I am confused about how Pictograms Incamera profiler works. Until encountering this
plug-in I thought I had a handle on how profiles function.
It was my understanding a
profile described device behaviour without actually correcting
it. I thought by sampling patches for which values were known it was able to
compile a table of control signals and their corresponding colour. From that
table I assumed a much larger architecture was derived by using math to plot a
model, eventually predicting the control signals that would produce the colours
of the chart. Yet, after using Incamera on a digital file of a Colorchecker, it
snapped into perfect form with all the right lab values in all the right places,
as if the right colours had actually replaced the colours the device naturally
produced. This appears to be more
like colour correction than characterization.
How do you make a profile without
a spectrophotometer?
