Another step in the process, so it is inherently slower. I agree that for fast shutter timings, the FPS uses a slit... which gives the speed distortion. For slower action, the shutter is fully open. CCD's have several modes of operation including the one you mentioned... take in light, hold light on capacitor, bucket brigade or mux the electricity out. This would give an instantaneous full CCD picture with a slow output to the hard disk or whatever. What I have been able to gather from the elctronics types is that they wish to not use the idea of an instantaneous collection of light, but rather scan the pixels directly in real time with the output rate. I will investigate further, but that is all I have been able togather for now. My guess is that there is some way to make the CCD cheaper.... pure guess, but that's the thought process behind the electronics biz. Thank You Frank Filippone red735i@worldnet.att.net
