I've been lurking around Creative Cow for a while now learning new things, but this my first time posting.
Anyway, I'm rather stumped on how to create the kind of effect you might see in a horror movie where the camera, in first person perspective, is focusing on a particular object (e.g. a person) and for a split second, experiences a distortion of vision where semi-transparent after images or ghosts diverge from the object and then disappear or reconverge(often accompanied by a brief but disturbing noise a bit like radio static).Would anyone have any insight into how to create such an effect?
It's probably quite simple, but I'm not entirely sure what to term it, which would explain why I've had so much trouble finding tutorials on this effect.
Sorry if my explanation is a bit hard to understand - I'll try and find an example on Youtube and post it up if I can.
