How does the compact Digital Camera

The simplified version of how the camera is that it uses lenses to focus light on the photosensor. Most Compact Digital cameras use charge-coupled device (CCD) as a photosensor. When light strikes the sensor, the electronic image is recorded and transfer it to the organization. After that, convert the image into binary digital data and stored in memory.

In order to obtain an ideal picture, the amount of light reaching the photosensor must be carefully controlled. To achieve this, you need to control the shutter speed and size Opening. And to make things easier, the Compact Digital Camera manufacturers have established an electronic shutter speed and set the size Opening of automation.

Megapixel plays an important role in image quality. It relates to the amount of detail in the image. Therefore, The more megapixels you have the detail you have in your image.

You can see that the cameras today come with optical zoom and Digital Zoom. Optical zoom is most important because it actually zoom in the subject, while the digital zoom just enlarges the image. That's why sometimes you get the picture blurred with digital zoom.

Cameras today also come with LCD screen so you can see the picture they took. Do not misunderstand that the camera compact digital LCD screen is small. It depends on how the manufacturer fir the camera screen.

If you have a camera digital back in the early days, you must remember that the storage device was built into the camera. That gave some frustration because a photographer is necessary to delete the images when the memory is full. Fortunately, as technology evolves, you can now enjoy portable memory storage.

You can now store their images on memory devices such as SD cards or Smart Media Card. When the memory is full, you can tag the memory device, and keep it as your album. Moreover, the device's memory today come in different sizes. The amount of storage memory device depends the quality of your image and how often to take the picture.
