Robotic Animal, Digital Image Manipulation

History
Before computers, photo manipulation was achieved by retouching with ink, paint, double-exposure, piecing photos or negatives together in the darkroom, or scratching Polaroids. Airbrushes were also used, whence the term "airbrushing" for manipulation.
The first recorded case of photo manipulation was in the early 1860s, when a photo of Abraham Lincoln was altered using the body from a portrait of John C. Calhoun and the head of Lincoln from a famous seated portrait by Mathew Brady – the same portrait which was the basis for the original Lincoln Five-dollar bill.
The 1980s saw the advent of digital retouching with Quantel computers running Paintbox, and Scitex imaging workstations being used professionally. Silicon Graphics computers running Barco Creator became available in the late 1980s which, alongside other contemporary packages, were effectively replaced in the market by Adobe Photoshop.
