Time-Stopper photo challenge week of 8/30

The camera is a very powerful tool. It can freeze something that is too fast for our eyes to see. In doing so it can reveal a hidden worlds that we can only see with its help. We need to know how to do it correctly though. The shutter on most cameras can cycle up to at least 1 1000th of a second which is sufficient to freeze most things in place. This also means that the aperture has to be a bit wider to let in more light in a smaller fraction of time. Lighting can be key in these situations. If you look at a high speed photo of a water balloon popping, it can look beautiful if lit correctly. All of the water droplets turn into tiny reflecting crystals. But is the lighting is poor, the image won't "pop". Look for scenes where bright sunlight can shine onto the object that you are shooting at an angle. So earlier or later in the day is a good bet. Flash can help, but the built in flash in most cameras is too harsh and can blow out details in a scene.
Choose shutter priority on your camera and the camera lets you choose the shutter speed and adjusts everything else for you. On some point and shoots this can be accessed in the menus. This is a rudimentary way to slow things down and there are many techniques that use special flashes and low shutter speeds to accomplish this, but for most people, 1 1000th of a second on shutter priority and some good light can make a great photo
