Digital Photography is the process of taking photographs (pictures) with a digital camera & storing them on digital devices for later reproduction. In simple words we can say that if our camera uses digital technology to create photographs, then it is digital photography.Once a picture is in digital format, we can add a lot of special & unique effects to it with the help of image enhancing software. We can then print the photo out with the help of a printer but if we don’t have a printer then we can send it to a photo developing studio. We can produce digital photographs in a number of ways, such as directly with a digital camera or by scanning a conventional picture or by capturing a frame from a video.
The resolution of digital photographs is not as good as pictures produced from film. This type of photography (digital photography) is best when we need low resolution pictures. These types of pictures (low resolution pictures) are very widely used on the World Wide Web (Internet), because low resolution pictures can be downloaded easily & quickly.
The quality of a digital photograph depends on various factors such as digital camera’s lens quality (resolution, dispersion & distortion), capture format (digital file type: RAW, JPEG, TIFF, film format: 120 film, 135 film, 5x4, 10x8), capture medium (CCD, CMOS, negative film, reversal film etc) & processing (chemical or digital processing of negative and print).
