Ernst,
Thank you for the reply.
I have a Spyder 2 that I am using with Argyll and the profiles seem generally good but do suffer from Black Crush. Might not be the fault of the device. Most likely it's the monitor's ability to display shadows. But I recall calibrations done with the Spectrocam being better than those I did with the Spyder on previous OSs.
The Spectrocam disappeared in the US shortly after it's introduction. I think it was a patent issue.
I think that I can use it with Argyll if I measure all the patches manually and feed the data to the application. Before I go to that trouble I will take your advice and search for other calibration software that still supports it.
Thank you again.
Scott
