AuthorSubject: Native Gamma for Artisan   [Go to Bottom of Page]
Sarah E Smith
Posted on Wed Jan 7, 2004 3:04 PM

I've been playing with the settings on my new Artisan, and have some questions about the native gamma of the device. The glossary of Real World Color Management defines gamma (in reference to CRT displays) as: "...the relationship between input voltage and output luminance". The input/output relationship would be expressed as a curve, the midpoint of which is the gamma value. Also in RWCM, it states that the only way to adjust display gamma is in the video LUT, which would mean that the video card controls the input voltage. Am I on track so far? In the posts I have been reading on this site re: Artisan, several recommendations were made to calibrate to the native gamma of the display to get smoother tonality (a technique also recommended in RWCM, per the results of the Gradient Test). Apparently the way to do this is to enter "---" in the gamma field of a custom setting. However, accompanying this recommendation are several warnings not to do so if you aren't sure what you are doing, as it might adversely affect the display in non-ICC apps. My questions are these: 1) Is the only advantage for calibrating to "native gamma" smoother gradients? 2) Is the only danger in calibrating to "native gamma" that non-ICC apps might not display properly? 3) Is there any way to determine what the actual value of the "native gamma" is? 4) When my customers call and ask me what values to use in calibrating their monitors, what gamma should I tell them to use? Since each monitor will have a different native gamma, what would give them the best match to my system? How much does this really matter? I have more questions re: Artisan settings, but I'll take them one at a time...
