Hi,
So, I start by creating the patches for the initial Shaper/Matrix profile:
1) targen -v -d3 -f500 -c"Cinema HD.icc" ACD_Shaper
The Cinema HD.icc profile is, I think, the one the OS installs by default
when it recognizes the display, so this should help provide a more efficient
range of patches, right?
Yes.
Next, I create a .cal file. However, I get confused here. If I want to
create a high-quality profile from scratch, am I supposed to use the -k
switch to link to the linear.cal file? If so, where do I find it?
Sorry about that. I'll fix it in the next release. You can easily
make one though, simply run:
synthcal linear
According to the documentation it's supposed to be in the "ref" folder
included with the binary download, but I can find no linear.cal file there.
The only .cal file I can find is the strange.cal file. OTOH, if using the
linear.cal file isn't the best way to perform the next step, what is?
There is a distinction between providing and not providing a calibration
file as a -k argument in dispread. If no calibration curve is provided to -k,
then there will be no vcgt tag in the resulting profile, and the display profile
loader will behave in a system dependent way. If on the other
hand you want the display calibration curves set to linear, providing
-k linear.cal will end up creating a profile that contains a linear
vcgt tag, and a profile loader will set the display calibration curves
to linear.
Hope this helps,
Graeme Gill.
