I bought aDiana F+ (lomography-)camera,so thatI could makemultiple exposureimages. LaterI realizedthat itpossiblealso withthe Canon350D, using Custom Functions. You need to change "Shutter curtain sync." to position "2nd-curtain sync", and of course you need long exposure time. As you can see, it´s not exactly the same result, but the pictures may be more interesting.
