So your either using a SB-600 or a 430EX right?
And that guide number of 30m is only for ISO 100, now you have to account for two more stops of light since your at ISO 400. But the 14mm means your now at... wait, there has to be a better way.
http--www.night-ray.com-PhotoCheatSheet.pdf Print a cheat sheet and get back to shooting. Pages 6 and 7 are for the 430 and sb600.
Why are you at 14mm? If it's not because you have a lens that's wider than 24mm then your wasting light. The zoom is supposed to correspond with the angle of view for a lens at the same focal length. i.e. a 35mm lens has the same angle of view that 35mm zoom on your flash puts out, with little light wasted.
