Composition
It is fun to capture a photo of the beauty of world with a camera. No
matter how the world is beautiful, however, a poor composition cannot
capture the beauty of it.
When it comes to composition, it is very important to prioritize subjects.
Composition in photography means arranging objects in a photo. Usually,
abiding by the rule of thirds leads to a good composition.

Rule of Thirds

To use the rule of thirds, divide the image into a 3x3 pattern of equal
rectangles.
To compose photos that best emphasize the subject, make sure the
subject is located at one of the corners of the center rectangle.
