"There was a mention in another thread about the pros and cons of post gamma correcting some time ago. The final concession about it, by the time a rendered image is exported and Gc'ed in a 3rd party program, image detail would have already been lost. "

True. AFAIK while the newer versions of Vue have render GC, the older ones have post render GC that operates on the image at full depth before it is saved. Kerkythea's post render GC may work the same way. I wonder if saving to .hdr format for editing might work as an alternative. At any rate, the technique may not be as powerful or flexible, but it's certainly easy to use.

I found it interesting that what many consider scripture, Birn's Digital Lighting and Rendering 2nd Ed. only mentions GC in terms of adjusting it in post. Maybe at that time (2006), it wasn't available in most render engines.

When it was introduced in Poser it was, IMO, touted in such an emphatic manner by a few, that one might get the impression that not using GC doomed one to never sitting with the cool kids, and a future of dating outside one's species. Like any other tool, it is not a magic bullet. It may make some things easier, but it can't substitute for learning the other basic techniques.
