I was palying with the shutter priority mode today and was noticing that the photos all came out black. It's like the ISO is wrong or something. I played with different settings and all but when I set the shutter speed to around 1/400 or higher, the pictures all come out black. What am I doing wrong?
BTW, I was photographing my dog running if that means anything. Also the lens I was using is the 55-200mm VR.
