What is the source of the streaks of light in these "miraculous" photos? (link)?

Question

http://www.tldm.org/photos/gallery1.htm

I don't think it is a trick done with leaving camera shutter open or anything, because clearly there are groups of people milling about in the background which would appear as indistinguishable blurs if this was done with say, light-pens and and extended opening of the camera shutter.

BTW, a lot of these were done by polaroid cameras according to the site.

Addition: If the camera was just shakey, causing simple light sources such as candle to leave light traces, then the rest of the imagery in the photo would be blurry, shakey, and indistinguishable. That just seems like simple logic to me.

OK, I guess I'm just going to accept the fact that someone set a tripod and had someone prance about a holy Catholic shrine with a colorful assortment of flashy neon light pens among serious praying pilgrims and respectful visitors to the site. Also managing to leave behind no visible trace of the of the person who would be moving around in the frame with his pen light.

Answer 1

A lot of those look like they were simply in a dark place with one or several specific light sources (the candle, street lights, ect.), taken without any sort of flash and an unsteady hand. I don't think there had to be any sort of extra exposure time or shutter speed, simply because the camera wasn't fast enough as it was to capture the small lights in such a dark place, and the people aren't blurry because they weren't moving as fast as the lights may have been - that's they got the writing, too.

Answer 2

as Lucient says yes it is long exposure, a light pen et cetera,

to get the people not blurry just fire a flash on them while the shutter is open

very easy, use a tripod and cable release, a light pen, a flash

nothing miraculous about it, in fact they are very poor examples

Answer 3

Actually, the shutter was held open for a long time and a light source (pen light, flash light) was used to "paint" the trails of light.

Answer 4

You've recieved some good answers.

A truly "miraculous" photo is one of an empty mall on a Sat. afternoon. It can be done without asking anyone to leave.
