I thing you may confuse about: what is the focal point?
The focal point is the main of your picture, such as a building, a person, or animal maybe. Besides, the focal point is the main point of interest that the viewer’s eye is drawn to when looking at your picture. You should always strive to consider what the focus of your picture actually is and then planning your photos.
The problems:
They fail to consider what their subject actually is. When you don’t know what you’re taking a picture of, it’s hard to emphasize that element in the final composition.
For example,
In this image, there is no real focal point, and thus there is nothing for the viewer to concentrate on.
After you understand this ideas when you take the picture please think about these questions, “why did the photographer take it?” or “what you want to inform or telling your viewer to know from your picture?”
As a general rule, you only want a single focal point in your photograph. More than one main subject is distracting, and viewers won’t really know where to look. If I show you a photograph in which several objects have equal visual weight, you probably won’t like it, even though you may not be sure why. It is certainly possible to include multiple focal points in an image, but you should do it with care and also to be more practice will gain more experience.
Just easy example of mutiple focal points: This image has the focal point on the front of the flowers
