Alrighty,
I need help...flash help that is

Last night I attempted to do some night shots with my sb-800 and I have absolutely no idea what I am doing with a flash! The look I was going for was really dark contrast pictures, where the flash lights up all the right areas

(also wanted to do a cool silhouette with him and the bike) Didn't happen...
First of all, I found it was really hard to focus correctly at night with it being so dark. (maybe next time I will bring a light as well) ...other than that, I asking for any flash advise if you kind-of understand the look I was going for.
Thanks in advance!
