Ok can you guys with DSLR cameras give me some advice of what camera settings you have on in these conditions:

-Stationary Car (Daytime)
-Moving Car (Daytime)
-Panning shots (Daytime)
-Stationary car (Nighttime)

Stationary Car: Any really, I usually have mine on AV for Stationary Cars. I would go with f/5.6 or higher.
Moving Car: Depends how fast the car is moving. But I have it on Tv mode and usually I am from 1/100 - 1/400
Panning Shots: Usually around 1/60.

Stationary car: Well, I don't know what you mean by night time but don't even try to shoot in night time without a tripod. If you do want to, i recommend you use the live view to adjust everything to your taste....

This is for a Canon DSLR btw. If you have a Nikon I have no idea what the Tv / Av buttons are called.

Stationary- depends on the lighting but normally i just let auto do that for me.
Moving- between 1/100 and 1/4000.all depends on the time, speed, and lighting.
Pannings- between 1/10 and 1/80 also depending on the speed, angle, and lighting.
Nightime- on a tripod normally between 1/20th of a second and 30 seconds.

Panning on TV mode: 1/25-1/60 usually
Night shots on TV mode: 4 secs - 30 secs
Moving car daytime on A-DEP or P Mode: Auto
Parked car daytime on A-DEP or P Mode: Auto (Ajust exposure if needed)

If you shoot in Jpeg and RAW you'll also be able to fix a lot of things after they've been taken. Not pannings though. Those are really just a hit or miss situation. Often times though i find a slightly dirty panning more appealing than the spot-on perfect ones since they show more of an effect of speed.

Thanks guys!
