Re: [Digital BW] Digest Number 2903

I sure would welcome a Photoshop plug in version. I am scanning a very large collection of old images from 1900 - 1940 on both glass plates and film, sizes ranging from 120 to 8 x10, condition ranging from wonderful to terrible. Such a plug on would sure cut down the retouching. Bart On Mar 1, 2005, at 7:54 AM, DigitalBlackandWhiteThePrint@yahoogroups.com wrote:
