Thank you for pointing out the error of my ways...

Where in Poser 6 do I gamma correct?!?

I'll hazard a guess its that Material Room!

There is nothing built into Poser 5, 6, or 7 that will do gamma correction (GC) in one click. Only Poser Pro has built-in GC.

For the others you have several approaches.

1) Post work, of course. I find this the least desirable. It requires saving and switching to some other application. Not all image editing tools make it easy to do. It is not a simple matter of light level adjustment - there is specific math that must be performed. You cannot see your results incrementally during rendering, only after you switch to the other application. This means you must guess how to adjust your lights first, and then after rendering find out how you did. For best results, you must stop trying to compensate by over-lighting, so you have to guess how much to decrease your lights in anticipation of the post-work GC.

2. Use my "artistic lens". This can perform GC and other tone-mapping tasks directly as the render is produced. It works via refraction, so it slows your render down a bit, but you get immediate feedback - you will know even partway through the render if you like what you're getting or need to make an adjustment. It works better in Poser 7 than previous because Poser 7 improved the speed and quality of refraction. It produces exact and reproducible results because you're not doing any steps by hand. One problem is that unless you intentionally darken (anti-gamma correct) your incoming material, it can tend to wash out some saturation. However, including an HSV node in the lens can bring some of that back. Certain shaders, such as the default Daz V4 skin shader, have some GC measures in them already. As a result, use of the lens GC can over correct some things. You have to tone down the behavior of such shaders when using the lens. On the other hand, the lens really helps if you have a scene full of simple or naive shaders that make no attempt to compensate for gamma.

3. Make gamma-correcting shaders and use them everywhere. This is the best technique, but requires the most preparation. However, for any given prop or figure, once it is done, it can be saved and used again in the future without any work on your part. It does not slow renders down at all. If done properly, with anti-gamma correction of incoming material (images, colors, etc used in the shader) then it gives the absolute best results. It can match the quality of the Poser Pro built-in GC exactly.

To try the lens, have a look here:

Renderosity forum reply notifications are wonky. If I read a follow-up in a thread, but I don't myself reply, then notifications no longer happen AT ALL on that thread. So if I seem to be ignoring a question, that's why. (Updated September 23, 2019)
