Photoshopped Smoke

Here, what I have done is photoshopped "smoke". With just a black background and a white streak down the middle, I was able to use tools and morph it to look like it does. We found an interesting site on the internet that had all these tips and tricks on how to use photoshop. I don't think that this looks exactly like smoke but if I experimented more with it I think that I could get it just about right.
