I downloaded a jpg of Arthur Rothstein's "Farmer and Sons in Cimmaron County" from the Farm Security Administration collection of the Library of Congress.
It has always been one of my favorite photos and the scanned print is far from perfect. I spent a couple of hours with the clone tool to remove scratches, dirt and other imperfections. It is a truly beautiful photograph. Although I'm a dedicated film and chemical guy, you've got to hand it hand it to technology in a situation like this.
A huge TIFF file is available which should be capable of yielding an excellent print. The nice thing is that these photos are in the public domain. Rothstein's images cannot be use in advertising etc.
