This is a pretty simple trick; just set up a camera on a tripod, lock it in place and have the subject move about while you take several exposures, then assemble them into a single image in a photo editing program. Of course, you can branch off from there and really get complex. A group on Flickr is dedicated to shots of “multiplicity” and use the technique to have some fun. Some even employ the technique to explore the many faces we each present to the world or those inner conflicts we all face.
