Effect

Luma Displace

Displace pixels by luminance for relief and height-map style motion.

Displacement maps push pixels according to another image's brightness, a technique familiar from 3D bump mapping and after-effects style warps. When the map is the image's own luma, bright areas shove detail around like a relief.

Subtle values feel tactile. Strong values turn the frame into liquid metal or heat haze.
