Coming from someone that doesn't know as much about gamma as you two. Gamma correction is a big time help and it makes things easier for those with limited knowledge. I bet more people are now using better gamma or correct gamma than before there was gamma correction.

I rather have gamma correction and the image gamma script than not to have it because before then, getting the gamma correct was a big headache.  I think those involved with poser understood that not everyone out has the skills or advance level knowledge that you two have.

Poser is a much better program because of Gamma Correction
