Before anyone bites my head off about the topic, hear me out.
I was attempting to make a scene (keyword attempting), and it seems I was relying on the preview render a little bit to much for atmospheric work. I had what seemed to be a good red decay in the preview, and so I went with what looked good to me. However after my 8 hour render (no water, and seemingly low detail...another topic on its own imho), the atmosphere was extremely red. Just putting out the thought of seeing if this could possibly be fixed later on, or if there is some kind of setting I need to set for a more accurate preview render.
