When I start something new, it helps if I understand the components of the thing before I can begin to understand the whole. When I can something down in to is components and understand how they all fit together, my confidence is raised and I can work the thing easier. For instance, looking at a rifle, when you look at it, the machine as a whole appears complex. However when you look at it as an self powered ball bearing, that is housed in a steel tube, the rifle doesn't feel complex. It feels simple and easy. It also make rationalizing its usage and potential that much easier.
The same can be said for a camera. When you press on the shutter, no matter what camera you have, you are exposing the shutter for only a fraction of a second. No matter what camera you have, all of them, are designed this way to stop motion in one frame. This provides a clean, crisp, image that is 'sure' to delight anyone that happens to see it. This is what advertisers and marketing professionals count on, as they use this to sell more camera's. Its also why there is little to no motion blur in many ads. The presence of such would not look appealing for the consumer. When looking at a camera, they would rather look at the images as crisp and clean. They do this as to say if you were to purchase this camera, you too can create beautiful images.
By slowing down the shutter speed of your camera and closing the aperture to something like 'f' twenty-two, you allow not only more light to hit the sensor directly but you allow for more motion to be collected. This will allow you to see trails of color that appear to be smeared on the sensor. In actuality what you are seeing is everywhere that color was present while the sensor was exposed. Doing so will allow you to see colors and light not as things, but as elements that compose on a canvas. This technique is called Slow Shutter Speed Photography. Formally called 'daguerreotype ' images, slow shutter speed Photography was very popular back in 1840. The system allowed for the image to be exposed for about twenty seconds. This allowed for the images to be produced clearly, provided nothing in the frame moved during the exposure. Today, we look for things to move in the frame therefore capturing the 'blur' effect. The following links will show you not only how to use this technique.
