Thanks for the feedback guys, its been really helpful.

Alan,
Thanks for the tip, I'll brighten up the scene a little more. On my screen I can see the rocks on the right hand side, so I'm guessing its a monitor calibration issue on my side. I'll try to find some info on Calibrating my Screen (which I've never done before).

arran,
I completely desaturated the colour so that's why its lacking in any other colours. When I film the actual footage I won't completely desaturate.

gster123,
Thanks for the link, I'll have a look at it now.

I started going through my DVD library looking at all the movies with night scenes. They all seem to have issues don't they. The big thing I noticed is they were all brighter than mine. I guess with night scenes its the Illusion we are after and not reality.

Looks like I can afford to brighten up the scene more.

Cheers
Paul
