Use the lens to preserve historical memories
Photographs were a powerful way to preserve historical memories. The camera could capture many aspects of human life, culture, society, and the natural environment. Photographers used their cameras to freeze the moment, thus recording important moments in the course of history. For example, the U.S. Navy Soldier on the Valkyrie, taken by the American photographer Joe Rossenthal, recorded the moment when the U.S. Navy soldiers raised the flag on the Valkyrie during World War II. This photo became a famous photo in American history. Walker Evans 'subway station photo recorded the life scene of people in the New York subway station in the 1930s. It was very representative. Apart from important historical moments, photography could also record human life and culture. For example, the Chinese photographer Li Xueren's " People in the Three Gorge " photo showed the life style of the people in the Three Gorge area of China and became a classic in the history of Chinese photography. The American photographer Annie Leibovitz's " American Family " photo recorded the scenes of American family life and was very representative in the history of American society. Not only did photography record history, but it could also convey information and emotions. Through photos, we can see the lives and cultures of people from different cultures, regions, and eras, and feel their emotions and thoughts. For example, the photos taken by the French photographer Henri Cartier in the streets of Paris let us feel the life and cultural atmosphere of the people of Paris in the 1930s. In the early days of human society, the ancestors began to record history, but the early methods were more primitive, such as word of mouth, knotting ropes, and so on. The emergence of words, paper, and printing improved the level of recording history. After the introduction of the camera in the mid-19th century, images became a new way to record history.

How to use the lens distortion plug-in
The following is how to use the software lens distortion plug-in: - In PS, the lens distortion could be corrected and repaired through the lens configuration file or manual adjustment. - In Unreal Engine 4.24, you can use the "Opencv Lens Distortion" plug-in to correct lens distortion. The steps are as follows: - Open the Plugins window, search for "Lens Distortion", enable the "Open LV Lens Distortion" plug-in, and restart the project. - To simulate or correct the camera distortion, you first need to perform a camera correction to calculate the camera's internal parameters (the camera's internal parameters mainly include the radius and the thickness of the distortion, the vertical and horizontal focal lengths, and the position of the optical center on the final image). The plug-in is based on the default camera correction method of the Open CVs, Zhang Zhengyou's method. It provides two methods of calibration. One is to use a picture file for calibration. That is, a set of pictures containing checkerboards (the combination of checkerboards must basically cover the entire picture and the picture must be clear) is input to the Calibrator. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
What's the use of a camera lens?
The camera lens was the most critical equipment of the video system, and its quality (index) directly affected the overall performance of the camera. The lens was equivalent to the crystalline lens of the human eye. Without the lens, the image output from the camera would be a vast expanse of whiteness. There would be no clear image output, which was consistent with the principle of home cameras and cameras. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to use the lens in cultural photography
In cultural photography, there were many ways to use the lens: ** I. Use of a telephoto lens ** 1. ** Suits the situation ** - It was more suitable for people who were not good at communication to sweep the streets. For example, with a 70 - 200mm lens, one could shoot a scene of a grandfather and grandson playing in the river from a distance through a gap in the tree, or wait on the other side of the river to shoot a unique character on the steps. - He could not disturb the subject from a distance and had enough time to consider the composition. - It has a strong ability to express the details of the character, making the details of the character's face clear and obvious. It can also compress the space, simplify the background, and highlight the main character. 2. ** Inadequacies ** - When taking photos of people sweeping the streets, the image would give people a sense of distance and lack a sense of communication with the target. ** 2. Use of the wide-angle lens ** 1. ** Suits the situation ** - The 35mm fixed-focus lens was known as the best lens for humanity. Using a wide-angle lens to capture human culture required courage and strong communication skills. - From a slightly further distance, many elements of the scene could be captured into the picture, and the background could be used to reveal information such as the identity of the character. - When shooting at a close distance, there would be no spatial distance barrier in the picture. One could feel the breath of the conversation with the subject and feel the other party's state more directly. The sense of communication between the pictures was strong. At the same time, more picture information could be shot at a closer distance. It could not only highlight the main character but also tell the story of the scene. 2. ** Inadequacies ** - The distortion of the picture was obvious, and it would be severely distorted around the edges. When shooting, try to hold the camera flat, and don't arrange the characters too far away. However, you can also use the distortion to express your thoughts. ** 3. Use of other lenses ** 1. ** Standard lens (50mm)** - The perspective of the picture was close to the human eye's observation effect, which was good for composition. - It provides a certain blurring effect and can use the shallow depth of field to highlight the theme of the picture. For photography beginners, when shooting on the street, it can maintain a certain distance from the subject to improve the success rate of shooting. 2. ** Portrait lens (such as 85mm, 135mm, etc.)** - It can be used for cultural photography, and can be selected according to the shooting needs. 3. ** Super wide-angle lens (such as 16 - 35mm)** - It can be used for cultural photography according to the actual equipment, such as when it is necessary to show the living environment of the subject, the tall buildings in the background, and other elements. In short, the use of cultural photography lens needed to choose the appropriate lens and shooting method according to the photographer's own characteristics (such as whether he was good at communication), the purpose of the shooting (such as emphasizing the details of the character or showing the scene story), and the image effect that he wanted to create (such as whether there was a sense of distance or whether special image distortion effects were needed). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Use and maintenance of the single-lens reflex camera
The usage of the DSLR: - [Exposing Mode: Understand exposure modes such as M and P.] The P-mode was automatic, and the camera would automatically set the shutter speed and aperture to obtain the best exposure. It was suitable for taking shots or when there was no time to adjust the camera settings. Although the exposure could not be changed, the exposure parameters could be selected independently. The M-mode was manual mode, and the user could completely control the shutter speed, aperture, sensitivity, etc. For example, setting the shutter speed to B-door or remotely controlling B-door could achieve a long exposure. - Different shooting scenes: When shooting portraits, use a large aperture (within F5.6) and a focal length of 50mm or above. The shooting distance is determined according to the full body, half body, and head shot to achieve background blurring. You can choose the audio file for shooting scenes, use an appropriate aperture (above F8), and the focal length can be freely selected. However, it may be easy to produce distortion when shooting with a wide angle. DSLR maintenance: - Cleaning: - After each use, clean the lens and the outside of the camera with a soft brush, especially around the interface and switch buttons. - Regular cleaning. It is recommended to thoroughly clean the DSLR camera every 3 - 6 months. Use a dust collector to remove dust from the lens and the interior of the camera (professional dust collectors are recommended). Gently wipe the inside and outside of the camera with a rubber brush (avoid touching the lens and sensors). Use professional cleaning solution to clean the lens and the exterior of the camera to remove fingerprints, oil stains, and dirt. - The cleaning of the camera should be comprehensive, and the corners should not be missed. As for the coating in front of the lens, because it is very thin (0.0001mm), it will be damaged if it is wiped often. You can add a UV-lens (anti-oil, dust-proof and easy to clean). When cleaning the lens, camera or sensor, you must use special cleaning tools. - Other maintenance: - Dust-proof: In dusty places, use your hands, lens cap, or soft cloth to block the lens; before departure, determine the commonly used lens and install it properly. If you need to change the lens, find a leeward place to quickly change it. Hold the lens barrel and rotate it without moving. - Shockproof: The camera and lens are fragile. When in use, avoid physical damage such as impact and falling. When not in use, put it in a camera bag with an air cushion. - Anti-humidity: In areas with high humidity or during the rainy season, you can buy a waterproof box (maintaining 40% - 50% humidity) to store the camera and accessories. If you don't have any conditions, you can buy a drying agent or color-changing silica gel to dry it. Try to avoid shooting in rain and snow. - Magnetic Field Protection: The camera should be kept away from electrical appliances with strong magnetic fields such as televisions, radio, refrigerator, and microwave to prevent the lens aperture blades from being magnetized and the memory card data from being lost. - High and low temperature protection: When shooting at low temperatures (such as-30 ° C), prepare more batteries to keep warm. In summer, avoid putting the camera in the trunk of the car to prevent the battery from bursting. - Water-proof and anti-glare: avoid shooting on rainy days. If you have to shoot on rainy days, you can bring a waterproof camera bag. When shooting, use an umbrella or plastic to protect the lens. Do not shoot directly under strong light for a long time to avoid burns on the sensor. - Batteries and memory cards: If you don't use the camera for a long time, clean and remove the batteries and memory cards before storing them, and place them in a dry and cool place. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The single-lens reflex scanner or camera is in use
The description you provided is not very clear. If you want to know some precautions or operation points when using an DSLR scanner or camera, the following information may be helpful. For a DSLR camera, one must first be familiar with the basic operations of the camera, such as the various buttons and functions (like the shutter button, the mode dial, the exposure compensation button, etc.), master the installation and removal of the lens, and properly install the battery and memory card. Choosing the appropriate shooting mode was crucial. The automatic mode was suitable for beginners, the aperture priority mode could control the aperture size to adjust the depth of field, which was used to shoot portraits, flowers, and other prominent scenes. The shutter priority mode was used to control the shutter speed and was suitable for shooting moving objects. The manual mode was suitable for experienced users with specific creative needs. In terms of composition, you can use the principle of three-point division to divide the picture into nine squares, place the main body on the intersection or line, and try different angles at the same time (top, top, side, etc.). Also, pay attention to the simplicity of the picture to avoid messy elements interfering with the main body. In terms of exposure control, one had to adjust the aperture size reasonably (the larger the aperture, the more light would enter, the lighter the depth of field, and vice versa), the shutter speed (the slower the shutter speed, the more light would enter, but it would be easy for the hand to shake and blur; the faster the shutter speed, the more suitable for capturing instant movements, but the less light would enter), and the sensitivity (when there was enough light, use low sensitivity to get clear image quality; when the light was dark, it could be increased appropriately, but too high would cause noise). Focus must be accurate. You can choose to focus on a single point to ensure that the subject is clear or to shoot moving objects with continuous autofocus. The white balance can be adjusted according to the lighting environment, such as daylight, cloudy, tungsten light, etc. Or you can customize the white balance to get accurate color. The built-in flash had a limited effect of replenishing light, while the external flash was more powerful and flexible, and the angle and intensity could be adjusted. After taking the photos, they should be checked in time to improve the shortcomings. However, with regards to the DSLR scanner, if it was referring to the scanner used to scan the film, it was necessary to ensure that the film was placed correctly, set the scanning parameters according to the scanner's operating instructions, such as the resolution and other parameters, and ensure that the connected computer or equipment worked normally to store the scanned image data. However, since the reference did not mention the use of the DSLR scanner in detail, this part of the information may not be comprehensive enough. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
