My Macbook screen is not calibrated in windows. Now in Mac OS X i see how dark it is...
But anyway, now you now that i want a Night/Dawn scene. But this turned out really dark o.O Maybe I'll do a night and a day scene...

edit: And i just noticed that i forgot to put a gamma correction on the camera, since I'm working linear. Also I'll probably render the final passes in 32-bit so i have enough room for compositing.
