shutter speed, ISO, F.stop...if you don't want to have to adjust the ISO put it on auto..just don't plan on getting the best results that you could. same with white balance..and then once you figure things out more you can switch them back to manual and have full control.
chances are you have the shutter speed too high..or the f.stop or both ..try using 320 for shutter and 8 for the f.stop and then adjust from there
