Some smoke shots in here that I took. Same method as mentioned. black background with a strong light(bowen 500ww monoblock) shing through from the side, but also aiming slightly more towards the camera so i didn't get and spill onto the background. I also used gel filters as an experiment with the colours.
The smoke was created from incense burners. I think I had 2/3 lit to creae alot of smoke. Incense sticks are really cheap aswell and create great smoke, I got a pack of 100's from a chinese supermarket for £2. Good luck
