Here is another picture scanned from a magazine ad (first is scan, second is processed image).  Unfortunately, I did not optimize my scanner settings for a picture with so much black area, so the result was grayish.  Since the original was not present, I had to correct the gray cast in the image.  Then I removed the logo and text, and even patched over a bare spot of skin to make the expanse of fabric in the picture unbroken (it seemed more "luxurious" that way).  Doing this without altering the fabric wrinkles or texture was my challenge and my motivation here.
