Photography as a way to capture motion

Video is the default means to capture motion. However, with amateur video equipment, it's hard to add much creativity. Other than zoom in for close up and zoom out to get the overall atmosphere, there is not much that you can play with. You can change the capturing angle as well, but then it's highly limited because stability will be compromised. Of course, we can do video editing afterward, but then it's another story. Video taking tends to be more boring than photography in general.

To take photographs of moving target, it could be real fun! But then the successful rate could be exceedingly low. However, with digital technology, we can do continuous shooting at high frame rate! That significantly increase the chance of taking a good shot.

Large aperture lens (faster focal ratio) helps, for it requires shorter exposure time which increase the chance of success effectively. And at the same time, the background blur which is a result of depth of view is also a very nice effect.

A good and fast focusing motor will also help, so it's always nice to get the lens with faster focusing performance. A camera with fast frame rate is also desirable. Finally, image stabilization is also useful, even when you pan to follow your moving target.

Real life video taking, as compared to professional movie recording, has another big difference - the capture background voice. In that regard, you can hardly have much control over it. People tends to remove the voice channel and put in background music instead. But then for photography, it's not an issue at all. Finally, well captured photograph could become a great reminder of important moments. No media can be better than your memory in terms of the faithfulness, and this kind of photograph can really trigger your lost memory and then the missing frames could be filled up by your real (reminded) memory.
