Here are some usefull information on digital camera's that should help you out on taking some excellent pictures.

ISO - Is the number in which indicate the camera's sensors are sensitive to light. The lower the ISO number the more light is needed, the higher the ISO number the less light is needed. The higher the ISO is not always desirable as it can have side affects such as Camera noise which causes grain.

Shutter Speed - This is the time that the shutter remains open to allow light to reach the sensor. Shutter speeds are measured in seconds or fractions of seconds. For fast moving objects a high shutter speed will freeze the object, a slightly slower shutter speed will blur the background whilst keeping the image in focus showing the objects speed. The picture below shows a car in focus on a slow shutter speed.


The shutter speed can also be set to "BULB" this will allow the shutter to remain open for aslong as the user holds the shutter release button. This can be used for night time pictures to gather as much light as possible.

Aperture - The aperture controls the amount of light that reaches the camera's sensor. It is much like the pupil in the eye when there is little light the pupil will get larger. Aperture is measured in F-stops, the higher the number the smaller the aperture, the smaller the number the larger the aperture is.

RAW - A RAW image is much like a digital negative. When shooting in RAW and uploading onto a computer you have much more control on editing the exposure and white balance. Unlike Jpeg a RAW image is unprocessed and is not compressed which will mean that they will use up more memory.
