Ever wonder how your frail little DSLR can catch something moving at 670 million miles per hour? Exactly what is your camera capturing? The enigma of light has been explained variously as a stream of photons, and as a wave in the fabric of space-time. Is your DIGIC III image processor collecting photons moving at 186,000 miles per second – like some sci-fi flypaper? Or, more poetically, are we photographers “catching a wave” on the ocean we call the universe? And since the light we observe takes time to travel through our viewfinders, are we actually hanging ten on a wave that no longer exists, that has already washed up on the shores of time?
