One of the best ways for you to learn about photography is to study examples of how to hold your camera and work your subject during photo shoots. In addition, you can talk to someone who has been in photography for a long time to gain valuable insight on your craft.
Look for patterns in your subject matter, no matter if they happen to be natural or artificial. Patterns add an appealing aspect to a photograph, particularly if they are repeating patterns. You can play off these patterns to get unusual angles or frame your subject relative to the background.
If you are having difficulty holding your camera straight, purchase a tripod. A tripod will go a long way in helping to keep your camera in place, so you can focus on other variables other than balance. Tripods work great if you are in the wilderness or on an uneven terrain.
