  heat haze?

  Posted by Phil Summers on September 1, 2008 at 6:12 pm

  Hi Guys – Saw the opening titles to Dragons Den (UK) and was impressed with the heat haze effects – can anyone tell me if its a plug in and any info on said plug would be hugely appreciated.
  Thanks

  hate the show Phil, so haven’t seen the effects for a while, but i would think you could do a pretty convincing effect using Fractal Noise to create a distortion map, which could then be applied using displacement effect.
  Use a gradient map to lessen the intensity of the heat haze the higher from the ground you get.
  Wouldn’t cost you a penny either.

  Some useful tips about this sort of effect near the back of Mark Christiansens AE3 Studio Techniques Book.

  Needlessly pedantic post:
  Real world heat-caused visual effects are caused by refraction between layers of air that are of different densities; the light gets bent. Heat haze is created in After Effects with fairly complex distortion effects and is not merely the application of a simple or compound blur.

  You can get a handle on the physics:

  Nevertheless this appears to be partly a mental phenomenon: beyond a certain background blur level, the brain ignores the background and concentrates on the sharp foreground, yielding a pseudo-three-dimensional effect. One might call it “psychological schlieren imaging.”
  Everyone sees, and routinely ignores, the background distortion effect caused by convection about hot objects in the sun. This is seldom clearer than the case of a hot car roof observed against a suitable background. The thermal boundary layer on the roof, apparently one or two cm thick, is hard to miss.

  This is my standard sigfile so do not take it personally: “For crying out loud, read the freakin’ manual.”

  Image Lounge Mirage effect would do it
