Quote -  funny thing was when I changed the gamma in and out in your dome back to 2.2 (leaving poser gamma off in render settings) there was absolutely no difference in my render.
love esther

That's because Gamma In and Gamma Out are opposite effects. If they have the same value, you cannot tell them apart, but ONLY if you do nothing in the middle. If you had done something in the middle, such as increase saturation, or decrease brightness, the difference between Gamma In/Out = 1 versus Gamma In/Out = 2.2 would be apparent. This is the whole point of the gamma issue. When you do math on the image, are you doing it in linear color space or not? The only accurate math is in linear color space, so you must bring the image into that space before applying math.

Until you use effects, the actual gamma will not matter as long as they are equal. But I want to teach you to think about gamma - be aware of gamma - make sure your gamma is always right. Then you have more options and get better results when you use those options.
