[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]I now have new 20.5" shiny-screen iMac. It's a great machine, but my attempts to calibrate it are coming to naught. The glass panel seems to catch light from behind and screw up the calibration, yielding a result in which what I assume should be a neutral grey surround in Lightroom has a distinctly greenish look. My best results come from using the Spyder 3 sensor and software with the dock hidden, the screen fully shrouded, and the room darkened. Color Eyes, which seems more flexible and actually has an iMac profile, yields a even more-green result. My brother, a retired TV engineer, says the problem sounds like it might be due to the software calibrating gamma incorrectly, for at least the green channel. His HP shiny screen monitor calibrates perfectly though, he says, so maybe it's not the screen but some limitation in the iMac's video circuits? In any case, I'm thinking I may have to get a second monitor with a matte screen, maybe an Eizo, but before I did that I'd like to hear other's opinions on this, particularly if you've found a way to calibrate these machines correctly. Many thanks. Regards, Dick
