To avoid this, and to gain an understanding of how integral
focus can be to your shot, practice is a crucial element. For instance, even
with the most professional equipment, manual focus is a critical skill with any
level of video production. Here are a few ideas to experiment with and try out:
Pulling Focus:
Within the frame, attention is drawn towards the subject
with the sharpest focus. This attention can be changed through the use of focus
pulling. For instance, a foreground subject (such as a person) can move away
from the frame, with focus instantly thrown back to the background, containing
a second subject.
Differential
Focus:
By using a deliberately narrow depth of field, emphasis on a
principal subject can be increased. This is down to the contrast between the
sharp focus of the principal subject, and the heavily out of
focus background (and sometimes a foreground subject is used as well which is also out of focus).
Zoom lens and
focus:
Provided the back focus has been correctly adjusted, this is
designed to ensure the focal plane is maintained throughout its range. By
zooming in without manual focus, images can lose focus and become distorted.
By becoming familiar with these ideas, you can be more
artistic and manipulative about what you want the viewer’s attention to be
drawn to. As an important but often overlooked aspect to filming, these
techniques are most often mastered through practice and experimenting.

I’m glad you posted something like this one. Consequently those people get to know about video production techniques. We know that somehow it will help people.
