So what are we supposed to do, run all of our film through noise reduction algorithms so that everything looks like a smeary, digitally perfect mess? You seem to be quite the contrarian about what would be an optional, user-selectable feature that would be more useful than the "psychedelic"...

Considering Vinyl audio disks are now more than 20 years since there production they are historic so we should keep the scratches an a part of the historic remembrance of a by gone era??? This is just to weird for me to consider! While there may be some who actually want this, I am not one of them!...
