What should I pay attention to when shooting?

1, what is a good photo ① A good theme: A good photo needs a good theme, and whether the theme is meaningful depends on the service object of the photo, which is called consumption positioning. Themed photos should be able to tell a story, convey an emotion and convey some information. 2 A good protagonist: A good photo should have a protagonist who can attract people's attention. This protagonist can be a person, a thing, an animal, a landscape and so on. This protagonist is a carrier of theme expression. 3 Simple picture: A photo should be concise and clear. Only concise photos can better highlight the theme. Compression reduces distractions from the subject. After learning these three principles, you can observe, analyze and comment on a photo with a different vision from others-the photographer's vision. Of course, the above principle is only a beginner's principle for photographers. As your experience deepens, you will find other photos that violate the above principles. They have multiple themes or no themes, so there are no protagonists or multiple protagonists. You can take turns to take care of each theme, or take care of it selectively, or turn a blind eye. 2, the characteristics of the photographer's perspective ① What is the photographer's perspective, that is, the photographer's perspective on the subject, the way to see the subject is different from ordinary people, that is to say, the photographer's way to see the subject is the same as the camera. To be a photographer, ordinary people must approach the way they look at the subject with a camera in order to capture the subject you need. (2) Imaging principle: The human eye and camera look at things, and the images on retina and negative film are inverted images, but when people are in the examination center, they feel like positive images, which are formed through the transmission of brain nerves. At this time, the transmission process of brain nerves will be influenced by other nerves, weakening and canceling some objects that people don't need, and amplifying some objects that photographers pay attention to. This is what we often say. But the camera doesn't think, just records the subject truthfully on the negative according to the optical characteristics. So, when you see the photo, you will find that the image of the subject is either too small, or other objects and color blocks appear obviously in the photo, which grabs the line of sight and has to be attributed to the negative. The difference between the human eye and the lens is that the camera truly records all the subjects and is often influenced by people's emotions. 3. The photographer's understanding of the subject 1 Formal understanding: light: understanding of light, its intensity, direction, color, nature and meaning, in short, all the knowledge of light. Shadow: Light and shadow are interrelated. Shadow is not only an accessory of light projection, but also has a strong function of shaping three-dimensional sense and expressing texture, creating atmosphere, balancing the picture and forming a picture frame to add color to the picture. Color: Color makes the world full of energy and passion, which can make the picture colorful, but it can also make the picture chaotic. Color can affect people's mood, render the atmosphere and trigger association. Shape: that is, shape and appearance. All kinds of objects have their own shapes. If we can discover, summarize, refine and use the relationship between their shapes, we can produce dramatic effects. Quality: Texture belongs to the sense of touch in the human body, but vision can feel texture with the help of light, and the successful application of texture can make the picture have a second feeling-touch. (2) Technical understanding: The manifestations of photo motion are: a. Motion caused by the shift of the subject's center of gravity is reminiscent. B, the sense of movement from shooting skills. C, the record of motion trajectory. Distortion: Distortion of a normal subject through lens, mirror, special filter and other technical means. Its aesthetic characteristics lie in making people divorced from reality, purposefully strengthening and highlighting certain characteristics, and discovering the relationship between neglected phenomena in the past. Virtual reality: Virtual reality is a commonly used technique to express three-dimensional sense in photography. It makes the picture have a sense of depth, which can simplify the picture and highlight the theme. (3) perceptual knowledge perceptual knowledge, that is, the understanding of people, people are the most emotional. When you photograph people, you enter their emotional world and express their feelings. When shooting scenery and things, you should express the photographer's own feelings. Pay attention to people's happiness, anger, sadness, thinking, surprise, fear and sadness. (4) The understanding of artistic conception is a realm of blending scenes in literary description, that is, scenery, events and people have special significance in a specific environment. The understanding of artistic conception mainly depends on the photographer's own cultural accomplishment and rich cultural background. 4. viewfinder introduction 1 side view. Due to the separation of the visual axis between the viewfinder and the shooting lens, parallax causes the deviation between the viewfinder and the shooting result, and the parallax of the camera will be greatly increased in close range. In order to reduce the shooting error, the small camera added a line in the viewfinder to indicate the dislocation sign. ② Single-lens reflection framing: single-lens reflector and pentaprism optical framing system. No parallax, shoot whatever you see. The mirror reflects all the subjects to the top of the camera, and the pentaprism device converts the image into a positive image.
