I was taking one picutre after another of my dog just hanging out. And I have a few pictures where he is moving and it is blurry, like the one embeded here. I was on a really large apeture, maybe 5.6. But I was using the "A" aperture priority setting on my camera. So I don't know what the camera automatic shutter speed was. Any recommondations how I could have had a better picture come out? I notice that if I go to Manual mode or try and have a high shutter speed and high apeture, the pictures come out too dark... Thanks! FYI, I am using a Nikon D5000.
