Also play around with the angle of the flash head (if it's straight up - and you are taking a picture of something that is a good distance away - then folding down the flash down a notch will change the angle of the light reflecting back (think of it in a billiard mindset :P). A lot of times you can't bounce flash if you are quite a distance away... you need to do direct flash (or at least with the wide fold down flash modifier in flash). I too have the SB-600... and it is adequate to me (but then my old flash that I was using was the SB-28dx - and the 600 is more powerful). A lot of times I find myself dragging the shutter some (setting shutter speed to 1/45 or so [1/30 if I am more desperate]). I use Fuji bodies, but they are based on Nikons thus fairly similar... I remember it took me some time to get used to what I needed to do in order to get good results consistantly... You may just need to keep plugging away and practice... I am not sure where you are located at, but feel free to PM me if you'd like some help over the phone or via live chat or something
