Digital Photography

  • Gerard O’Regan


A digital camera is a camera that produces digital images, and most cameras used today are digital. The digital images may be stored on a computer, printed, or displayed on a screen. Digital cameras have been incorporated into many devices such as mobile phones and tablets. A digital camera captures images as pixel elements, and a megapixel is one million pixels. The resolution of an image is dependent on the number of pixels in the camera, with a higher resolution image requiring more pixels. The quality of a digital photo is influenced by factors such as the optical quality of the lens, the processor and camera sensor, the proper lighting of the subject, the highest resolution on the camera, and the shutter speed.
