if your still active OR anyone else knows...
how do you do this?
im guessing
place camera on tripod on slow shutter speed
walk TO the person and put the light on them (which means you'll stand infront of them blocking them from the camera
therefore that bit leaves me wondering "if it is that then how come the camera doesnt capture the person pasting the light??"
also how does the light trick work?
does this mean it turns to an ultra high / ultra violet frequency wavelength which meens its too high for the human eye to see, meaning cameras capture ultra high / ultra violet light?
answer:
Its the style of the picture, the light source is only from a small LED light.
answer:
probably if you go very fast,with the light and move away when done AND put the camera at longest shutter time, you won't really see you.
