How Digital Imaging Works

Digital imaging has the capabilities of producing surrealistic, out of this world, yet fully believable images. The technology behind a typical photograph and digital image are very different from one another. Photography that is film-based contains, “a number of chemical reactions to produce a print or transparency,”. Whereas, a digital image is associated with, “the capturing of an image, uploading it to a computer, manipulating it, and finally outputting the finished picture,”. The digital imaging process begins with the acquisition of an electronic or photographic image. Regardless of the type of image, after it is captured, it must be converted to digital data. The digital data is then fed into a computer, where a professional quality image is produced. Digital imaging can do anything from, “anchor pictured objects” to “bend, twist, stretch and contort physical objects in cartoonlike ways,”. Once in the hands of a powerful machine, like a computer, digital imaging has endless possibilities. According to Grotta, every pixel can be changed, moved or deleted, and that is the very essence of what digital imaging is all about.
