My iPad has the same yellowy cast it. Also the color matrix has been changed ( for the worse ). Play this HD test video on a iPad2 and New iPad then look at the green/blue bar on the right side.... is it blue or purple. if you have a iPhone 4 play the same video and see if it matches. http://www.youtube.com/watch?v=yaqe1qesQ8c Also my iPad really puts out the heat.... big difference in others. Let me know what you see on yours |
I calibrate my 27" i7 iMac with the Spyder3 puck using ColorEyes Display Pro. I would prefer to use my i1Display puck but integrated-color hasn't released the update to CEDP which includes support for the i1Display Pro puck.
I calibrate SpyderGallery on my iPad 3 also using the Spyder3 puck.
My iPad 3 appears visibly warmer when compared side by side to my iPad 2--lots warmer. The image on the iPad 2 is far brighter, almost like the whites are bleached. Does this indicate that the iPad 3 is in error, i.e. too warm, or is it the iPad 2 that is too cold? I believe it is the latter. Here's why...
I've displayed the youtube test video on my iPad 2, iMac, and iPad 3.
The video shows virtually the same image colors, including the same shade of purple, when displayed on my color managed iMac as it does on my iPad 3. The colors are virtually the same when viewed with or without calibration in SpyderGallery which indicates to me that the native color profile on my iPad 3 is very good.
Moving on to still images...
Most of my images are from my Canon 7D and are edited in Lightroom using X-Rite Color Checker generated color profiles for my camera. The images I tested were edited in LR4 then exported to a .jpeg file with an embedded sRGB profile which I then loaded onto my iPad(s). In all cases the uncalibrated image colors on my iPad 2 were not a reasonable match to the image colors on my iMac. The exact opposite is true with my iPad 3. The image colors are a virtual match for those on my iMac.
To me this says the colors in the iPad 3 are closer to being proper than those of the iPad 2. If this is true then why have so many complaints been posted concerning the iPad 3 display?
I believe most prefer the iPad 2 colors because the majority of computers have their display set far too cool and far too high in brightness when they leave the factory. The users have become 'trained' to believe that is a 'proper' level. My first iMac came with the brightness set to about 230 cd/m2 and I grew so accustomed the 'bleached whites' which resulted that when I first started using hardware color management I said "This can't be correct. My whites look like they have been dragged through the mud!". I tried repeatedly to make my color calibration come out with what I thought were proper whites and just couldn't do so. When I set my whites to what I thought was proper my prints did not even come close to my display.
After doing a bit of reading about color management I soon came to a different realization concerning white levels. For proper color management a much lower brightness setting than those generally used when a display leaves the factory is required. The required level varys depending upon room lighting conditions, but usually a level between 90-120 cd/m2 is used. I calibrate my monitors to 120 cd/m2 as I edit and view in a fairly bright room.
If I display a blank Safari page on my iPad 2 and compare it to the same blank page on my iMac the iMac whites appear dingy. If I make the same comparison using my iPad 3 the whites are nearly identical.
From this I conclude that with my two iPads at least the iPad 3, though it appears 'dingy' alongside the iPad 2, is much closer to being 'correct' than is my bright iPad 2.
As always YMMV.
