I have 2 question about this below that I copied from the scenario page.
Image dependent gamut mapping using device links
When images are stored in large gamut colorspaces (such as. L*a*b*,
ProPhoto, scRGB etc.), then using the colorspace gamut as the source gamut
for gamut mapping is generally a bad idea, as it leads to overly compressed
and dull images. The correct approach is to use a source gamut that
represents the gamut of the images themselves. This can be created using
tiffgamut, and an example workflow is as follows:
tiffgamut -f80 -pj -cmt ProPhoto.icm image.tif
collink -v -qh -G image.gam -ip -cmt -dpp ProPhoto.icm
cctiff Source2Destination.icm image.tif printfile.tif
Q1 I'd like to have a better understanding of how collink does this, is it
explained somewhere? You say above, using a large gamut space cause a lot of
compression, how does doing this with the gamut of the image reduces the
compression and is there a way to visualize this?
Q2 I have mostly version 4 paper profile for now, is there a way to use them
somehow as shown here? A work around maybe?
I have an I1 Display Pro, I wonder if you would have a suggestion for a
spectrophotometer so I can do my own paper profiles, I know this makes 3
Many thanks in advance.
