Digital BW, The Print

Dunno, but you would be hard pressed to display that many on a typical
monitor, even a pretty good one.  Unless you are running something like an
Artisan with a good video card, your profile will likely produce banding
that makes different shades appear the same.

Create a new working RGB document in photoshop that is say about 5 times
wider than your monitor, i.e. ~5000 pixels wide if your monitor is 1024
wide.  Paint in a horizontal black-to-white gradient, then select
image-adjustments-posterize and put in 128 for number of shades.  Zoom to
100%.  You should now have 128 bands of gray 5 pixels wide.  You will likely
see that your monitor is not capable of smooth transitions, and it's real
hard to discern the really dark ones.  Bummer.

Now, do the same thing, (leave the first one on screen) but instead of your
working RGB, create the new document in your working gray space.  Look at
the dark end of the gradient, wow that's cool..

But can our eye see anything like this number of steps?  J Vee
