation clears the flat limit without being deep.

WEAKEST Large dark plane at upper left, broadly cloudy inside

STRONGEST Banded dry-brush grain in the bottom grey block

Layering · LEGIBLE

Upper planes stack translucently and their edges read clearly; lower down at centre-left the passes merge, so the sequence is not legible across the whole sheet.

WEAKEST Centre-left overlaps merging into murk between the two masses

STRONGEST Translucent planes overlapping at the top of the upper mass

Composition · WORKING

Two masses push from the left edge against shaped pale paper at right, with a column descending to the block; the block sits static and the left is crowded.

WEAKEST Bottom block, static and loosely attached to the masses above

STRONGEST Masses thrusting rightward from left edge into shaped empty paper

Material and surface · FLAWED

Lower central mass has blotchy, cloudy mottling visible in the colour view and confirmed when stretched; bristle edges elsewhere are controlled; faint pale stain on paper lower right.

WEAKEST Cloudy mottled wash inside the lower central mass

STRONGEST Dry-brush bristle edges on comb stroke and bottom block

FLAWS

5 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 5 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. A major flaw holds Material and surface at rung 1.
