Very interesting indeed. Makes me wonder if one could  minimize some of the
problems as follows:

1) In Photoshop, create a new layer.
2) Add noise to taste (if tasteful)
3) Use displacement mapping based on the greyscale values of the original
image to shift the noise pixels.
4) Flatten and print in BO. (I hate that abbrev too, but I hate typing more)

I'll play with it later. The point is that this would give some
image-related "logic" to the noise dots, perhaps reestablishing what "the
eye tells." Thanks for the idea.
