Are there any tutorials on how to make realstic looking smoke. Are any plugins?

Try eyecandy from alien skin if you mix eyecandy smoke with photoshops clouds filter you can get some really good looking smoke. Kyle

I usually start with eye candy, then mask the area I want the smoke to be when it is done. I use the smear brush lightly, and a lot of airbrushing to tweak it till it is exactly like i want. I start painting by drawing squiggly little lines flowing in the direction I want the smoke to waft about, then build on that by airbrushing smoke colors, then smear it up a bit. All the smoke in the above pic is done that way.
