Yes, provided there�s enough light. That�s really all that counts; most
cameras nowadays use a CCD or CMOS sensor, and they have a shutter speed,
just like your old fashioned photocamera. �xcept its done electronically of
course. With bright scenes, they reduce the time they use to accumulate
light, down to 1/10,000th of a second. This will result in even frozen
explosions:)
A good webcam can do what you want (hint: Philips :-))) ), or a reasonable
camera with grabber card. The 20-30 fps framerate is only used for delivery
of the final image to the card, due to the PAL/NTCS standards.
