Still have not had the chance to compare Munki with EyeOnePro with DTP94 with Spyder3 with EyeOneDisplayII with Spectrocam with Minolta CS-100 with Photo-Research PR-704 but I hope to find a moment to do that soon, for you ;-) / Roger From: argyllcms-bounce@xxxxxxxxxxxxx [mailto:argyllcms-bounce@xxxxxxxxxxxxx] On Behalf Of János, Tóth F. Sent: 1 octobre 2010 06:02 To: argyllcms@xxxxxxxxxxxxx Subject: [argyllcms] Re: ColorMunki measurement drift So, what is the conclusion? It is confirmed that the readings are much more stable after the acclimatization. (It is understandable.) But what about the absolute accuracy? I think I would trust in the very first measurements. If the instrument doesn't work with temperature compensation than it should be accurate at the standard room temperature. Isn't it? So, a "warm-up" can produce much more stable but drifted results. May be we should apply a software based temperature compensation, like the existing one for the colorimeters. (A correction between the standard room temperature and the acclimatized temperature.)
