In 1985, Quantel started development of a photographic resolution version of the Paintbox, called the Graphic Paintbox, or GPB. Due to the massively increased computing power required, the machine was huge and incredibly expensive when it was launched in 1986.
Despite the size, the GPB sold well to large photo labs such as Duggal in New York and specialist retouching companies such as Vienna Paint https://viennapaint.com/ in Austria, who published two coffee table books which showed off the GPBs capabilities.
One of the most famous images created on the GPB was Queens Miracle album cover design by Richard Gray
Such was the popularity of the video Paintbox and GPB, before Photoshopped became a verb, the phrase people used to refer to digitally manipulated images was Paintboxed, as in this book from 1994.
