    Noob question. What is a good and cheap way to create a smoke, or fog effect for light flares (i guess the opposite of light flares but air "shadows"? I really dont know the proper term...

    Basically, I have an idea for a side shot with light behind the subject, but I want shadows in the "air" from where the subject is standing

    Am I making any sense?

    Any help would be awesome.

    [edit] Fog shadows

    These appear to be in three dimensions. The thin fog is just dense enough to be illuminated by the light that passes through the gaps in a structure or in a tree. As a result, the path of an object shadow through the "fog" appears darkened. In a sense, these shadow lanes are similar to crepuscular rays, which are caused by cloud shadows, but here, they are caused by the shadows of solid objects.
