Hello,
I am new to the forum and would like to address some confusion I keep facing every time I read this tutorial. Pretty much at the beginning where the gamma function is being explained it says:
Technical Note: Gamma is defined by Vout = Vingamma , where Vout is the output luminance value and Vin is the input/actual luminance value. This formula causes the blue line above to curve. When gamma<1, the line arches upward, whereas the opposite occurs with gamma>1.
Shouldn’t this be the other way around? Doesn’t the chart show the blue line for gamma = 2.2 hence it should arch upward? Or rather should the formula be Vout = Vin ^ (1/gamma)?
Thanks,
Erik
