How to use virtual reality in shooting

When looking at distant objects, nearby objects are illusory. This phenomenon goes unnoticed because people's eyes have the ability to change their focus quickly. Although the camera is not as sensitive as the human eye, it has the same function and can adapt to the physiological needs of the human body when shooting. The camera determines the depth of field by adjusting the aperture, so that the objects in the depth of field are clear and the objects outside the depth of field are blurred, thus obtaining different virtual and real effects. Practice has proved that a photo showing all objects naked will make the picture less vivid and more rigid. The content of the photo will also be obvious and meaningless. It will also form trivial details, mottled colors and little interest, which are equally divided with the main body of family life photos, which is not conducive to highlighting people. Experienced photographers always carefully design and arrange when shooting, reluctantly give up what one favours as a foil outside the characters, and boldly blur. "Easy is hard to empty, easy to take and hard to give up." If family life photography can start from difficulties and use more vague expressions, it will have a new and more beautiful look. The prospect of the most widely used family life photography is vague. The blurred foreground adapts to the physiological function of people's eyes when they look at objects, and provides a natural appreciation process for appreciation: when the viewer's eyes focus on photos, the blurred foreground will not cause line-of-sight interference, and the eyes will naturally fall on the distant "real" characters, forming a clear visual center, and the characters are prominent and pleasing to the eye. Fuzzy foreground makes objects feel close to each other, making it easy for viewers to connect foreground, people and background, forming a contrast among them and strengthening the sense of space depth. The stereoscopic impression of people and scenery will also be vivid and clear. Blurred foreground can also soften colors. The blurring of the foreground makes the colors of some objects in the photo blurred, and soft mixed colors appear, which makes the content of the photo have implicit and hazy meanings. At the same time, it beautifies the form of the photo and adds soft color decoration to the photo. In artistic photography, artistic conception is often created by blurring a large area of objects. Generally speaking, family life photography should not blur too many objects, especially when shooting a beautiful background, and it should not blur the background. Close-range shooting focuses on expressing the mental outlook of the characters, and the blurring of the background makes the formal beauty and connotation of the photos enhanced under the clear and implicit background. Therefore, it is often necessary to use a large aperture to blur the background of family life photos taken at close range. Close-up shooting may also blur some parts of a person's body to highlight some key parts. In most cases, the faces of characters are clear, while their bodies, such as headdresses and hand movements, are blurred. The fuzzy part is not dispensable, it plays a role in showing the content of the photo from the side, suggesting the overall image of the character and strengthening the sense of form of the photo. A photo is both virtual and real, the real thing is more prominent, and the virtual part shows its beauty in contrast with the real thing. People and scenery set each other off in interest, and the colors complement each other, that is, unity and change, that is, contrast and harmony, which makes the contents of photos similar, virtual and real, and turns ordinary into magic, which has a very strong artistic meaning. Family life photos mainly blur objects by using cameras with large aperture, small depth of field and large fuzzy area; The principle of small aperture, large depth of field and small fuzzy area can achieve different effects between reality and reality. The use of long focal length lens has its uniqueness in shaping the blur effect of objects. In addition to the above-mentioned relationship between reality and reality in the form of photos, there are also the relationship between reality and reality in the content, the relationship between reality and reality in the tone, the relationship between reality and reality in the tone, and the relationship between reality and reality in the emotional expression of characters. Virtual and real content means that the image displayed in the photo is real, and the association and imagination generated by the image are empty; The imaginary and real in the tone generally represent the proportional relationship between different areas of the tone; Virtual and real colors generally refer to the relationship between cool colors and warm colors. In the photo, warm colors are imaginary colors and cool colors are solid colors. Cold colors are mainly imaginary, while warm colors are real; The relationship between emptiness and reality in characters' modality means that photo stream's superficial modality is emptiness, while his inner modality is reality.
