scanning watermarks

"Pedro" found these unused words: hello all, I'm trying to get a decent digital image of a watermark with my scanner. My method is still not perfect although I manage to see the watermark but not very clear. I'd appreciate very much if anyone could help me or provide directions in achieving this goal in a better way. Thanks, pedro IF your scanner will scan photographic negatives, place the stamp face UP and make the scan. You'll have to severely manipulate the contrast and black/white capture points while scanning, but for many watermarks this will work. Note, it will be 'reversed' so additional work in your graphics editor will be needed. As we always look at watermarks from the back of the stamp I am puzzled as to why some catalogues show watermarks as seen from the front. At least the Italian catalogues show what is seen from the back. -- Tony Clayton |
