In camera shooting, in addition to the most common trisection, there is also a very unusual auxiliary line - the golden spiral. Although the golden spiral is unpopular, it is much more advanced than the trisection line. Many photography experts also like to use the golden spiral, and the composition of the golden spiral is more in line with the aesthetic concept of human subconsciousness. Let's gradually understand the role of the golden spiral.

The golden spiral can be said to be an auxiliary line that fully conforms to the golden ratio. When we look at each side length, the side length ratio of each adjacent square is 1:1.618, which is often called the golden ratio. In this way, the equilateral arcs of several squares that are constantly divided are connected to form a golden spiral.

In photography, using the golden spiral, we generally prefer to place the main subject in the center of the spiral. For example:

This is the screenshot of Nubia Z5. At present, only Nubia Z5 has a golden spiral auxiliary line in the native camera. Of course, some other third-party photography applications also have such auxiliary lines. For example, if Xiao Bian wants to shoot the signboard, he will choose to align the center of the spiral with the signboard for composition.

This is the effect of shooting. If the road sign is placed in the middle of the picture, the picture becomes lifeless. Now put the road sign on the right side of the picture, and leave the left side for the road, cars and pedestrians to fill in, and the passer-by and the icon of the road sign just echo, the whole picture will be vivid.

Especially when shooting at macro, it will be more useful because the main body can be highlighted by the virtualization of the background. Xiao Bian took one of the flowers as the main body when shooting the flowers, and there were one or two flowers in the space on the left as the background.

As above, the head of Iron Man is taken as the main subject, and the empty space on the left is filled with its background.

Then Xiao Bian found an illustrative example of such a golden spiral on the Internet for everyone to see, without too much entanglement.

(The picture is from the network) The picture is a little small, but it should still be clearly visible. This picture points out that in some film and television works, there will also be cases of composition based on this golden spiral. Of course, the film lens is often moving, and the example of the picture is only a screenshot that meets this ratio, so there is no need to study too much.
