Sometimes a scene can be cluttered with no sense of subject matter, or it could be a plain scenery making it very difficult to make a good photo composition. You need to pick out something in the picture to centre the attention or what you call the focal point photography.
A focal point in the photography usually uses a small amount of frame within the photo composition. The simplest of the focal point example is an isolated object in a plain scenery. It is best to avoid placing the point of interest right smack in the middle of the picture as it would look rather dull. Best is to place it off centre or perhaps at a corner of the frame.
If possible do pick out any colour contrast which could help to distinguish and make the subject stand out against the composition. For example a red flower against a sea of green grass.
Focal point photography will make the photo composition stand out and would otherwise help to make a static scene become more interesting.
