Yellow tinge from bottom to top of the screen, 27" iMac

My 27" is showing a yellow tinge when viewing on the bottom of the screen compared to the top?
This makes color corrections on my photos impossible. Anyone else has this problem? You can easily
see it on white or grey background (even in finder windows)

iMac 27" 3.06 GHz Intel Core 2 Duo, Mac OS X (10.6.1)

Bennie,

your pictures look blueish since they've been taken with the white balance of the camera set to "Tungsten" (this is also confirmed by the pic metadata shown here: http://www.flickr.com/photos/48316548@N04/4458580123/meta/)

To obtain an image as close as possible to what human eyes see you should:

. set the white point of the camera to "manual", "custom"or whatever your camera setting calls it by pointing the lens to the white center of the screen. Alternatively, tell your camera to decide by itself by selecting "Auto"

. take the picture(s)

. reset white point to the value you need for ordinary photos



Hope this will help.

Well it's just in the very lower part of the screen and hardly visible. You just don't notice it on an everyday basis. Maybe it will be getting worse over time but then I have 3 years Apple Care to use.

The thing is I've setup everything, copied lots of stuff from the old Mac and I don't feel like doing it all over again. It's really time consuming and boring work.

Talked to the retailer and first thing I should try is to update screen firmware released some days ago. Let's see how things goes.
