Both traditional and astro photographers have been using a technique to
remove "hot pixels"(Taking an image with the lens cap on and
subtracting it from subsequent images in Photoshop) from their images.
First off, is this an issue with any film scanners(in broad terms,
specific if you wish)?
I.e. would I benefit from applying said technique to my scans?
Second, what would be the theoretical best material to scan(something
infinitely black that does not transmit or reflect light)if I were to
play with this? I realize there are many scanners/methodologies out
there, so lets think in broad terms both in transmissive and reflective
terms.
Sorry if this is not exactly color related, but I could not think of a
better group to run this by......
