Why screenshot of same content appears more saturated on iPad 3 retina vs. Macbook Air LCD? When I scale a screenshot of the same image from my iPad 3 retina to that on my MB Air the resulting image appears more saturated (unsure if it's a uniform saturation). Why does this happen? Can I transform my screenshot from my LCD monitor to match a screenshot from my iPad 3 by changing the resolution, saturation, contrast, etc?
You could, but how would you know which is correct?

You would need accurate profiles for both screens. This could be done with colorimeter hardware/software, something like ColorMunki (No affiliation, it's just what I use myself), which can calibrate both your Mac &amp; iPad screens [also PCs, if you have them]

An app like Photoshop [&amp; possibly Gimp, though I've never used it] could then do the translation between the two, though once your screens are correctly calibrated, you may not need to.
