Just bought a new Vivitar lightning trigger. We are having a thunderstorm and there have been some killer lightning strikes. The trigger goes off, and the shutter activates. But the camera is missing the lightning bolt. ISO is 100, shutter speed is 30, the lens is set to infinity. In the pictures I can see the light from the street lights etc.... But not the bolt of lightning. Was thinking maybe the flash of lightning is just too fast. Any thoughts or suggestions?
