Ok, so i recently got a job with University Relations at my school. I have to do a shoot tomorrow at a diversity gala event. I'm using a nikon d70s because UR had a 80-200 f/2.8 lens and they wanted me to use their gear for this . They also gave me a speedlight SB-80DX to use with it, but i cant figure out how to make the flash work in some sort of auto mode. It seems like most of the modes dont work (i push the shuttter button and the little flash icon inside the viewfinder just flashes , but the camera wont take a picture) does anyone have a quick answer to this? (or a long answer would work too i suppose) thanks!
