Digital BW, The Print

Hello Peter,

On L* values you would start with the slider at ( 0 ).  This produces a
linear response( straight line ).  This gives you a standard baseline where
each step is spread out with equal luminance.  But as we know a linear
response, won¹t always print the best pictures.  So to control the overall
density of the profile you would bring up or down the slider just as you are
doing.   

Sometimes when  I¹m printing I¹ll make a view profiles with different
mid-tone settings, then I print the same image using those different
profiles.  I then find the profile that works best for the subject matter.

Joe
