Quote - I want well, but if all the renders need to be the same as Poser Pro cause it have GC, where do we go ?

When i use 3ds or rarely bryce or imagine, i dont make a stamp on the GC !!! My work is based only on my light and my shaders ( event is there nothing !) and never on the " how can be view this picture" ... On en finirait plus !!!

Shadering is a good choice, but the better is the friendly bad friend ...

You don't have to GC your renders just because you are using Poser Pro. You can turn the GC off completely if you want to. But the issue here is nothing to do with artistic interpretation, it is purely technical... and it is this:-

The display on a standard sRGB computer screen of a Poser scene rendered in linear colour space, using input image maps that have not been un-gamma-corrected, and an output image that has not been gamma-corrected, is a very specific and avoidable misinterpretation of the physics of light and shade within the scene. This is not an opinion, it is a simple technical fact.

GC in postwork -- even if the user knows how to do it and has the software to do it -- does not correct the misinterpretation that has already been introduced by the linear rendering of non-linear texture maps.

Now, many people who ignore GC completely do produce wonderful works of art that I can only aspire to, so I am not at all critical of anyone's preferred methods. As I said, this is nothing to do with producing good works of art.

But I believe it is far better (especially for those who do not know about these things) to be provided with software that gives them, out of the box, the best possible interpretation of reality, at a particular price point. The purpose of putting GC into Poser is simply to move somewhat closer to that ideal.
