Thanks, if it is all true it is best ascetic tutorial about it :-)
Why it can't be described within documentation this short way ?

Try using another image format (eg. tga) and see if the problem still happens
there. If it doesn't happen, then the problem is simply the wrong PNG gamma
correction value. If it does, then the problem is somewhere else.

But there is another question: what is the fastest way of adjusting designed
enviroment_map to be rerendered with assumed_gamma 1? Adjusting could be started
from calculated factor for color values? How calculate this ?
