Finished Processing another one of my photos from the Griffith Observatory from last night. This photos does a better job in illustrating the view of Los Angeles from the Observatory that I mentioned in my post:
Unlike the previous photo this one is just a single Raw. It's pretty important to shoot raw if you're shooting at night since you'll want to be able to push your blacks a little and pull down your highlights. This will help you get the nice sharp city lights. You just have to be careful not to push your blacks too much or you'll get the bad colored grainy splotches that are very hard to get rid of.
