Scanning Watermarks~further
One trick often overlooked for those with better graphics programs is to examine the scan in the different channels. Scanners use red, green and blue sensors. It's usually possible to remove channel(s) from view and that blocks/removes the colour information of the stamp's ink and enhances the watermark. Going from RGB to CMYK can provide a different 'selection' of 'light'. Would you know of any tricks to reduce "flash" capture when employing a digital camera? We have just purchased a 7 megapixel camera with built in flash, and the results of taking literature always has that "flash" capture in the final image. |

I solved the flash problem by turning off the flash. Many of the digital
cameras work fine with ambient light. Try it. After all, you can immediately review the results. Also, dark pictures are easier to correct with software than white outs. -- Bill Lehr JOBI Philatelic Services specializing in US postal stationery APEX, APS, NSDA, SDI, IFSDA, IPDA, UPSS, PSS 312 Lower Coleville RD Bellefonte, PA 16823-8726 814-355-8871 http://jobi.bizhosting.com "Rod" wrote in message ...

Thanks Bill, thanks Tracy.
marvelous, It's all a bit "fingers and thumbs" with the new camera, and the instruction tome, is rather thick. "JOBI01" wrote in message news:nK0yh.2583$da1.1270@trndny03...
