Answer; As a shooting method, silhouette can be used for many purposes, which requires photographers to use it flexibly in creative techniques and innovate in creative ideas. So how to take a good silhouette photo? 1. Fully show the physical features of the silhouette theme, and vividly combine the modeling with the background. It can be said that the shape is the language and the background is the intonation, and this language is sometimes louder than silence, which is the beauty of silhouette photos. Because in silhouette photos, the subject has no color and details, so the physical characteristics of the theme are very demanding, which requires the author to carefully choose the shooting angle and subject shape according to the effect of later performance, fully display the external characteristics of the theme, and strive to be beautiful and vivid. 2. The acquisition of silhouette photos makes full use of the light difference between the theme and the background. Generally speaking, you can use backlight at sunrise and sunset, because the light at this time is the softest and looks not dazzling, which is a good time to shoot, usually only about ten minutes. In addition, we can make use of the artificial light difference between outdoor and indoor or the natural reflection of the sky and water. 3. Exposure should follow the principle of "less than the total", and spot metering should be carried out according to the bright part of the background, which makes the subject seriously underexposed and forms a strong silhouette. 4. When the proportion of the subject in the picture is too small or the picture is blank and monotonous, silhouette can be creatively used as the foreground. Black silhouette can not only oppress the audience's vision of the subject, but also not distract the audience. We can even use the silhouette as the main frame to form square, round or varied shapes, so that ordinary scenery has a unique sense of form and increases the depth of the picture. 5, long focal length If you use a 135 camera to shoot, you should choose a lens with a focal length of 85 to 135 mm. Because a lens with a shorter focal length (less than 50mm) often exaggerates people's five senses, when you use a lens with a focal length of 85 to135 mm, it will compress the perspective and make the five senses present the correct proportion. If you want to use a lens with a long focal length of more than 200mm, it will make your face look very peaceful. So it's better to take portraits with a medium telescope. What additional mirrors are commonly used in black and white figure photography? In black-and-white figure photography, the commonly used additional mirrors in front of the camera lens include two series: changing the color and light properties and changing the imaging and shadow. The former, such as various color filters, sky filters, ultraviolet mirrors and sky mirrors, and the latter, such as soft mirrors, halo mirrors and close-ups, are described as follows: (1) Additional mirrors 1 are often used to change the properties of colors and light. Various color filters are refined from colored and optical glass, including yellow, green, red, orange and blue respectively. Its function is to prevent or reduce unnecessary colored light and relatively increase the luminous flux of needed colored light, thus changing the color sense of photosensitive film. In black and white figure photography, yellow filter is the most commonly used. For example, in the case of blue sky and white clouds, shooting outdoor people, once used, can absorb part of blue light, make the blue sky on the film less sensitive, make the sky slightly darker, and the white clouds in the photo are obviously prominent; Otherwise the blue sky and white clouds will be mixed. Become a white sky, dull and tasteless. The yellow filter can also enhance the texture level of characters and show delicate and realistic skin color. It also has the characteristics of large light transmission range and low light blocking rate. So if you add a light yellow filter, you only need to open half the aperture. If you add a medium yellow filter, you only need to open one aperture. 2. Sky filter This is an additional mirror, half of which is yellow or light gray, and the other half is transparent and colorless. Because the edge of its colored part becomes colorless and transparent from deep to shallow, it is also called gradient filter. Its function is to adjust the contrast between the sky and the ground. Specifically, the colored part can absorb the purple and blue light of the sky or weaken the brightness of the sky, limit the exposure of the sky part on the film, and make the ground part more exposed on the film. When in use, the colored part should face upwards, and there is no need to increase the exposure. It is ideal to add a sky filter when shooting people in backlight. 3. Most UV mirrors and sky mirrors are colorless, and some are yellowish; The celestial mirror is close to colorless or reddish. Their main function is to absorb ultraviolet rays in the atmosphere. Ultraviolet rays have a serious impact on mountain photography and often hinder the clarity of images. After adding UV mirror or sky mirror, the influence of ultraviolet light on the photosensitive plate can be eliminated, and the image clarity can be improved, especially for distant scenery. Because the UV mirror and sky mirror are colorless or close to colorless, there is no need to increase the exposure under any circumstances, and there is no side effect on photography, so they are often added to the lens for protection. (2) Changing the role of the additional mirror 1 and the soft lens commonly used in imaging and imaging is to partially refract the light passing through the lens, so that the photographed image can maintain a certain clarity and the contrast can be softer and more natural. Soft mirror has many structural forms. Generally, circular ripples with different densities are made on transparent glass, or meshes woven with nylon wires or other fibers are made to achieve the purpose of splitting and refracting incident light. After wearing a soft lens, taking close-up photos of women and children can make the images soft and pleasing to the eye. 2. The shape and structure of the halo mirror is a round hole in the middle of the glass lens, and the periphery is sandy. Because the middle is hollow, wearing it in front of the camera will not affect the focus of the main image. When shooting a person, you can get normal clarity by arranging the face in the position of a round hole, but the images around the face are hazy and dizzy because of the influence of sand on the lens. When wearing a halo mirror to shoot people, you should use a single-lens reflex camera because the photographer can directly observe the image halo through the viewfinder of the camera. 3. The myopic lens, also known as the bust, is a convex positive lens. After wearing it, the focal length of the lens can be shortened, thus shortening the nearest photographic distance, expanding the image of people and making full use of the area of photosensitive film. There is generally no need to increase the exposure when shooting, but a small aperture should be used to increase the darkness to prevent the four corners of the film from loosening. In photography practice, close-ups are not suitable for close-ups of people, because the photography distance is close and it is easy to produce deformation defects. In addition to the above-mentioned commonly used additional mirrors, there are many additional mirrors with special effects, such as multi-shadow mirror, starlight mirror, medium gray mirror and so on. After being added, the former two can obtain multi-image and different radial light effects respectively, and the latter can reduce the luminous flux. What is the portrait photography here? What is the key to the success of figure photography? People photography is a kind of photography that takes static or dynamic people as the shooting object, and focuses on depicting their appearance and mental outlook, thus directly expressing the people. All kinds of subjects involving figures and taking figures as the main body belong to the category of figure photography. Such as: portraits, family life, gatherings of relatives and friends, mutual affection between lovers, wedding etiquette, childhood documentaries, campus dynamics, night scenes of the elderly, travel scope, fashion clothes, stage performances, sports activities, workplaces, festivals, local customs, social news, body art, etc. , a wide variety, you can choose anywhere. Generally speaking, in the field of photography art, besides portrait photography, there are many kinds of photography such as family, children, travel, wedding, sports, stage, social documentary and even human body, which have their own characteristics and are interrelated, and often belong to the series of portrait photography, collectively referred to as portrait photography. Since the birth of 1839 photography, people have always been the main body of photography, and the key to the success of figure photography is to have both form and spirit. In real life, everyone's appearance and personality characteristics are different, and their mental outlook is ever-changing. A photo of a person, if it captures the expression and emotion of the subject, has a poor appearance, can't stand scrutiny and lacks due artistic expression; On the other hand, if the appearance is similar, but the expression and emotion are not portrayed, then the performance of the characters must be bland and have no lasting appeal. Therefore, people's photography can not be limited to taking pictures, but should make full use of the advantages and disadvantages of people's appearance according to the theme and highlight the aesthetic feeling, so as to better convey and depict people's mental outlook through their appearance and make people in photos look more beautiful, vivid and energetic than the real subjects. Only by being "similar" can we be vivid. In order to make people's photography meet the requirements of "having both form and spirit", photographers should not only correctly master the camera use technology, but also observe and study excellent photographic works and related photographic knowledge, and often observe and think carefully about all kinds of people in life, so as to cultivate agile thinking and judgment ability. In this way, in the practice of people's photography, they can be thorough and innovative, seize the opportunity to choose the subject, and seize the typical and vivid moments of the subject to shoot one after another. Second, what are the shooting methods of figure photography? The shooting method of figure photography is nothing more than posing, snapping and combining posing. They have their own characteristics and requirements, which are interrelated and cooperate with each other to form an indispensable modeling technology for figure photography. 1, posing means that during the whole shooting process, the subject is always fully aware that someone is taking pictures of himself, so that the photographer can have enough time to finish shooting after preparing for shooting and manipulating the subject. Therefore, this shooting method is also called compassion, or it can be called subject omniscient shooting method, which is adopted by portrait photos, group photos, commemorative photos, advertising photos and so on. But in the case of being pushed around, the photographer should try to relax the mind of the subject in order to cooperate with the shooting. 2. Snapping means that during the whole photographer's process, the photographer directly captures the typical and vivid moments in the character activities without letting the photographer know that someone is taking pictures of himself. So it can also be called the shooting mode that the subject doesn't know. This way of shooting, composition and light consumption may not be satisfactory, but the subject is in an unrestrained state of activity and has a natural manner. But the subject needs rich life experience and keen eyesight. In all kinds of fleeting character activities, he is good at grasping the most typical, perfect and eye-catching moment of the subject and pressing the shutter in time. 3. The combination of swing and grab means that during the whole photography process, although the subject knows that someone is taking pictures of himself, he does not tell the exact shooting time, so that the subject's attention can still be focused on what he is doing, and the photographer can have a certain time, choose the best angle and light, and press the shutter at an appropriate time after a small range of adjustment and layout. This shooting method combines the advantages of posing and capturing, so that there is a swing in grasping and a grasp in swinging. So it is also called shaking and grabbing, or it can be called a half-baked shooting method. For your reference, thank you.
