Yes, ICC was developed with an output rendered point of view, where the min and
max are limits you want to hit, to make maximum use of the output medium dynamic
range.
Film can have a large enough dynamic range than normal ICC profiles aren't
a complete solution (or rather, you probably want to retain artistic control
over the mapping from the full captured range to the more limited output
medium ranges, rather than baking something fixed into a profile).
Profiles can still be useful in making colorimetric corrections.
rejected it because of relatively poor results. It is better to add synthetic
patches
in a profiler, or manually add them to the target - either by interpolation, or
using
other considerations.
The next release will by default add some extrapolation patches up to the
device min/max values along the neutral axis when -u is used with input
profiles,
to overcome the sometimes unexpected default extrapolation behaviour. You can
always override this with extra patches though, if you don't like what it does.
cheers,
Graeme Gill.
