How to analyze fuzzy portrait

As we all know, the subject of portrait photography is of course people. Yes, in portrait photography, people exist as the main body, and the most important person in portrait photography is to reflect the posture, movements, appearance and even emotions and emotions of people in photos. But in life, people are always in the surrounding environment, and the same is true when shooting. If you don't use the shallow depth of field effect to blur the environmental background, it will easily lead to the disorder of the background, and sometimes the background will usurp the role of the owner. Of course, if you can choose a perfect background, you certainly don't need to blur it. The difficulty of environmental portrait photography is the choice of background. In environmental portrait photography, it is always necessary to ensure the consent of the characters and the environmental background. We call it "the unity of man and nature".

Second, the depth of performance.

Another function of background blur in portrait photography is to express depth and increase the three-dimensional sense of the work. Why is it difficult for us to see the blurred background in landscape photography? Because when shooting the scenery, the three scenes of near, far and far have been able to clearly show the three-dimensional sense and layering of the picture. In portrait photography, there is no division of near, far and far scenes, only the foreground of the characters. At this time, it is necessary to use the background blur effect to give the picture a sense of depth, so as to further realize the three-dimensional sense and layering of the picture.
