Hiya,
This is smoke photography.

Here's the setup.
Black background behind an incense stick. A strobe light with a snoot sits on the side and positioned so that all the light is focused on the smoke itself and does not hit my lens or the background. The strobe is slaved to my camera

I have to take a number of shots as most do not come out well.

In Photoshop I did a bit of color boosting, but not much else.

Thanks for commenting!
