Re: pictogram's Incamera

Thank you for your detailed answer. This may simply be about loss of innocence.

Are you asking this question because it appears to you that Incamera generated a profile without any need to read sample colors? Perhaps all that happened in your case was that the default profile was applied to your capture by the software, and, serendipitously, it happened to give you correct values for the photo capture you made. It may just be a lucky coincidence.

 

I have been using profiles but never actually made one nor saw one made until now.  I have scanner and camera profiles a technician has made for me using Monaco Proof software, (neither of which come close to the accuracy of the incamera profile when re-examining the target that produced it) The other profiles were made with an IT8 target which admittedly has far more sample points but even the neutrals are never always on the mark. Because of my experience with these other profiles coupled with my understanding (crude at best) of Fraser, Murphy, Bunting I assumed that the sample points of a target were used to deduce primaries from which a virtual model was generated. Therefore the test of a profile would be to turn it back on the target that generated it and measure the variances.

The ease at which Incamera produced perfect results before my eyes forced me to realise that I had overly complicated the procedure. It was simply writing the known lab values beside the control signals for the 24 sample points.  Now that I know that this is all it does I am surprised input-profiling software isn’t free at PC world. 

Thanks for your help.
