The photographic images on this website are not computer simulations but scans from photographs of a transparency of the Bianco map projected onto a print of the Vinland Map. The Vinland Map image is the excellent high-resolution Brookhaven National Laboratory picture scaled down for convenience, with ink lines digitally emphasised, most marks & stains removed, and converted to a 2-colour palette- red on white. The image was then printed out on an Epson colour inkjet printer at A3 size. The Bianco Map image is taken from the Veniva Venetian archive resources website; land represented in brown was lightened to white (note that some small islands were missed in this process) then contrast was enhanced and the image was converted to a 2-colour palette- black and white. The image (with an added black surround) was then printed onto a transparency sheet at a size suitable for a 35mm slide mount, using a Hewlett Packard monochrome laser printer. Careful observers will note that my slide cuts off at a point slightly above the bottom of the Veniva image, but neatly coincident with the cut-off point of Africa on the Vinland Map. This is because the opening in commercial 35mm slide mounts is slightly smaller than the true size of a standard 35mm image, so masks a bit around the edges. There is a faint implication here that the Vinland Map maker could also have been working from a 35m slide. The red Vinland Map lines on the photographs of the superimposed maps have been enhanced using Micrografx Picture Publisher to make them more easily visible where they coincide with black areas on the Bianco map. [If my enthusiasm hadn't got the better of me, I would have thought of using the Edge Detection facility in Picture Publisher to avoid having the sea represented as large areas of black. Sorry- but think of it as an incentive to do the experiment for yourself]
