To use the rule of thirds, imagine four lines, two lying horizontally across the image and two vertical creating nine even squares. Some images will look best with the focal point in the center square, but placing the subject off center will often create a more aesthetically composed photograph. When a photograph is composed using the rule of thirds the eyes will wander the frame. A picture composed by the rule of thirds is more interesting and pleasing to the eye.
Avoid Camera Shake
Camera shake or blur is something that can plague any photographer and here are some ways to avoid it. First, you need to learn how to hold your camera properly; use both hands, one around the body and one around the lens and hold the camera close to your body for support. Also make sure you are using a shutter speed that matches the lens focal length. So if you’re using a 100mm lens, then your shutter speed should be no lower than 1/100th of a second. Use a tripod or monopod whenever possible. In lieu of this, use a tree or a wall to stabilize the camera.
The Sunny 16 Rule
The idea with the Sunny 16 rule is that we can use it to predict how to meter our camera on a sunny outdoor day. So when in that situation, choose an aperture of f/16 and 1/100th of a second shutter speed (provided you are using ISO 100). You should have a sharp image that is neither under or over exposed. This rule is useful if you don’t have a functioning light meter or if your camera doesn’t have an LCD screen to review the image.
Use a Polarizing Filter
If you can only buy one filter for your lens, make it a polarizer. This filter helps reduce reflections from water as well as metal and glass; it improves the colors of the sky and foliage, and it will protect your lens too. There’s no reason why you can’t leave it on for all of your photography. The recommended kind of polarizer is circular because these allow your camera to use TTL (through the lens) metering (i.e. Auto exposure).
