Why do the photos taken by shifting axis photography feel like miniature models?

It just blurs the upper and lower parts of the picture.

In fact, this problem has little to do with the imaging principle of shifting axis photography, but is a problem of visual experience.

We know that shifting the axis will bring the depth of the scene and weak perspective, but in fact, the depth of the scene has little to do with the sense of miniaturization. The core of this question is "why do weak perspective photos give people a miniature feeling".

Photographic perspective can be simply and rudely understood as "the near is big and the far is small", which is reflected in photos as perspective deformation. The strength of perspective (note: this perspective refers to people's subjective feelings when watching, not the actual perspective relationship. ) is positively related to the volume of the observed object and the viewing distance. That is, the closer the viewing distance, the stronger the perspective; At the same viewing distance, the larger the object, the stronger the perspective. Therefore, when we watch the miniature model, its perspective is often not as strong as the actual scene (the perspective deformation is small).

Although most people don't pay attention to the perspective of objects when watching, our brains will silently record the perspective intensity of objects and miniature models. (the subconscious of the brain, etc.)

Shift-axis photography can correct perspective deformation by adjusting the optical axis. When the physical object appears with the perspective strength of a miniature model, we will mistake it for a set of models.

Finally, give an example of time.

This photo was taken in the 20 1 1 Japan earthquake, and the method of shifting axis photography was not used, but because of the long shooting distance, the sense of perspective was weak, giving people the same feeling as a miniature model.

In the given example, the fourth photo of the square is not as modeled as other photos because it has a relatively strong perspective.

In addition to factors such as perspective, there is another reason:

Uniaxial photos are often brightly colored, even if they all belong to shifted-axis miniature photos, the bright-colored effect is far better than ordinary photos. Because in real life, human eyes, cameras and so on. It is inevitable that the atmospheric environment will affect the imaging of objects (mainly affecting colors, which basically does not exist in small-scale models), and this influence is also an element that constitutes our sense of the scale of the real environment-imagine the city pictures from near to far that you see standing in the window, and then think about those real city model photos. By increasing saturation and contrast, the influence of the atmosphere is reduced as much as possible, and then the sense of realistic scale in our consciousness is blurred.

In fact, I don't know if you understand color painting. This kind of treatment of far and near colors is also one of the compulsory courses. This is also one of the basic technologies for many CG animations and first-person games to simulate the real environment. Why do many paintings or computer games, no matter how delicate they are depicted, make people feel particularly fake, like models, because they ignore the description of the atmospheric environment?

Of course, it's just about color. Facing the specific shift photos, the color processing and effect are different.

This is the work of Norwegian creative design studio Skrekk. The giant coin brought by gle is 20 times as big as the real euro 50-cent coin. If you put it next to any object as a reference, the actual object will look very small and interesting.

If you want the photo to look like a model, you just need to:

1, try to avoid dynamic objects in it. If you can't avoid it, blur them with moving axis photography or something.

2, buildings, streets, ground, try to avoid too many details. For example, garbage and leaves should be swept away.

3. It is best to use bright colors to create the feeling of industrial products.
