Hi Shel, I don't apply noise reduction to all images, I don't find all need it and in some cases it really screws about with the image. Other times it's just great to be rid of. That said there is often an optimum balance between captured detail, noise and sharpening. I stupidly though I'd be able to implement a standard work-flow when I understood all the systems. Now that I do I just have more choices :-( So effectively I try to remove it if I feel it is detrimental to the image but if it's likely that it won't be noticed or become too obvious or pose a problem when other post processing techniques are used then I leave it. Until my little experiment using the Digital Lith process that Mark posted a link to I don't think I've ever purposefully enhanced grain. I do see though how I could use it to disguise various inadequacies maybe to revive the usefulness of a marginal image.
