oooooops that would explain :) I think you should really make a simple HOWTO with the basic steps everyone needs...or maybe a GUI ? I thought 2.2 gamma and D65 were the default arguments. now I've RTFM and indeed that becomes crystal clear, even though I don't really get the difference between D65 and 6500K but I'll try both...all I want is the lowest dE possible ;) Thanks again for your support and sorry for asking lame questions, -Maxime > Date: Sat, 22 Dec 2007 12:15:16 +1100 > From: graeme@xxxxxxxxxxxxx > To: argyllcms@xxxxxxxxxxxxx > Subject: [argyllcms] Re: dispcal: Warning - RegOpenKeyEx failed with 2 > > lee scratchy wrote: > > > OK so maybe I was a bit too optimistic considering spyder2 support in > > argyll is still in beta stage... > > > > here's a compare of the spyder2pro software on top, and argyll at the > > bottom with the exact same settings on the CRT display : > > http://img231.imageshack.us/my.php?image=comparejo6.gif > > > > there's a major lack of green with argyll... > > It just seems like you've set different white point targets, that's all. > Otherwise the results seem of comparable precision. > > You don't say explicitly what white point you are aiming for.
