Ok first of all I have a Nikon D70. I am thinking of getting an off camera flash. I am going to do some bridal shots outside on campus for my sister in June. Her wedding photog offered to let me use her reflector, gold on one side/silver on the other. I was wondering if I would need the off camera flash for fill lighting maybe? Anyways. I dont really know anything about them so I was wondering what is the best kind to get and how much do they cost? Also, do they run off the camera battery? And where can I find one of those dome things you put on to diffuse the light and how much do they cost? Also, will I need a light meter? Sorry for all the questions!! Thanks!!
