Hello,
Regarding the iSis and XRGA, here's an informative document:
http://www.xrite.com/documents/literature/en/L7-492_i1iSis_RevE_FINAL_en.pdfThis document also says that we should be cautious about comparing measurements from the same iSis made with either i1Profiler (XRGA standard) or Profilemaker (GretagMacbeth calibration).
Interesting times are ahead!
Regards,
Yann
