Okay, I am planning on shooting some pic's at a local bar of a band, (just so happens to be my dads band.) I have the equipment you see in my sig. What is your suggestions for flash?? Use it or not?? I am hoping not to blind the musicians, so keep that in mind. Should I get a defuser(sp?) for the flash?? Will it be bright enough? Or should I not use a flash all together?
