Caveat: This post, strictly defined, may not belong in the RT forum but I can find no better location. It was motivated ty a recent addition to RawPedia found here:
If the moderator thinks it belongs elsewhere please feel free to move it.
I have long been interested in creating better camera profiles and was led to the DCamProf software created by Anders Torger. I must confess that, after spending several hours reading the documentation, I was more than a little discouraged by the complexity of this approach. Thus I was overjoyed to find the simple and straightforward instruction (to create a dual illuminant profile) found in the RawPedia article based directly on Anders Torger’s work.
After studying the list of command line entries at step #3 it became apparent that some modification is required for myself and others using a Windows based OS. This post resents my attempt to convert these instruction for Windows users, mostly in the hope that others, more knowledgeable than I, will examine my work and correct any errors.
To simplify the process I have first made the following additions to my OS:
** Append to the PATH environmental variable: a path to the \bin folder found in the Argyll software.
[e.g. D:\MyExe\ArgyllCMS\bin]
**Append to the PATH envronmental variable: a path to the file dcamprof.exe found in the DCamProf software.
[e.g. D:\MyExe\DCamProf]
**Create an environmental variable ARGLREF which supplies a path to the \ref folder in the Argyll software.
[e.g. ARGLREF=D:\MyExe\ArgyllCMS\ref]
With these additions in place the command line instructions now read:
scanin -v -dipn tungsten.tif ARGLREF\ColorCheckerPassport.cht
ARGLREF\ColorCheckerPassport.cie tungsten-diag.tif
scanin -v -dipn daylight.tif ARGLREF\ColorCheckerPassport.cht
ARGLREF\ColorCheckerPassport.cie daylight-diag.tifdcamprof make-profile -i StdA tungsten.ti3 tungsten.json
dcamprof make-profile -i D50 -C daylight.ti3 daylight.json
dcamprof make-dcp -n “RT Camera Name” -n “RT Camera Name” -t acr -o neutral tungsten.json daylight.json “RT Camera Name.dcp”
The command prompt should be opened in the folder containing your tungsten.tif and daylight.tif files. Alternatively prepend the full path to these files to the filenames.
With apologies to the original author (to whom I extend a hearty thank you) I have made some minor changes:
In lines 1 & 2 I have substituted ColorCheckerPassport.cht taken from Argyll\ref in place of ColorChecker.cht from the same source.
In the same lines I have substituted ColorCheckerPassport.cie from Argyll\ref in place of cc24_ref.cie from DCamProf\data-examples.
Any comments or corrections gladly received.
I should also report that I have not yet given the altered program a trial run. Watch this space.
