You gave me hope. I needed to try something different so, after I got home from work this afternoon, I pulled the window shades down in my den where the iMac lives, pulled the computer forward so that my desk lamp was well behind the screen, and went through the Apple manual calibration sequence meticulously. After setting the screen brightness at a comfortable level, I adjusted the level and color tone sliders alternately (they interact) until the gray apple disappeared into the striped background of each of the calibration screens completely. I spent about three times as much time on this as I have before. This gave me a nice neutral gray Lightroom surround when I was done. That was encouraging. I then looked at two test files I downloaded from the web, one from DigitalDog, the other from Inkjetart. They both looked fine - neutral grays, solid blacks and pure whites in the monochrome images and natural skin tones and seemingly good color renditions in the color samples with no color casts. Recent images from you and Nathan looked the same, in fact, they looked *very* good. So, I think it's done. My Spyder is going back on the shelf. I had not appreciated how good the internal calibrator is before. You just need to be *very* meticulous when you use it. Thanks for your comments. Now I can back to processing pictures. Yes! :-) Regards, Dick On Apr 05, 2010, at 6:30 PM, Lluis Ripoll Querol wrote: > Hi Richard, > > Nathan and me we have the same iMac shiny monitor as you, mine is 24" > because I don't know why but when I've compared the monitors on the shop > it seems to me that the 24" gave better resolution.
