I've been trying and trying to shoot smoke for ages now after being inspired by Myla's pics. This shot is still too grainy and not as sharp as it should be but it's my best attempt yet and so I'm posting it. I need to get a stronger light to highlight the smoke so I can shoot at lower ISO and higher speed.
'Art Smoke' shots like this are usually shot against a black background and then reversed in photoshop. You want to get as much light on the smoke as you can, but not on the background. You can then add colour in post or sometimes there's colour in the smoke to bring out.
