While what you see with your eyes almost always reveals all the detail you wish to capture in your picture, there are occasions when what your camera sees has so much more of the moment.
The milky-blur of a flowing creek; the golden-sway of a field of corn; the rainbow-splash of a Ferris wheel - these are the life-slices made just for your camera's magic-eye.
And Shutter-Speed is how you make an imprint of this sliver of motion.
So, the next time you run into such movement, and you're inspired to coax it into your photograph, simply set your shooting-mode to Tv (Time-Value), bump up your Shutter-Speed, keep clicking, and watch your camera's spectacular take of the subject!
Happy Photographing!!
