I use a Nikon D40. So with the skies you are saying focus where you want it to focus then move the camera to frame it properly?

With that photo did you have to use a tripod? So basically say you're at 50 mm on your less. 50+ for shutter will make it freeze. 49 and under will make it appear as moving, like blur? Correct? How do you exactly figure out Focal length I don't get it? What is exposure bias? In the photo you posted is the exposure the shutter? For a photo like that does the aperture really matter too much? I know big aperture is best for night, where as during day it doesn't matter.
