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.
Use speed when capturing your pictures. If you take too long, the subject could move, the sun could move behind a cloud or it could start raining. Anything could happen, so don't delay. A camera which allows you to make quick photos will give you the best results.
