Waterfall

What you're seeing here, is a shot from actual ingame footage (with disabled UI).
I used GIMP to add contrast, saturation, some extra color correction, as well as some Depth of Field.

DoF was a pain in the ass to make since I didn't know how to edit images that way, but it was fun learning the way by myself
And btw I'm using NebuLa's LITE HD Textures, and W.A.T.E.R. mods!
