I read Danny's reply, so the moonlight shot is off. I know it takes a little fiddling in PS, and I can understand the requirements for this contest. It's not only the total toning, but also there were people carrying torches, and those light areas needn't be less saturated. It can be done in TG, but just too much work. If there were a checkbox/slider somewhere that would reduce overall saturation where light was dull/dark, that would be cool. But there isn't.
Anyway; speaking about requirements for the contest here's my point; I've been fooling you guys
hoping for a discussion. Only a few of you were suspicious.
None of these will be my entry, but having read that assets are allowed, I took it a step further. Too far, in my eyes, and that's my point. If you make, or purchase, or find some nice
photo-based assets it is not very hard to make a render that looks very photographic. In the industry, or with artists stating their points, okay, whatever needs to be used is allright, as long as it conveys what needs to be said. But in a contest it might not be all that fair. Maybe I'm too much of a purist... but I would have stated in the rules that say not more than 10% may be photo-based assets. I also know that e.g. trees are textured by photography, but the trees are still 3D objects.
The earlier renders where also largely photo-based; the mountains, and rock bridge are photographs (on a plane and on a quite simple shape, respectively). Would you consider them renders? Worthy for a contest? I think not.
So to finalize, here's another quite simple render. I quickly made an asset in ZB, used a photo as texture, and put some people and veggies on it.
My real entry will be something that shows what TG is capable of, also in terms of shaping the globe.
