What is the name of the pattern described by spirograph? Or by a pendulum that is both swinging and rotating? A pattern like that, at the maximum speed the sensor can handle for however long the sensor is open (or slightly longer) would probably work. That pattern would likely approximate the gaussian distribution. At lower shutter speeds it would more completely approximate an even blur, or an even gaussian blur. The question being, could it be moved that accurately, that quickly? Whether the idea works or not, I'd wager it's patentable. -- Larry Colen l...@red4est.com sent from i4est -- 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.
