Add speed to your image
All commercial cameras have a "Sports" mode for clicking subjects in fast motion. Due to the extremely high shutter speeds used in these modes, you capture the subject in a crisp, clear frame with all the motion in the moment left as a standstill. Though this works great in most situations, instances like the image of the running horse below look a little, well regular.
With a little motion blur, you can breathe new life into images like these. It's really simple, here's how—
Open the image in Photoshop and in the History window (to the left), click on the little square to the left of "Open" as shown in the image above. You will be marking that as the source for your history brush, which you will use in a bit.

Now go to "Filter | Blur | Motion Blur".
