SL-80 / World Effects
Heat Shimmer at the Source
Air distortion strictly above the heat source. Nowhere else.
The brief
Refraction ripples bounded to the column of rising hot air above a kiln mouth, asphalt or an engine — with a straight background line for them to bend.
Why it's hard
The moment shimmer appears across the whole image it stops being refraction and becomes a filter applied to a picture.
Name the source, its geometry, and a straight line behind it. Distortion needs something to bend to be legible.

Starter prompt
Built with the CEMI MediaMax system for Google Veo 3.1. Prompts stay in English — that is the language these models take instructions in. Treat it as a starting point and start varying it.
Handheld medium shot, 40mm vintage Cooke Panchro at f/2.8, on a working brick kiln in a village pottery yard at flat overcast midday. A stack of unfired terracotta pots sits in the dirty foreground, rim-chipped and dusted with grey clay slip, thrown soft at the frame's left edge. A potter in a scorched canvas apron swings the kiln's iron door open; the air directly above the door mouth, and for roughly one metre upward, warps into visible refraction ripples that bend the straight mortar line of the far wall behind it. Nowhere else distorts — sky, pots, and the yard's cracked concrete stay optically clean. The operator holds with breathing micro-oscillation and re-frames a few degrees as the heat pushes them back a step. Lit only by overcast daylight and the kiln's orange interior. Roger Deakins' unglamorous industrial daylight. Faint halation on the door's glow.

Shimmer is a refraction gradient, so it only exists in the column of rising hot air — the moment it appears over the whole frame it becomes a filter. Naming the source (kiln mouth), its geometry (one metre up, door-width) and a straight background line gives the model something to bend, which is what makes the distortion legible. The operator stepping back is the physics receipt: the heat is real enough to move a person.
A global heat-haze wobble applied to the entire image — sky and foreground pots rippling too — instead of a bounded column above the kiln door.
