Webb15 dec. 2015 · The default response curve is a gamma of 2.4, except for Apple OS X systems prior to 10.6 where a gamma of 1.8 is the default. 2.4 is close to that of many monitors, and close to that of the sRGB colorspace. —Another one dispcalGUI documentation: Why has a default gamma of 2.2 been chosen for some presets? Webb22 dec. 2024 · 2. Following the standard notation you should define the scale parameter as $1/\theta$. Of course in this case it makes no difference because $\theta = 1$ but in general when you write the pdf of the gamma distribution the way you did, $\theta$ is called rate paramenter and not scale parameter. This is also made clear in the R …
