It’s not difficult to take a good photo, per se. As with many things, taking a good photo is 80% practice and only 20% talent. There are some basic rules that can help you, however, especially in the beginning. But remember, some rules are meant to be broken. So, don’t be too strict and try to experiment.
How to use the rule of thirds? To use the rule of thirds, look at the scene and imagine the grid. The points where the lines cross is where the eye naturally falls when you look at the picture. Therefore, you can use these points as well as the lines as orientation for the most important parts of the pictures. It often looks good to put the interesting object slightly off center.
Example 1: Photographing a landscape
To photograph a landscape, try to align the horizon with the horizontal lines of the grid and you will see that the picture looks harmonious.
Example 2: Taking a portrait
Try to take portraits with the lines going vertically through the eyes.
Example 3: Taking a photo of a building
To take a picture of a house, use the points where the lines cross as pinpoints for the most interesting parts of the building. The vertical lines are helpful, too. For example, try to align the rainwater gutter with one of the vertical lines.
