Hey all!

I am going to be photographing an Family's Engagement party in the new year. I have an SB-700 flash with Nikon D7000 and my two lenses 50mm F/1.4 and 18-200 3.5-6.5.

I was wondering what should i be using to photograph the night. Not to sure where it is going to be at most likely a hall or something of some sort.

What Lens and setting for the Flash and camera.

Any help would be greatly appreciated

Thanks
