Scanning and noise
The Canon 8800f scanner has made noises since I brought the scanner home. There is a youtube video on disassembling and cleaning a Canon 8600, which is similar to the 8800. There seemed to be no effect on scanned images, so I put the repair effort off. Noise. There are several types of noise associated with scanners and scanning. Each scan injects some random noise into the image. The noise is different for each scan. The solution is averaging several scans of the same image. More scans is better than fewer. Realistically, the effect after four scans is minimal and three scan work in most cases. There is a free astronomical imaging software program titled StarStax. This programs takes multiple scans of an image and 'stacks' them, mathematically. Corresponding pixels from each image have the values averaged an the result placed in a new image. This removes most of that type of noise. With this in mind, I began the process of scanning the archive film. After a long session of
