Thanks, Abraham, for the explanations and the link.

Although I think I have understood now what gamma is, there is still some confusion about whether we should apply gamma or not.
If Vue keeps the whole workflow linear, wouldnt it be sufficient to apply a gamma correction only on the image maps?  Isnt  the computer monitor doing a gamma adjustment already?

Btw. Have tried to use a gamma higher than 1 on clouds. It seems to me that,  the more I increase the gamma value, the more the clouds are getting washed out?
