From Film to Pixels: How It Works

• Digital cameras capture light using an image sensor (CCD or CMOS) instead of film
  • Image sensors consist of a grid of photosites that convert light into electrical signals
• Each photosite corresponds to a pixel in the final digital image
  • The number of photosites determines the camera's megapixel count and resolution
• Color filters (usually red, green, and blue) are placed over the photosites to capture color information
  • The Bayer filter pattern is the most common arrangement
• When the camera's shutter is triggered, the image sensor is exposed to light
  • The electrical signals generated by the photosites are then processed by the camera's image processor
• The image processor applies algorithms to interpret the color and brightness information
  • This process is known as demosaicing or debayering
• The processed image data is then compressed and stored on the camera's memory card as a digital image file (JPEG or RAW)
• Digital image files can be easily transferred to computers, edited using software, and shared online or printed

New Tricks for Photographers
