A 2 frame composite image created on one of the bridges over the River Vltava, Prague, Czech Republic. The 2 frames are identical in most respects the camera being mounted on a tripod and the shots taken only 2 to 3 seconds apart. The only meaningful difference between the original 2 frames is that a small group of people walked into the scene from the left during the taking of one image. A shutter speed of 4 seconds rendered them as ghostly blurs.
The girl is rendered, almost, sharp by virtue of her standing still whilst the shutter was open. In the background is Prague Castle which overlooks the city and is illuminated at night.
