One of the most common complaints about digital imaging is the lack of consistency when going from one device to another—most commonly screen to print. Dark prints are the typical complaint, but color shifts are also a contributor to choice language and lack of hair. Yes, we tweak the image until the sky is that perfect hue of blue, or the skin tones have just the right amount of warmth and vibrancy. When it’s all done, the image is posted online or printed and it looks nothing like what we expected. The image is too dark, skin tones are too red, any number of problems. Where did it go wrong?
In almost all cases, the culprit is an uncalibrated display. Back when CRT displays were the common screen type, color could be wildly different and it was usually pretty easy to detect when the display was at fault. With modern LCD displays that isn’t necessarily the case—color is often close to correct in hue, but luminance, or brightness, is where the problem usually lies.
