Answer 1

You have to use a longer exposure and a flash. Picture would be taken at night time in the dark.

UPDATE: Regarding the question of flash. You can tell a flash is being used because the girls in the photographs are relatively clear and motionless. There are very subtle trails of their figures from being illuminated by the fire. The fire would not be bright enough and/or concentrated enough in one area to illuminate the subjects in the dark. The exposure time was probably closer to 2-3 seconds. PB, I'm glad you liked my answer.

Answer 2

If you look at the lighting on the grass, you can see there is clearly flash involved.

The image was made using a technique sometimes called "painting with light" or "light painting". The girls are likely holding sparklers or something similar while the photographer holds the shutter open for an extended period of time, say a few seconds, as the girls twirl them around the air. Then he fires off a burst of flash at the end of the exposure. This is called rear curtain flash and can be set on most cameras (if there is no such option called this, sometimes a camera's "Night" setting will do the same thing). Actually in this case id doesn't matter much- if the camera was set to fire the flash at the beginning of the exposure, the result would be very similar.

Here is a photo of mine that is similar from last 4th of July of my boys playing with some glow sticks before the fireworks. You can see a similar effect. I don't think I used a tripod, hence the slightly blurred background. The tripod doesn't matter too much unless you are concerned with keeping something in the background sharp.

Answer 3

Take a good look at the Picture. The Face of the 'Performer' is not clear.

It is a Shot with a Tripod. Photo taken with High Speed Film, Longer Exposure, bigger opening of the Shutter etc.. Background will never be in great focus. There is a lot more to learn.

Answer 4

I think the particular photo in question was flashed, there appear to be specular highlights on the girls' faces, and they are relatively clear. I would guess about a 3 second exposure. At twilight, you could probably do it without a flash, though, I have some images using sparklers from last July that are not flashed, but there was some daylight outside.

I am waiting on a wedding to use sparklers...haven't had one yet, just boring old rice and bubbles!

Answer 5

It is called "bulb exposure" or "time exposure". The camera is set to a time exposure where the lens stays open for a while.
This would need to be done on a tripod to eliminate "camera shake" and with a cable release or remote. Sometimes it can be done with a timer.
This captures all the light entering the lens during this time, so it is done at night or in a dark room to prevent overexposing the picture.
Anything that moves will look blurry, so if you want it to be clear it must not move during the exposure.

Answer 6

this is done using a long exposure and don't try this without a tripod because you won't be able to hold your camera steady for so long.
one way of doing this would be to mount your camera onto a tripod set your shutter speed to 3-10 secs(of course this needs to be balanced with your aperture size) then get a friend to get a light source(you can use sparklers or a torch) and wave it around while you take your photos(you can use the light to form words) , of course this is not to be done in broad day light.
the other thing to try is very similar, you break up the ex posture to a number of separate ex postures for example , for an ex posture of 12 secs it may be divided into
4 exposures of 3 secs or 3 exposures of 4 secs, or 6 exposure of 2 secs and you can shift your subject in between exposures.
enjoy yourself and experiment.
you may want to try it with and without flash or any variant there of.
happy shooting.
God bless,

Answer 7

Everything has an explanation. This is just an illusion. They do it by using a longer exposure and a flash. The picture would be taken at night time in the dark, or inside a pitch-black room.

Answer 8

It looks like about a 4 or 5 second exposure and you probably do not need to use flash. I'd guess at about f/8 or thereabouts. Experiment. The prolonged lighting from the whirling lights - whatever they are - is probably enough. To me, the light pattern on the field does not look like a flash was used.

Have the subjects use as little arm motion as possible, trying to twirl the lights with wrist action only. Have them try to hold everything else as still as possible, too.

Answer 9

put the camera on a tripod, set it so the exposure is really long, and have the subject stand in one place while she waves around the glow sticks or whatever.

Answer 10

keep searching the internet.
