Photos to do with shutter speed

I took these three photos today using the TV setting on my camera. The TV setting is to do with the shutter speed. This is the amount of time the shutter opens to let light onto your film. Have any of you taken pictures of your children when they have been jumping around, and they have all turned out blurry, even on the sports setting. If you adjust the shutter speed you can solve this problem. A fast shutter speed decreases the amount of light getting in, which enables you to take a picture of something moving fast. The three pictures above were taken at 1/500. On the other hand, if you want to take a picture of say a waterfall, and get the water kind of moving, to create a mist, then you would need a slow shutter speed say at 2 seconds. Once again, the aperture (focus side of things) would automatically set itself in this setting. But you would also need a tripod for this kind of photo. I haven't tried this yet, but can't wait to do so. There are so many things I want to learn, but you have to start somewhere. Getting the right shot for your layouts, makes all the difference.
