Good Morning Joel,

Yes sometimes just the flash help the subject out and put a little twinkle in the eyes are light up the shadows little bit. I have a tip for you, go to your fabric store and buy some ripstop nylon make a frame out of PVC
4 x 8 size and attach your fabric to it. It than becomes a much broader light source but still quite soft. sounds like your studio has great light, , portrait student normally shoot?
