Shutter Speed

In this photograph I was trying to get blurred hands waving while having the rest of the female in focus. It turned out somewhat grainy and out of focus. The sun was setting, so I had low light and I was really just gambling on what shutter speed to use. This one turned out the best out of all, which I think was set at 1/15 (however it could have been 1/30). This could also of added to the blur/grain since I did not have the camera on a tri-pod. The aperture was at f4.
