These are from waaaaaaay back :D Haven't got round till now to share them with you all.
Anyway I was so inspired by fellow Flickerinos smoke shots that I had to give it a go myself, first attempt and still got a long way to go but its a cool start and I wanted to show you all something different :)
Pretty much straight off the camera. Gels on the 580ex 2 were used to colour the smoke.
Setup shot below.
