Effect

Updraft

Lift and smear detail upward like heat rising through air.

Updraft smears detail upward as if heat were rising through air. Road mirages and chimney shimmer taught the eye that language; the effect stages it as a directional wash.

Gentle values add atmosphere. Strong values turn the frame into rising smoke.
