Photogram
Objects laid directly on photographic paper, so what you see is a shadow, not a picture.
What it does
Man Ray called them rayographs, Moholy-Nagy made them at the Bauhaus, and Anna Atkins was doing it with cyanotype in 1843. There is no lens and no camera: an object rests on the paper and light casts its shadow. Opaque objects render as pure white silhouettes, translucent ones as grey with internal structure visible, and anything not touching the paper throws a soft-edged shadow. There is no perspective at all, because nothing was ever projected.
The prompt
Replace [Subject] with what you are shooting. Everything else is deliberate: the gear, stock and lighting are what push a generator towards this look.
Works well in
Midjourney, FLUX
Pairs with
Cyanotype / BlueprintSolarisation
The Prompt Atlas
Every prompt here is a starting point. The Prompt Atlas is the full system: hundreds of production-ready prompts organised by outcome, with the reasoning behind each one so you can adapt rather than copy.
