What is Digital Photography and How it Work?

DIGITAL PHOTOGRAPHY ActualLy, Digital photography is a branch of photography in which use a ray of light sensitive sensors to capture the image focused by the lens, as opposed to an exposure on light sensitive film. After The captured image is stored as a digital file ready for digital processing (colour correction, sizing, cropping, ), viewing or printing.

Until the advent of such technology, photographs were made by exposing light sensitive photographic film and used chemical photographic processing to develop and stabilize the image. By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing.

By contrast, digital photographs can be displayed, printed, stored, manipulated, transmitted, and archived using digital and computer techniques, without chemical processing. And digital images are also created by non-photographic equipment such as computer tomography scanners and radio telescopes. Digital images can also be made by scanning conventional photographic images. Image sensors read the intensity of light, and digital memory devices store the digital image information as RGB color space or as raw data. sensor read the intensity of light and memory.

Main types of sensors: (1)”CCD” charge-coupled device photocharge is shifted to a central charge-to-voltage converter (2)”CMOS” sensors (“Active pixel sensor”). In digital photography The quality of a digital image is a composite of various factors, many of which are similar to those of film cameras. Pixel count (typically listed in megapixels, millions of pixels) is only one of the major factors. the major factor in evaluating a digital camera for most applications.

The processing system inside the camera that turns the raw data into a color balanced and pleasing photograph is usually more critical. Most people take pictures to mark family events, capture vacation images, to share photos of children with family and friends. A large number of professionals take photographs for work and for pleasure. In the digital photography. The ability to instantly see your new photograph is compelling. The ability to electronically share images is also attractive. We are now involved in the photography process .

After we have captured an image, we can change the colours,backgrounds or even the person in the photo and print it ourselves, making further choices such as the number of copies, size of the photo and type of paper. The most amazing thing is that we can do all of this at home and even without a computer. You can scan, print and copy images all without a computer. This technology has allowed us to really enjoy the benefits that digital has brought us. You don’t need to be an expert or spend hours producing a photo.
