Quote - But that means you're not using gamma = 1 on the image then. Which means the incoming gamma anti-correction is turned on (because you enabled GC) but it is not 1. Come on you know very well that if the gamma is not 1, you can't say it is 1.

I'm not referring to the actual Gamma.  I'm referring to the render setting where you type 1 into the Gamma Correction setting.  I understand that if Gamma is applied to the material then typing 1 in the Gamma Correction setting doesn't mean that Gamma is 1.

But someone that isn't familiar with Gamma Correction and gamma applied to materials will easily think that the Gamma is 1, because that's what's typed in the Gamma Correction box. 

For you Gamma is like breathing but for many others from Poser 1 to Poser 7 gamma doesn't come into play on their end, which is why you get such a headache explaining it.  Some users will only see Gamma Correction and never realize that they can actually set the gamma for their materials.
