What differentiates an amateur photographer and a professional is not the mastery of technical details. A good photographer knows how to compose an image well. There are many rules of composition; we will study one of the most commonly used ones. And that composition rule is called the rule of thirds.
The rule of thirds means that you have to place your subject at any one-third of the image frame. Most of the cameras these days have an option to display various types of grids. The grid that is the most common is the 3*3 grid. So, the points where the lines meet is the point where your subjects should be placed. You would have to consider other factors along with it. Placing an image randomly on any of the points will not make an image great. Give it some thought on which point would make the most sense.
