Digital BW, The Print

Hi Anthony,
 
it's true that the default settings of Photoshop results in auto levels
clipping at both ends, but as I wrote you can configure this tool so as not
to clip at all, keeping in the safe side.
That said, I think (as someone else already stated some time ago in a thread
about Portra400BW), that often black point setting is too conservative, and
that some clipping at the dark end may be good for many photographs
(depending on the workflow, this may make the difference between a print
with good and one with weak blacks). But, obviously, I like to see exactly
what I'm clipping, and that's way I start with the full range of data.

You can set the white and black points visually by using the Curves dialog.
Shift the curve way to the left, then set the black point.  Then shift it
way to the right, and set the white point.  Shifting the curve makes it much
easier to see the darkest and lightest spots in the image, and the curve is
reset each time you set the white or black point.

Another way is to use the Levels dialog.  For each color channel (if working
in color, otherwise not applicable), move the sliders to exclude the flat
area at the top and bottom of the image, if any.  This preserves a little
more detail than the auto-levels operation, which clips the two ends.

I'm not sure whether curves or levels are best.  I use both, mostly on
intuition.
