Hi, I am new here, also fairly new to photography. I am shooting a Deb ball next month (most of the photographs will be taken inside) and am wondering if I should shoot with the flash? I will be borrowing a 24-70 F2.8 for the occasion but probably won't be borrowing a flash for it, so will just have the onboard one on the Canon 40D. Is there something I can do to make my flash less hard on the photos? I don't really like the look of flash in many photos, but am worried about how much lighting will be in the building where the event is held. Any ideas or help would be very much appreciated.
