The scan of Three Graves is now done. I use a flatbed scanner with an A4 sheet of glass on it to give me a level surface. Then I scan the painting in sections and use Photoshop to stitch the images together. The lid gets in the way so I can only scan from one edge, thus I'm limited to paintings 60cm in one dimension and about a metre in the other (due to the space I've got on the floor). The whole process takes about a hour for a six section, 50x50cm painting like Three Graves. Thanks to the excellent calibration on the scanner the colours are near perfect and never need adjustment, but the sheet of glass makes the surface slightly blurry and so needs post processing to allow a lifesize reproduction of sufficient quality.
