Structure has geometry · Measure it

Where does the weight go?

Drop in a handful of images: one engine's outputs, a series of your paintings, ten photos of anything. The lens finds the structural mass in each and plots where it lands. One centered image is a choice. Twenty centered images about twenty different things are a default.

Drop images here, or choose files. Everything runs on your machine; nothing is uploaded.

Rather play? Where's the weight? pits your eye against the lens on eight pictures. Lighter tests how well you judge value in real paintings.

Δx · Δy · placement

Where the centroid of structural mass sits, from −0.5 to 0.5. Negative Δy is the upper frame.

SDI · dispersion

How far mass spreads from its own centre. Most real images land between about 0.19 and 0.29; lower is gathered, higher is spread.

μ · cohesion

One dominant body (→1) or many equal fragments (→0). Two equal halves read low by design.

xₚ · peripheral pull

The share of edge energy in the outer 15% of the frame. Low means everything is pulled inward.

rᵥ · void

How much of the frame carries almost no structure. Quiet ground versus edge activity everywhere.

Gold = what was measured

The mask keeps mid-strength gradients (85th–97th percentile): texture, marks, modelling. Crisp flat shapes on blank grounds can fool it, so check the gold.
