Little knowledge of photography
Here are some photography tips: 1. ** Exposing Control ** - The camera controlled the exposure through the aperture, shutter, and the USB. These three were called the three elements of exposure. - The aperture size affected the brightness and clarity of the screen. A large aperture (such as f/1.4) had more light, which was suitable for low-light shooting and background blurring. A small aperture had less light, and the clear range was larger. - The shutter controlled the time the light stayed in the camera, determined the length of exposure, and affected the sense of motion in the picture. - The higher the value, the brighter the image. 2. ** Composing Skills ** - The basic composition included the rule of thirds, symmetries, and guiding lines. The rule of thirds was to divide the picture into nine areas and place the subject at the intersection point to balance the picture; the symmetrical composition was to place the subject in the middle of the picture; the guide line composition used line elements to guide the viewing angle. - There was also a four-square blank composition (suitable for half-body portraits, the top three squares of the picture were left blank, and the characters were placed in the same four-square), a diagonal composition (the background or characters were composed along the diagonal line to make the photo vivid and natural), a triangular composition (the half-body portrait could have the eyes stuck on the top line, or let the picture elements be triangular for sitting posture to show the length of the legs), and so on. - When shooting a character, the half-body, full-body, and close-up should be controlled to ensure the integrity of the image. It was necessary to avoid the image being cut at the key points of the character (such as the neck, knees, etc.), and to avoid placing objects on the head of the character or crossing the neck. Generally, the main body was placed at the three-point line (the four focal points of the nine-square grid) or in the middle. The main body could be emphasized to make the picture feel spatial and balanced. 3. ** Light usage ** - The art of photography was the art of using light. Light was divided into natural light (sunlight, moonlight) and artificial light (lighting, flash, etc.). To understand the characteristics of different lights and take targeted shots, such as sunrise and sunset, studio portraits, etc., one needed to master the use of light. - To understand the camera's white balance and color temperature, different light sources (incandescent lamps, fluorescent lamps, sunlight, etc.) will bring different colors to the photo. Adjusting the white balance can make the color more accurate and realistic. 4. ** Other Points ** - Hold the camera or phone firmly with both hands to avoid blurring the picture when shooting. - Focus must be accurate, prioritize autofocus, manually focus when there is insufficient light, and click on the screen to focus. - When shooting characters, one had to pay attention to their expressions and postures to avoid ugliness. - Pay attention to the horizontal and vertical of the image (except for the special wide-angle distortion effect). - The image had to be simple and clean, removing items that did not need to be integrated into the image. - The appropriate post-processing (color mixing, cutting, etc.) could enhance the work, but it could not be overly embellished.

Basic photography knowledge
Here are some basic photography knowledge: 1. ** Equipment selection **: If you just want to experience photography, a portable camera can satisfy your needs. If you want to learn photography in depth, you can use a mobile phone or portable camera to learn composition, lighting, and post-color adjustment skills. After you have some experience, you can buy a professional camera. 2. [Familiar with the equipment: The camera manual is a good helper for understanding the operation of the camera. Many basic operating knowledge is introduced in detail in the manual.] 3. [Find the subject: Don't think that beautiful scenery is only in the distance. Pay attention to the details around you and be good at discovering the shooting materials around you.] 4. [Focus on practice: No matter how many photography works and tutorial you read, it's not as rewarding as going out and taking real shots.] 5. ** Imitate excellent works **: By imitating the composition and lighting techniques of excellent photography works, you can effectively improve your photography skills. 6. ** Master Shooting Techniques ** - ** Stabilizing Equipment **: Hold the phone or camera firmly with both hands to avoid blurring the picture due to shaking during the shooting process. - ** Precise Focus **: Use autofocus first. When there is insufficient light, you can focus manually. Focus on the subject. - ** Pay attention to the details of the character shooting **: Pay attention to the expression and posture of the character when shooting the character, ensure the integrity of the character's image (control the half body, whole body, and close-up), avoid cutting the key points of the character (such as the neck, knees, ankles, fingers, etc.), and pay attention to not placing sharp objects on the head of the character or crossing the neck. - ** Control the exposure **: Make sure the image exposure is accurate. It can't be too dark or too bright. The phone will usually adjust automatically. - ** Maintain Level **: When shooting objects such as buildings, pay attention to maintaining the horizontal line horizontally and vertically (except for special wide-angle distortion effects). - ** Balance the main body of the picture **: You can use the nine-square grid composition, the middle composition, and other methods to place the focus of the shooting on the three-point line or the four focal points of the nine-square grid, or place the main body in the middle position to avoid the main body being in the corner. - ** Keep the image simple **: Remove unnecessary items from the image to make it simple and clean. - ** Choose a suitable angle **: Try shooting from a variety of angles, such as up, down, squatting, and lying down. Don't just shoot from a standing position. - ** Depth-of-field effect **: Make good use of the depth of field function of the phone to highlight the main body of the picture and blur the messy picture through the small depth of field. - ** Using white space technique **: avoid too many elements entering the picture, adhere to the principle of minimalism, use white space to make the picture clean and tidy, and highlight the subject. - ** Use line composition **: Find the lines of the object to be photographed, and use cross-composition, parallel composition, and other methods to take an orderly and regular picture. - ** Use frame composition **: Place the character in the frame of a door or window, and guide the line of sight into the frame to highlight the main body. - [Use Light]: Learn how to use light such as backlighting, fairing, and silhouette. 7. ** Post-processing **: Simple computer post-processing such as color matching and cutting can help to improve the quality of the work, but it cannot be overdone. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Basic knowledge of photography
Lectures on basic photography usually covered many aspects. In terms of cameras, it would involve the classification of cameras. For example, according to the framing method, it could be divided into single-lens head-up framing (CP) cameras and single-lens reflex (TF) cameras; according to the film size, it could be divided into 135 cameras, 120 cameras, etc. It also explained the characteristics of different types of cameras, such as film cameras and digital cameras. Film cameras recorded images using the properties of the silver Halide that turned black when it came into contact with light, while digital cameras were different from film cameras. Regarding photography techniques, the concept of depth of field was mentioned, including large depth of field (the subject and background are clear, often used for group photos, meetings, events, landscape photography, etc.), small depth of field (only a part of the picture is clearly shown, the rest is blurred, often used for portrait photography), and soft focus (no part of the picture is 100% clear, often used for shooting beautiful women). It would also include knowledge of light usage and composition techniques. For example, in composition, one had to use various scenes and perspectives to search and shoot in all directions. In terms of light usage, one had to understand the most essential modeling elements of photography--light and shadow, so that the two-dimensional photos would have a three-dimensional sense. In addition, the lecture might also talk about the history of photography, the basics of art, and encourage participants to use creative thinking to try different styles of photography. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Sculpture photography knowledge
The following is some knowledge about sculpture photography: ** I. Thesis and Concept ** 1. ** Outstanding Sculpture ** - The uniqueness of the sculpture had to be identified, such as its shape, material, cultural significance, or its relationship with the surrounding environment. If it was an ancient style bronze sculpture, it might be necessary to emphasize its quaint texture and traces of time. If it was a modern abstract sculpture, it would be necessary to capture the artistic sense conveyed by its unique lines and shapes. 2. ** Consider background and environment ** - The background and environment can enhance or complement the theme of the sculpture. For example, when shooting sculptures on the streets of a city, the surrounding buildings, pedestrians, and street scenes might be part of the picture. If the sculpture was located in a park, natural elements such as green trees, grasslands, and lakes could echo with the sculpture and form a harmonious picture. ** 2. Shooting angle and composition ** 1. ** Try from multiple angles ** - Shooting sculptures from different heights and directions would produce different effects. A low-angle shot could make the sculpture look taller and more majestic, while a high-angle shot might show the full picture of the sculpture and its relationship with the surrounding environment. Different directions such as the side, front, and back of the sculpture could also present different characteristics of the sculpture. For example, the front of some sculptures was their main display surface, while the side may have unique veins or lines. 2. ** Principle of composition ** - Follow the basic composition rules, such as the rule of thirds. Placing the sculptures near the four intersections of the picture would make the picture more balanced and beautiful. He could also use frame composition to frame the sculpture using the surrounding elements (such as the doors and windows of the building, the branches of the trees, etc.) to guide the audience's attention to the sculpture. - It was to prevent the messy background from interfering with the main body. If there are too many distracting elements in the background, you can blur the background and highlight the sculpture by adjusting the shooting angle, using a large aperture (if the equipment supports it), and so on. ** 3. Use of Light ** 1. ** Natural Light ** - Natural light at different times would produce different effects. The low-angle sunlight in the morning or evening could bring long shadows to the sculpture, enhancing its three-dimensional and texture. Side lighting could highlight the texture and outline of the sculpture, making the shape of the sculpture more distinct, while backlighting could create a unique silhouette effect. If the outline of the sculpture was highly recognizable, backlighting could produce a very artistic picture. 2. ** Artificial light ** - Indoors or in dimly lit environments, artificial light could be used to illuminate the sculptures. For example, camera lights, flash lights, etc. Pay attention to the intensity, direction, and color temperature of the light to avoid creating strong shadows or unnatural colors. For example, the use of soft lights could make the light more evenly distributed on the surface of the sculpture, reducing the harshness of the shadows. ** 4. Equipment and Technology ** 1. ** camera settings ** - He adjusted the camera's parameters according to the shooting needs. If you want to capture clear details, you can use a lower IQ value.(For example, the shutter speed was adjusted to adapt to the shooting environment to avoid blurring the picture due to hand shaking or object movement (if it was a movable sculpture or there were dynamic elements around). The aperture size affected the depth of field. A large aperture (such as f/2.8 and other small aperture values) could blur the background, and a small aperture (such as f/8 - f/16) could make the entire sculpture clear. 2. ** Screen Selection ** - The wide-angle lens could capture the whole sculpture and the surrounding environment, which was suitable for showing the relationship between the sculpture and the environment. The telephoto lens could zoom in on the distant sculpture and compress the space to highlight the local details of the sculpture or avoid the crowd from interfering with the main shot. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Experience and knowledge of photography
The following are some of the photography tips and understandings: ** 1. Equipment ** 1. ** Avoiding bottom-line theory ** - For beginners in photography, they should not blindly pursue full-frame cameras. At present, the performance of mainstream cameras on the market was enough to support entry-level or even advanced photography creation. They should not fall into the concept of "one level is too big to crush people". They should not be overly entangled with equipment and affect their investment in photography itself. 2. ** Selection of camera lens and actual needs ** - Many beginners yearned for the camera's large aperture blurring effect, but sometimes they didn't know the actual degree of blurring they needed. When choosing a lens, the large aperture blurring effect could not be the only criterion. For example, although the blurring effect of the M4/3 frame camera lens behind the equivalent full-frame body was relatively weak, it might also meet the shooting requirements. Moreover, the large aperture lens was also beneficial to the image quality at night and guaranteed the safety of the shutter. 3. ** Cameras 'body characteristics ** - In terms of flipping screens, the side flip screen had more advantages than the 90-degree flip screen in some shooting scenes. For example, when the camera was low and the composition was vertical, the side flip screen was more convenient. ** 2. Shooting process ** 1. ** Multi-angle shooting ** - When you arrive at a scenic spot, you can't just take a photo and leave. You should walk around to observe and try different angles. For example, don't always take pictures from the line of sight. You can find more interesting angles by climbing high and low. For example, photographers sometimes lie on the ground to take pictures. Although they may be covered in mud, they can take pictures with different effects. 2. ** The importance of light ** - Light had a great effect on the quality of a photo, although it was sometimes difficult to explain to ordinary people. Even if it was sunny at noon or cloudy, there were reasons why it was suitable or not to take photos. Photographers might use tools such as flashes and mirrors to help with the shooting to deal with the lighting problem. 3. ** Backstory processing ** - When shooting (especially portrait photography), you can't just focus on the subject. The background is also very important. The background elements such as utility poles above their heads and trash cans next to them might ruin the overall effect of the photo, so the photographer needed to spend time dealing with the background and finding the right angle to shoot. ** 3. Concept of photography ** 1. ** No day off for photography ** - For a photographer, photography was a way of life and an attitude. A photographer was used to being ready to capture the decisive moment at any time. There was no such thing as the so-called "off-duty" state. 2. ** Pressing the shutter is not the end ** - In addition to the pre-shooting, there was also post-production work, including software post-production and conversion into a suitable medium (such as online publishing or physical printing). You couldn't think that uploading to social media immediately after taking a photo on an iPhone would complete all the photography. ** 4. Regarding the value of the camera and the quality of the photos ** 1. ** The relationship between expensive equipment and good photos ** - Having an expensive camera didn't mean that you could take good photos. Just like buying a piano didn't necessarily make you a pianist, you couldn't think that someone was a master photographer just because they had "professional equipment." 2. ** Different equipment has value ** - Whether it was a full-frame, APS-C, M4/3, one-inch card machine, or a mobile phone, whether it was a Hazel, Lycra, Fuji, Ricoh, and other brands of equipment, they could not directly determine the value of a photo. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Huawei Maimang 5 photography knowledge
The Huawei Maimang 5 had many features in terms of photography. It was equipped with a rear optical image stabilization 16-million-pel BSI (back-illuminated) camera, a F2.0 large aperture, and a large sensor. It could perfectly capture low-light, high-light, high-contrast, and other difficult scenes. It supported three-axis optical image stabilization, and through the built-in thermometer to detect hand shake and reverse correction, effectively improving the quality of shooting in dim light, and could also take high-quality photos under dim light sources. In terms of functions, the frame of the Maimang 5 was simple and easy to use for the first time. It provided real-time beauty 2.0 with eight templates. The special features included online translation, slow-motion shooting, intelligent recognition, gourmet/beauty, and the streamer shutter function. The streamer shutter provided four types of scene shooting, which could shoot silk flowing water effects. The front 8-million-pel camera had the "Charm Me" selfie function with the support of EMUI4.1. By taking photos from different angles of the face, the facial details could be adjusted. The default skin beauty mode provided 1 - 10 levels of beauty. From the actual shooting effect, the blue sky was restored accurately during daytime shooting, and the resolution of the center and edge of the picture was excellent. In the night scene shooting, the buildings were exposed, the sky was pure and noisy, and the street lights were well controlled. The dynamic range performance was satisfactory in the scene with high light ratio, and the light and dark parts could be taken into account. However, the night sample of the same scene may have a slight reduction in resolution, but the details were still at the same price. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Video of photography knowledge, lecture video
There was a video about photography titled "This video tells you how to improve your aesthetics.| The main content was to improve the knowledge of photography aesthetics, including how to understand a work (from the composition, light and shadow, color, clothing, movement, photographer's thoughts, expression, etc.) and the ways to obtain high-quality works (such as reading books, reading magazines, watching movies, watching world famous paintings, etc.). This could be used as a reference for photography knowledge video lectures. In addition, there was a video titled "Photoshoot tutorial #photography #photography tutorial #photography training tutorial #photography skills #photography tutorial #photography tutorial". It mainly talked about the photography skills of using two lights to shoot a boy's portrait. It could also be used as a reference for photography knowledge videos and lectures. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Mobile photography tutorial cloud knowledge
Here are some tips on cell phone photography: ** I. Pre-shooting preparation and basic settings ** 1. ** camera mode ** - When you turned on the professional mode of the phone, you had to adjust the camera's parameters such as the camera's sensitivity, shutter speed, aperture, and white balance. 2. ** Light usage ** - ** Shun Guang **: When the sun is directly opposite you, it is suitable for shooting clearer objects. - [Backlight: With the sun behind you, it can outline the outline of a person and make them stand out.] - [Backlight measurement: The sun is on the side, which can increase the atmosphere of the photo and emphasize the theme.] ** Two, composition skills ** 1. ** Common composition methods ** - ** Third-division composition **: Place the subject in one-third of the picture and leave the remaining two-thirds blank. This composition method is more commonly used and can make the picture simple and the subject prominent. - Centered composition: Place the subject in the middle of the photo, but pay attention to the white space around the subject. - Diagonal composition, triangle composition, guide line composition, frame composition, and so on were also common composition methods. 2. ** The aesthetic logic of the composition and the blank space ** - It was important to understand the aesthetic logic of composition. There was no need to memorize the terms of composition. All compositions were inseparable from white space, which could balance the picture and inspire the reader's imagination. The position and proportion of white space in the picture were closely related to the composition of the photo. White space had many functions, such as emphasizing the main body and making the picture simple; when the white space was smaller than the main body, the photo would be more realistic; when it was larger than the main body, it would be more freehand; it could also increase the reader's imagination. ** 3. Shooting Techniques for Special Scenes ** 1. ** Shoot the big tree ** - You can use a wide-angle lens to get close to the tree trunk and use the tree trunk as the background to increase the layering. You could also step back and place your phone on the ground to take a picture from below. With shadows and mottled light, the tree would look even more shocking when you took a picture from above. 2. ** Ground Treatment ** - If the ground looked good, he could bring it into the picture. If it didn't look good, he could point the camera upwards to avoid interference from the ground when the tree crown was big. When the branches were sparse, he could use the branches as the background to bring the distant sky and sea. 3. ** Shooting a tree ** - When there was light, he used the contrast of light and shadow to increase the three-dimensional sense and beauty. He could narrow down the scope of the camera and take a direct shot of the tree, or wait for a beam of light to illuminate one of the trees as the main body. 4. ** Using water to shoot ** - When the lotus flowers wither in autumn, you can narrow down the range to shoot the remaining lotus lines. Using the reflection of light and shadow on the water surface to create a dreamy atmosphere, shooting reflections in the water without physical trees can increase the artistic sense. 5. ** Shooting in a chaotic environment ** - If there was a main object, use a large aperture and shallow depth of field effect, focus on the main object to make the background blur to highlight the main object; if there was no main object, narrow the scope to make the picture elements as uniform as possible and add light and shadow. 6. ** Wrapping composition ** - Choose an obvious main body or embellishment to be placed in the middle of the picture or in an important position to increase the attraction and visual impact. ** 4. Post-processing ** - You can use the butter camera to process the pictures, and use software such as Pics Art, Snapseed, Mix, and Wake Up to color and refine the pictures. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Calligraphy, painting, photography, professional knowledge
** 1. Calligraphy Professional Knowledge ** 1. ** Creation related ** - The laws of calligraphy creation included copying, thinking, and creation. The "thinking" part was often neglected, but it played a role as a bridge between copying and creation. In the creative process,"meaning" was the dominant factor, and "meaning" was the archetype image of the creative method in the brain. - Beginners had some things to pay attention to, such as choosing ink for beginners, suitable for writing inscriptions, small regular script could not hang elbows, big regular script could not pillow wrists, Lanting could not enter the door, holding the pen could not be too tight, the structure could not be uniform, and the strokes could not be the same. 2. ** Calligraphy Status Judgement (Take Qi Baishi as an example)** - From a traditional point of view, Qi Baishi was more regarded as a master painter because his paintings were the main part of his artistic career. However, his calligraphy works were unique in the application of brush strokes and form innovation. Although it was insufficient under the traditional calligraphy standards, if calligraphy was regarded as a part of his multi-talented, combined with his painting achievements, he could be regarded as a "master of calligraphy and painting." 3. ** Research Focus ** - The creation theory in calligraphy theory should lead the research and analysis from the traditional objects such as strokes, structures, and chapters to the main body of creation. Not only did he have to pay attention to the result of the work, but he also had to study the complex psychological process before the work was formed. - In the copying process, we should pay attention to the psychological training of creative personality, put observation, perception and judgment into it, and interpret the mental training in the early stage of creation from the perspective of "the deepening effect of searching for love". ** 2. General knowledge of painting (not too much painting content, only part of painting knowledge is reflected in the relationship between art and photography)** - Art students had a good foundation in composition, a unique understanding of color, and knowledge of sketching light and dark contrast. These were very helpful in photography. For example, art students had advantages in composition and color in the photography art exam. ** 3. Professional photography knowledge ** 1. ** In terms of composition ** - The use of lines was an important method of photography composition, but it required a strong sense of observation. Exaggerated ratio comparisons were easy to surprise, and ultra-low camera angles allowed good visual effects to be found from different angles. 2. ** Painting and Calligraphy Equipment and Techniques ** - ** Equipment **: Requires a professional single-lens reflex camera, fixed-focus lens (good quality, avoid using wide-angle lens and telephoto lens), at least two flashes (natural light can be used without flashes), wireless flash synchronization device (required when using flashes), tripod (must be used, not hand-held shooting), shutter release. - ** Shooting preparation and operation method (with flash)** - Prepare a photographic backboard (such as a wooden board) to fix the painting and calligraphy works. If not, find a white wall. The two of them will flatten the painting and calligraphy works close to the wall with their hands; support the tripod and fix the camera; support the flash light. Light a lamp from the left and right sides at a 45 - 50 degree angle to ensure that the light received by each part of the painting is consistent. - The camera lens was facing the center of the painting and calligraphy work. The camera was placed properly, and the lens was parallel to the wall. It was best for the camera to be more than 5 meters away from the work (the focal length of the full-frame camera lens was between 50 - 85 fixed-focus lens). Use the manual exposure mode to adjust the aperture, shutter, and sensitivity. - ** Using three flashes to shoot Chinese calligraphy and paintings on four-foot-long white Xuan paper (Traditional camera with film of 100 ° C, digital camera with sensitivity of 100 ° C)** - Aperture f11, 1/125 seconds, exposure compensation + 1 - 2 level RV value; when shooting dark-colored rice paper paintings, exposure compensation should be based on the situation- 0.3 - 1 level RV value; use the focal length of the lens to shoot with a focal length of about 100mm, and the shooting distance should be between 3 - 6 meters according to the size of the painting. - ** The camera settings when shooting paintings (under normal lighting)** - The camera lens was aimed at the center of the painting and calligraphy works to illuminate the front of the painting and calligraphy works. A flash was installed on the top of the camera as a flash light, and two flashes on both sides were used as synchronized flash lights. The focal length of the three lamp heads was adjusted to the wide focal length to ensure uniform illumination. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
photography knowledge white plus black minus
White plus black minus was an important principle in photography. The camera's light measurement system used 18% gray reflection as the exposure standard. When the light was measured at 18% gray, the image exposure was normal. However, when shooting white and other high-light scenes (that is, scenes with a reflection rate higher than 18% gray), the camera would automatically reduce the light in order to achieve the standard 18% gray reflection rate, causing the white image to be gray, similar to underexposed. At this time, it was necessary to increase the exposure compensation (that is,"white plus") to improve the situation of insufficient exposure of the picture, so that the white and other highlights of the picture returned to normal. On the contrary, when shooting a darkened scene (the reflection rate is lower than 18% gray, such as a pure black scene), the camera will automatically increase the brightness to reach the reflection rate of 18% gray, causing the pure black scene to be not black enough, like overexposed. At this time, it was necessary to reduce the exposure compensation (i.e.,"black reduction") so that the image was no longer overexposed and the colors of the darkened scene were normal. This principle helped to interfere with the possible errors in the camera's light measurement through exposure compensation when shooting high-light images or darkened photos, so as to obtain the ideal shooting results. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
