Say we are doing a Perceptual intent move, from Adobe RGB to a
printer space.
If the accepted definition of Perceptual is to be believed at all, we
understand that it maps the whole source space to the destination space
- perhaps not as elegantly as we once thought - but that's the Gist -
right?
So, in moving the data to the PCS does it, then, attempt to map the
source space out to the size of the PCS?
In other words, if we coiuld look at the data in the PCS, is it
different data depending on the intent chosen?? Must be - eh?
all the best
