Another exception is, if the CMYK image has been sharpened. The contrast on the sharp edges will be accentuated by increasing the dark pixels and reducing the light ones. When you now convert using BPC on, CMM now takes those few pixels that are over 91% Black and tones them down to your max of 91%. As a result, it also lightens all the rest of the image accordingly. So your shadows will appear light (with a max black printing in the low 80's).

Martin,
I can only speak for myself.
The general recommendation is to leave BCP on for most all types of printing
from Photoshop and I would say definitely for photographic prints with
either perceptual or RC.
Color Proofing (say like in pre-press) is more of the exception and is where
some people don9t use it (BPC) for a variety of reasons. One reason is that
some claim that there prints have too much detail (and therefore cant match
the press) and another is that most rips don9t support BPC.
