I`ve been playing with contrast a bit today, rendering at 2.2 gamma and activating a bit of GI. I`m trying to see what the lighting is going to look like if it is all coming from the far end of the room. It`s a poor test as I had to open the window shutters a bit to let enough light in and there is a big gap in the roof! I refined the tracks the shutters move on too. Still real early days. I want to try a combination of this soft atmosperic light and some harsh, local lights to pick up small patches of specularity. Excuse all the artifacts on these images, they are just for testing. 

Oh dear, please ignore this image! I was just testing out the scale of the objects in relation to the splats on the floor. Please belive me this texture isn`t even started yet! Why I had to plug it into the bump channel is anyones guess! Accept my apoligies to your eyes! I was pleased with the contrast i`m getting under the tables though!
