Photography is the art and technology of capturing light with a camera to create an image. It combines creativity and technical skill and connects art and science: it requires both an eye for design and an understanding of how technology works.
Composition is the way elements are arranged in a photograph to guide the viewer’s eye and create a strong, balanced image.

A photograph's exposure determines how light or dark an image will appear when it's been captured by your camera. Believe it or not, this is determined by just three camera settings: Aperture, ISO and Shutter Speed.
The secret to getting a sharp focus on a moving subject is to increase the shutter speed and correct the dark photos by using flash, increasing the aperture or using a high ISO speed. But for a more dramatic shot that captures motion, you could also try panning.
