Digital Imaging
Thursday, January 27, 2011
Digital imaging is the art of making digital images – photographs, printed texts, or artwork - through the use of a digital camera or image machine, or by scanning them as a document. Each image is compiled of a certain amount of pixels, which are then mapped onto a grid and stored in a sequence by a computer. Every pixel in an image is given a tonal value to determine its hue or color.
In digital imaging, the tonal value of each pixel is represented in binary code. The binary digits for each pixel are called "bits," which are read by the computer to determine the analog display of the image. The number of pixels-per-inch (ppi) is a good indicator of the resolution, which is the ability to distinguish the spatial detail of the digital image.
These are some sample works of my students on Digital Imaging:
