Re: formula DeltaE2000

Hello Paul! Correct value is deltaE00 2,87 deltaE00 5,74 is wrong. I've faced with the same error in dE2000 function for Octave. The mistake was in formulas for dL', dC' and dh' calculation, there should be simple subtraction (i.e dL'=L2-L1, dC'=C2'-C1'), but wrong function had modulos of the subtractions there, i.e. dL'=ABS(L2-L1) etc.) Hope this helps. Best regards, Alexey Gribunin. > Can somebody tell me that the outcome of deltaE00 2,87 or deltaE00 5,74 is correct with the next values: > - reference L=41,880 a=3,500 b= -33,190 > - measure L=40,488 a=9,092 b= -37,342 > > I try to use the formula in a PHP or javascript environment but I think there is a small error in it? > Maybe someone has the right formula for me. > > Thanks in advance! > > grz.

Hello, Can somebody tell me that the outcome of deltaE00 2,87 or deltaE00 5,74 is correct with the next values: - reference L=41,880 a=3,500 b= -33,190 - measure L=40,488 a=9,092 b= -37,342 I try to use the formula in a PHP or javascript environment but I think there is a small error in it… Maybe someone has the right formula for me. Thanks in advance! grz. Paul Yntema

Calibration recommendations?
by Dimitri Katsaros 21 Aug '24

21 Aug '24

Hey all, So, after quite the age, I’ve gotten myself a new monitor. Going from the now-ancient NEC PA302W to a Dell U4025qw. I know, I know…. no internal LUT, but it met some of my other requirements. Anyway, I know that the spectraview-branded xrite won’t work with it, so I was wondering if anyone has an opinion on what might be my best option. Still Calibrite? If so, which model? Something else? Thanks everyone! Dimitri Katsaros
