Prompt

Apply Brûlage as a heat-damaged photographic print, with flowing emulsion distortions, blistered bubbles, rippled contours, and scorched tonal patches. Use silvery blacks, smoky grays, pale translucent voids, and irregular melted edges. Concentrate severe damage around peripheral details while retaining recognizable features. Keep the original subject and composition.

Identify

You see distorted, flowing, and blistered photographic images. The subjects appear to melt, warp, or dissolve into chaotic bubbles and ripples.

Principle

Heat is carefully applied directly to a photographic negative before printing. This physically melts the gelatin emulsion1, shifting the silver particles2 inside.

Example

Raoul Ubac: La Nébuleuse, 1939.

Try it out

Look at a melting ice cube or candle wax and imagine a face stretched across its shifting, bubbling surface.

Background

Brûlage emerged as a surrealist3 technique to disrupt the reliable reality of a photograph. Artists like Raoul Ubac sought to introduce chance and destruction into their creative process. By exposing a glass or film negative to controlled heat, they altered the image physically. The gelatin emulsion layer would soften, bubble, and warp. This shifted the light-sensitive silver particles, destroying the original likeness. When this ruined negative was finally printed onto paper, the resulting photograph showed a haunting, fluid distortion. It merged the original captured scene with the physical marks of heat.

Distinction

Unlike solarization, which uses light to reverse tones during development, brûlage uses physical heat to distort the actual negative.

Aftermath

It reveals that a photograph is a fragile physical object, not just a clear window into reality.

The visual transition from solid stone to molten emulsion exemplifies the destructive beauty of the brûlage process.Illustration generated for the Atlas (AI)
AI illustration: Dissolving still life with blistered textures
05 AI illustration: Dissolving still life with blistered texturesPears and a bowl are shown with large portions of the image field dissolving into bubbly, translucent voids. These circular distortions are the result of the negative's surface reaching a melting point during exposure to a flame.Illustration generated for the Atlas (AI)

Question

Why does the image warp when heated?

Show possible answer +

The image exists inside a thin, jelly-like layer of gelatin. Heating the negative makes this gelatin melt and drag the details.
