RE: curves and gum and Christopher James book


A curve calculated for graphic mode (applied to a positive) will, on the
surface, look exactly the same as a curve applied to a negative -- BUT since
PDN users generally work in binary mode it is this change of mode which
functions to invert the curve.

Can you please explain your differentiation of modes, graphic and bin, as
you have mentioned above?

 When someone figures out how to take a curve and programmatically graft it
onto a custom ICC profile life will becomes much simpler for digital
negative "curvers" because it'll become as simple as selecting a paper in
the print dialogue.

This May, Keith Taylor will be speaking at the f295 symposium in Pittsburgh.
The topic of his presentation will be his method gum printing which includes
his use of color management and the use of ICC profiles.
