RGB IEC61966-2.1
sRGB is a working space for monitor output only. You find it mainly in the
areas of Internet, multi media video and office applications. The tonal
response curve cannot be described with a gamma function (although
Photoshop, for example, reports a gamma value of 2.2). In the shadows,
it resemble more an L* curve, in the mid tones and highlights it follows
the gamma 2.2 curve. In order to exactly match sRGB data, Spectra-
View Profiler is the only monitor calibration application that offers an
sRGB calibration curve for these applications.
