2d scanning and photography

The exact method of 2D scanning or photography to use depends largely on the subject of the image. Sometimes the two methods can be used interchangeably to achieve similar results. The main difference is that 2D scanning involves capturing the image gradually as a line of light moves over its surface, whereas in photography the entire image is captured at once.

‘Scanning’ refers to the process of creating a digital image from a paper document. The term ‘2D scanning’ particularly refers to data captured by means of a two-dimensional scanner (e.g. flatbed scanner, film/slide scanner, drum scanner).

Photography is the process, activity and art of creating still or moving pictures by recording radiation on a sensitive medium, such as a photographic film, or an electronic sensor. If these images are captured using a digital camera, they can then immediately be transferred onto a computer to be edited and either displayed on screen or printed.

In order to digitise photographic negatives or prints, a specialist film scanner can be used. These scanners operate at a higher resolution and have greater colour depth than a standard two-dimensional scanner, therefore producing better quality digital images.
