Nikon D7000 exposure of smoke?

I'm trying to take a picture of smoke for school. The smoke is from a candle and I'm really tried and can't seem to remember an figure out how to get the shutter speed fast enough to catch the smoke with out it being blurry? Its a new camera that I haven't yet had time to explore. If anyone could help it would be greatly appreciated

What your trying to do is almost impossible without an external flash. With an external flash you must darken the room, set the camera on a tripod set shutter speed to around 2 sec aperture 5.6 - 8, blow out candle and manually fire the flash.

You need an external flash light. Smoke pics work best when lit up from the side against a plain black background that is some distance away.

To increase your shutter speed, use a larger aperture and/or introduce more light and/or increase your ISO.

I would very firmly suggest reading a couple of books on basic photographic principles - it will help you a lot.

You need to use flash to light the smoke.
The built-in flash will work, but you'll get a much better photo if you use an external flash, and put it off to one side of the smoke. You'll need a way to trigger an external flash to do that.

Put your camera in manual mode, pop the flash up, set ISO 200 and about 1/160th sec.shutter speed and around f/8. Take a shot. Adjust the aperture as necessary to get the exposure right.

Actually, at least in my experience, back light against a dark background will work best. I don't know if you can get a high shutter speed to work however because there simply won't be enough light.

Shoot against a dark background. Use a powerful light source at right angles to the smoke (one of those big maglite flashlights focused to a spotlight works pretty well). Aim it through the smoke so you are photographing the light scattered by the smoke particles. Set up like this:

---Dark background---

maglite> > > > > > > smoke… Light background… Camera

be sure the maglite and light background are out of shot. OK to use high ISO as the noise will be hidden by the smoke.
