Going to get technical for a second

I took this shot today of sweet Grace. She is learning to play the piano. I wanted the shot to focus on the delicate movement of her fingertips. You can tell by the intentional motion blur of her fingertips that she was actually playing me a song at the time. You achieve this by using a shallow f/stop, I think 1.8 here. By using this setting, you only capture a very small portion of the frame in perfect focus allowing the rest of the image to be blurred. This is called depth of field. I love this shot. I hope mom does too.
