One reference, one variable

What the move is

Stop describing the subject and start re-supplying it. Then change exactly one thing per generation so you can tell what caused a drift.

Why it works

A text description is not an identifier: two samples that both satisfy the words can be two different subjects. Identity has to be carried by an image or by the tool's own reference feature.

Step by step

1. Produce one image and accept it as the definition of the subject.
2. Pass that image as a reference into every later generation.
3. Change one variable — pose, or light, or background — never three.
4. Record the seed and settings next to each accepted output.
5. Compare the identity-carrying details, not the overall impression.

Paste this

<attach the accepted reference image>

The attached image is the subject — generate from it, not from a description of it. Change one thing only: <the single variable>. Everything else — <the details that must not move> — matches the reference exactly.

Make it yours

For a product rather than a person, photograph the real object once and treat that photograph as the only description of it that exists.

Variations

• Build a small reference sheet — three angles — and pass whichever is closest.
• Where the tool has a character or identity feature, use it instead of the prompt.
