arky, what kind of shutter speeds were you needing to get those gunshot shots?
John, sweet miniature images.
Those were taken with a 1D at 1/16,000. Those shots are not possible with the newer CMOS cameras because they rely on the shutter curtains for exposure timing. With the CCD in the 1D, the exposure is timed by turning the chip on and off while the shutter curtain is completely open. That allows for shorter exposures and importantly, for short lived phenomena, a simultaneous capture of the entire frame. The symmetrical muzzle flash can\'t be captured with a moving shutter curtain even if were able to shoot at this speed. I found it interesting that the sensor remains slightly sensitive to light after the electronic exposure, until the shutter closes. This effect can be seen best in the first shot for some reason. If you really want to check it out, the full size shots (caution, noise) can still be found here: http://www.pbase.com/bigflat/1d_45_muzzle_flash
