This picture of the tawny owl I feed outside my kitchen window was taken using it. It has to be dark to achieve this, otherwise you get a ghost effect since the background is also exposed.You also have to get the timing right. The shot above was taken with the flash set set to fire at nine times a second.
But here I had it set to go off more frequently and the owl overlaps. I watched the owl through a telescope as it sat on a post at the edge of the garden and triggered the camera with a wireless remote shutter release. The camera was set on manual with the lens at F4 and a speed of an eighth of a second.
