I'm new to the forum and I'm wondering if you could put forward some solutions for a little problem I've encountered?
I'm currently working on a photographic project. This involves a ballerina moving through the frame of the camera over a long exposure. To convey the sense of movement we want to have the ballerina holding some sort of light sources in her hands and then these will leave a light trails on the exposure. The light sources must be as small as possible, so as to be easily concealed but they need to be very bright.
Think writing in the dark with sparklers for reference! This will all be shot against a black background with a final flash shot at the end of the long exposure to show the model/ballerina frozen in movement (this is why the light sources must be small, so they don't show up much in the flash)
Any suggestions will be greatly appreciated! Great forum guys, cheers!
