What I did was to burn an incense stick in my lightbox against a black backdrop.
The incense makes good smoke and blowing it with the camera hurricane blower creates some interesting shapes.
I've seen some really beautiful smoke shots online, and I have a long way to go, but here's my first attempt.
Mother and Child
Is it me or is there an image of the Virgin Mary and Jesus here? Wow! I've seen people bidding on Ebay for a piece of toast that had an image of the Virgin Mary on it. Maybe this is our ticket outta here! If you're interested in this holy work of art...Send me a million bucks, and it's yours...
So how I did this was open up the smoke image in Photoshop;
Duplicate the layer
Invert the layer so the black background is white,
Go to Layers and clean it up a bit,
mess with the color balance and give it some color
Invert it back, so the background is black.
That's about it.
