A digital camera is the photographic device that stores images in a digital format rather than storing them on any roll or a film. This is done by converting the light energy into electrical energy. The device that converts the light energy into electrical energy are called CCD or charged coupled device. These CCDs are made up of silicon  which converts light into electrons. When the light is converted in to the electrical signals, they are sent to the ADC (Analog Digital Converter). ADC, in turn, converts electrical signals into the digital signals.

Each digital camera has some key factors responsible for the quality of the image and the overall performance of the camera. It is advisable that you carefully consider all the major aspects and features of a digital camera. Some of the basic factors are pixels, LCD, battery, zoom lens and exposure control.

The first important feature of a digital camera is the resolution or a number of pixels it supports. The pixels are measured in millions and one million pixels are called a mega pixel. You will find cameras with several mega pixels in the market. A standard quality camera should be at least 3 mega pixels camera. The semi-professional digital cameras have  around 4 to 6 mega pixels. And the advanced professional photographers use a camera of more than 6 mega pixels. More the number of pixels, the bigger and finer  image you will get from the camera.

Memory is one of the most important things which affect the functioning of a digital camera. The higher memory of your camera ensures the higher number of images being taken and stored in the digital camera. The memory of a camera is measured in mega bytes. You can enhance the memory of a digital camera by using memory cards and memory sticks. They are an essential accessory for outdoor shooting plans.

Professional photographers should pay attention to the exposure control and zoom lens functions. Exposure control functions like light shutter speed and lens opening is critical for professional photography. The light shutter speed must be fast enough to capture a  fast moving object or a  moving background.

You also need optical zoom and digital control functions for the perfect focus of the subject. The optical zoom moves the lens physically in and out to view a subject closer and at a distance. Many people think that digital zoom means the better quality pictures, but the fact is that the digital zoom results in poor quality of images. So when you look out for a digital camera, consider its optical zoom.

The best thing about a digital camera is that you can transfer the images to your personal computer. You can add several audio and visual affects to the photographs as well. The images can be made to look really professional by applying hundreds of professional photography styles to them. Sharing the photographs via the net is also very convenient by using the digital camera software.

So keeping all these factors in your mind, you would buy a camera which meets all your requirements and needs.
