My Pentax Optio 330 allows me to do multiple exposures in-camera. The interfaces asks you to
pick an arbitrary base image already in memory, then lets you add a new capture on top of it.
The new capture is digitally combined with the old in one of three overlay modes:
White wins | Average wins | Black wins |
