Quote from: efflux on November 25, 2012, 03:12:16 AMGood start.This highlights something I'm going to do further tests on in accordance with the whole problem of photography and attempting to compensate for these problems in TG2. I think in a real photo your second image would be massively blown out with light. I'm going to test really pushing for way more atmosphere glow. I don't use any contrast in the render settings in TG2 or try to "fix" exposure which isn't really possible in TG2. I Iet things get badly overexposed (or underexposed) then I post edit it with exr. You can edit exr in Blender which is free. That's a bit convoluted to explain how to do though. It requires nodes in Blender. I may start a thread about this whole topic. Blender actually does do more or less what TG2 can do with exposure but it just gives you options later. Then you export the Blender output to another app (this can be lower bit depth) where you can further tweak diffferent regions of the shot. To me, many TG2 renders look like people are compensating for lighting within their TG2 lighting environment and it doesn't look so photo like because nearly all landscape photos end up being heavily post edited. By doing this you diminish one of TG2s greatest features, it's atmosphere glow. It's the same in movies as well. If you look carefully you can see this editing even in movies i.e ground that has been brightened.
