Photography is "the art or practice of taking and processing photographs". True photography with a camera has so many options to get the final result you want. Here are soem tips:
Compostion: using the rule of thirds makes photos stand above the rest, but you can also use filling the frame, framing, etc.
Manual Focus: To have the most ability to change stuff in a photo, you can use manual focus. Manual focus is often abriviated as an M on the camera dial.
Modes: There are many modes on your camera. Portrait (the little persons face) helps with portraits. Sports mode (a running guy) has a fast shutter and catches moveement. Also, you can hold the button to take a lot of photos. Landscape mode (mountains) has a small aperture and should be used with a tripod. Macro mode (a rose) helps you get closer to a subject and it has a shallow depth of field.
Hope some of these things help. I could go on forever!!!!!!!
