First thing I checked. When I use a normal CGImage + NSView rendering of the image, it looks "right". But OGL doesn't have whatever magic conversion Apple's CGImage/NSImage-based display stuff does automatically. > 2) your screen is not sRGB. and hence PS would be converting to screen > RGB - not sRGB. but I rekon OGL would just display the texture without any > conversion. Yes - OGL is displaying the texture with no additional correction. When not using OGL, images are displayed "correctly". So this isn't directly a lcms issue - lcms is working fine. I was just hoping someone has dealt with this particular issue before. > > Louis Solomon > www.SteelBytes.com > > > ----- Original Message ----- > From: "Paul Miller" <[EMAIL PROTECTED]> > To: "Lcms Liste" <lcms-user@lists.sourceforge.net> > Sent: Saturday, June 07, 2008 7:11 AM > Subject: [Lcms-user] getting OGL preview to match on Apple > > >> I'm loading up a JPEG image with an embedded profile and converting it >> to sRGB using lcms - then I download it to a texture and display it. >> >> The same image in Photoshop, with an sRGB working profile, is much more >> saturated than my version.
