PhotographyBLOG links to a few interesting articles on photographic noise and defect reduction tools. Wow, the last link is a very lengthy article comparing different products! Unfortunately, only one application has a chance of running natively in Linux, it’s a Java app. The other apps might work in Wine. YMMV!
Holy Shmoly!
Look what I found today!
Try Noise Ninja or Neat Image or something out in WINE then
I’d love to know if they worked or not.
