Requirement 3

This photo was taken in green lake park and satisfies requirement 3. In AV mod, I used f/1.4 and set iso of 800 so the shutter speed is 1/8000, which means when she moves, i can get a clear and sharp image. And it was a cloudy day so the light is not very strong. Then i used Lightroom to do the post process by increasing a lot of exposure and a little bit saturation.
