Ok guys, so let me please ask you this as I NEVER use flash.
I use a light meter so if my ambient is for example, at ISO 64, 250 at f/8, how do I compensate that with my lil' Nikon SB600?

Thank you so much for your quick help.
Tomorrow I'm out at 0400 to document the arrival of a Div. of our brave troops coming home while their families are there to great them, then follow them to the Mess Hall etc... This is one of the ways I give back to not only community but these are the guys/gals that allow me and my boy to do what ever and where ever we choose. My son has this freedom because of the wonderful men and women and I've done these before. (About twice a month) but never this early and never indoors.
Thank you again.
