Spectra View Profiler User Manual 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 52 Spectra View Profiler User Manual CIECAM02 How the effective contrast ratio will be reproduced in an workflow doesn t depends on the monitor alone Also the lightning conditions of the room is having a lot of influence on the effective contrast ratio of the monitor In a very bright en lighted room the effective contrast of the monitor will not be the same like using the same monitor in the same room but without any additional light sources and closed curtains e g dark room One part of CIE Color Apperance Model 02 CIECAM02 is to take care about the luminance of the ambient light of the room The monitors gradation curve can be optimized to the luminance of the rooms ambient light to optimize the effective contrast ratio combination monitor and ambient light by choosing on of the CIECAM02 setting The NEC recommends to u
