Can you give me a little info on how you did this?
Absolutely... I realized after I did it that I should have taken a picture of the setup. Whoops.
I lit an incense stick and set it in front of a black background (in this case I actually had the incense stick sitting on a dining room chair and had a black T-shirt draped over the back of the chair)
I put my camera on a tripod with my 50mm 1.8 lens and pointed it at the smoke and framed it such that all the camera could see was the smoke and the black of the t-shirt.
I put my SB600 flash with a snoot on it to the left of the smoke and pointed it up and directly at the smoke. I set it up as a remote flash using my D300's commander mode to control it off-camera wirelessly. Note that very little (or none) of the flash was hitting the backdrop (a snoot is a tube over a flash that focuses the light in a fairly narrow beam towards the subject)
I had a remote shutter release cable on the D300.
I then (honestly, though this is kinda lame) stuck my hand where the smoke was and pressed the shutter release down part way to lock the focus. Then I removed my hand, let the smoke settle down a bit, and pushed the shutter the rest of the way to take the picture.
I was doing like F7/8 and 1/60th of a second or something on that order... manual exposure.
Then I brought the image into photoshop, did a bit of a boost on exposure or brightness to make it pop, sharpened it a HAIR, and then adjusted the Hue in the Hue/Saturation slider to add the color.
Thas' it.
