I would not ignore any of the things said in here, because they are all correct and ultimately necessary.
As Steve said, and I've written (allthough with doubt where he used certainty) - even the lack of a proper correction profile probably would not explain the difference in brightness (luminance) in your readings, that you are experiencing.
Part of that was also my reasoning to move you over to HCFR - to see if that (with another set of readings) changes anything.
Or go with Steves recommendation of - I would ignore whats said in here and just give up. Dont know what you are doing wrong. But its more substantial.
What patterns are you using. Because according to Steve we are talking big, dumb mistakes now. And he obviously doesnt think that they come from the Colormunki integration in Lightspace..
If or that you can use 200 nits for bright room viewing (with untold impact on percieved color accuracy (do you then use gamma 1.8 for that? (I think also optional according to spec.)
), doesnt help you in any way. Also steve is ignoring, that you are seeing a red tint, while the meter is still underreporting red saturation. (Maybe rightly so - we dont know if this is your eyes not having adopted, or if the image really looks red in your case - in which case, no correction profile would be the most likely cause for that.)
Also - rude.
Also, let me stress this as well, I think its unforgivable to have people learn how to calibrate on Lightspace zro, which is a time limited license to ultimately a very expensive and non standard calibration solution.
Give a man a fish, and then take it away from him and force him to pay 1000 US if he wants to eat again, business model.
Dont support that.
(Lightspace is a great program and calibration solution on the professional level regardless.)
