How the Portrait Engine thinks

1

Multi-reference fusion — the biggest fidelity jump available

One photo forces the model to guess the other side of the face. Two to five photos (different angles, lightings, even ages) let it triangulate the true underlying geometry. Family archives usually have these already.

2

Identity Lock — the single most important line

Every prompt ends with an absolute identity clause: preserve bone structure, eye shape, nose, jaw, skin tone, ethnicity, apparent age, distinguishing marks. Without it, image models drift toward an idealised “AI face.”

3

Life-Stages — unlock age, lock everything else

The Age-Morph clause explicitly allows age to change while forbidding ethnicity, eye colour, nose, ear, jaw, and mark alterations. A child of 8 and an elder of 80 should be visibly the same soul.

4

Style DNA — reference the masters, not the adjective

“Oil painting” is a weak prompt. “Baroque oil in the tradition of Rembrandt van Rijn, rembrandt-triangle chiaroscuro, impasto glazes over ivory ground, linen weave in mid-tones” is a strong one. The model knows the masters by name.

5

Scene Composer — history painting, not portraiture

A portrait says who someone is. A scene says what they did. Setting + Action + Companions turns a bust into a moment from a life: Marie Curie in her laboratory, a mother teaching her daughter, a founder at the podium.

6

Separate the four axes

Medium · Lighting · Background · Composition are always four distinct sections. Mixing them confuses the model. Naming each axis explicitly gives predictable results.

7

Fidelity tier: Flash for drafts, Pro for canon

Iterate on “Flash · Sketch” to find the right lighting and framing. Commit to “Pro · Masterwork” only once the composition is locked.

8

Craquelure, varnish, weave — the finish sells the century

A modern painting looks new. A legacy portrait needs age. We always mention canvas weave, aged varnish patina, and (for Renaissance) fine craquelure.
