If you would like to practice some of the photoshop techniques I have gone over, but don’t feel like photographing the smoke, I have provided a zip file with a bunch of photos of smoke I have taken
you can find it here
Smoke Photos

If you would just like the smoke in a usable format, I have made a .PSD file with 21 layers of different kinds of smoke, all with built in transparency. just click and drag them where ever you want!
.PSD with smoke layers

Enjoy!

And if you use the smoke in a cool way, be sure to tell me about it!
