Not really necessary, IMO. It's long been known that film/video introduces aliasing artifacts like this - the best-known example is probably the wagon wheels in westerns, which appeared to rotate very slowly when filmed. When viewed in real life, of course, no such effect was visible. I'd bet these zoespokes only work on video (or, presumably, film). They are probably also extremely sensitive to the speed at which the wheel was turning; a key feature of a real zoetrope is that the viewing shutter is synchronised with the image frame rate. -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
