A digital camera is a camera that captures images, some can also record vidoe clips. It replaced the conventional way of taking pictures on film and then sending them for processing. They are much smaller than the old film cameras. Images can be quickly downloaded onto a computer and using photography software, images can be manipulated to make them look better, a clear advantage over film based cameras. It is also inexpensive because you don’t have to print all your images to see them, you can only print what you like. Printing has also become easier, you can print images straight onto glossy paper and get the same effect as a film camera but you can do it yourself at home. There are also professional digital cameras called DSLR’s which give the photographer more control over the end image. Below is a images taken from a DSLR.


 * **Specifications** || **Definitions** ||
 * Megapixel || This is a measurement of how many pixels(dots) are used to make up an image. It's the image's height in pixels times its width in pixels. For example a picture that is 1600 pixels high and 1200 pixels wide has 1.92 million pixels or 1.92 megapixels. More pixels means a cleaner and better looking image. ||
 * Shutter Speed || This is the time taken for the shutter to open and close so that it can capture an image. This can be changed in Digital SLR cameras to get different effects ||
 * Lens || This is the distance up to which the camera can focus on an object. For example 4.5-45 mm, the higher the end number the further you can zoom and focus on a particular object. ||
 * Aperture || This is the opening in the lens. If the aperture is big, it means more light can get in, which is perfect for low light situations and vice-vers ||
