I did send her my version in PSCS using de speckle and curves with some bluring of the uter edges to try and soften the lines left after despeckle. Seems she is happy with that, HOWEVER On Wed, May 25, 2011 at 8:24 PM, Bruce Walker <[email protected]> wrote: > On 11-05-25 4:20 PM, Bruce Walker wrote: >> >> On 11-05-25 11:17 AM, David J Brooks wrote: >>> >>> A good friend of mine has a scan of an old family photo in pretty >>> rough shape and asked me last night if i could help fix it.
