Yes, it exists. Yes, it is fun. And yes, it is pleasing to the eye – or at least it can be. This is a photograph I took of some long grass. I used a slow shutter speed of 1/4 of a second at F8 and panned the camera vertically as I shot. Some images were interesting, some were not. You can do this with almost any subject but I find grass, flowers, tress and the like work out good and are easier to do than many other subjects. Give it a try sometime.
