What role does it play in the prospect of photographic composition? How to blur it to a certain extent? How does photography capture the foreground and a certain blur?

When shooting, properly reflecting the foreground elements can make the picture more full; Making the foreground elements fuzzy to a certain extent can increase the artistic conception and aesthetic feeling of the picture.

How to do this?

First, choose a suitable prospect. The role of the foreground is only to supplement and embellish, and the choice must be moderate, so as not to usurp the role of the master and affect the presentation of the main elements. The general position arrangement makes it on the edge, which can not occupy the middle and "golden point" of the picture, and the determination of the content can not be repeated with the main body, which can play an appropriate role in "filling in the blanks" and "setting off".

Second, use an appropriately large aperture. A suitable large aperture can blur the elements outside the subject, and the foreground is one of the blurred objects. However, the treatment of aperture should be sufficient, and it should not contain unnecessary blurred background because of emphasizing the blurring of foreground, which will cause the consequences of fish in the pool. This requires more research on the word "appropriate", which is difficult to quantify.

Third, keep the foreground close to the camera. This means is the killer of blurring the prospects. As long as it is "close enough", the elements as foreground will be blurred. The essence is to move the foreground elements out of the depth of field through the lens. How close it is depends on the situation, and there is no "quantitative" narrative; However, it can't be too close. If it is too close, it will become chaotic, and it can only be "faintly visible" and "faintly recognizable".

Fourth, use fuzzy tools to adjust moderately in the later stage. This is reserved for future processing. If the above methods are not enough, you can use the "fuzzy aperture" method to further adjust.
