Digital BW, The Print

I successfully used the 2 percent Gaussian Noise...works like a champ.

It is interesting to see that while the layer still looks dead
black...it adds to histogam...so if one moves the slide...the noise is
added to the black.

Thanks for the perfect solution!!!  This is what I suspected...but I
would not have figured this out on my own.
