    eliminating scanner noise

    Interesting. This technique was once explained to me as tired and true but I didn't follow the work flow and even with your instructions I got something wrong - I couldn't make the channel mixer layer look like yours, as a smart object. Not sure why. But simply by passing the smart object...

    eliminating scanner noise

    Thanks again, John. Can I ask you to explain the channel mixer approach a bit more basically? If only working on the red channel turns the image b&w how do you get it back to color? Channels have always befuddled me!

    saving w mask

    Hi, I've been cleaning up dust and scratches from a scanned negative, and I have a mask in the layer I'm working on, so I can go back and reveal some of the scratches, if I want. I'm afraid to save the image for fear the mask will no longer be able to access the original image once it's saved...
