I'm a convert to gamma correction. Totally. Did the material CG thing on a scene - took me upward of three hours, but it's done. I went from this (rendered using 4 lights, all except IBL at 100% or above):

to this... two lights, Infinite at 60% and IBL at 12%:

Now, I'm going over all my favourite scenes (pz3s) and applying GC to the materials. Good job I have Matmatic and VSS - this would be a nightmare to continue doing it all manually.

I only found out about GC not long ago, but boy-howdy, I'm a devout convert. Got a blog that discusses it:

Not going to pretend I got it all right - feel free to leave comments and corrections - but so far it's been such a dramatic improvement... it's like someone got me a new version of Poser.

Thanks SO much, BagginsBill!
