photographic sharpness
Acuteness was a physical measurement used to measure the quality of the edge of a picture. The quality of the edge was related to the definition perceived by the human eye. It could also be simply understood as the clarity of the picture. The sharpness of the image could be judged from the clarity of the edges and details of the object in the image. The higher the sharpness, the clearer the details of the image. On the contrary, the image was blurry and the details were not well expressed, and the edges were not coordinated with the entire image. In photography, sharpness had the following characteristics and effects: 1. ** Relationship with contrast **: The higher the sharpness, the higher the contrast of the edge; increasing the contrast of the edge, the sharpness will also increase. 2. ** Effects on different subjects ** - [Portrait photography: Sharpness is not always better.] If the sharpness was too high, the character's skin would have a grainy feel, like a full face full of potholes. It might also cause the edges of the face, hairline, eyebrows, eye sockets, nose, lips, and other black and shadow parts to have white edges, affecting the image. - ** Landscape photography **: Most of the time, they pursue sharpness. High sharpness can make the picture instantly look like a big picture. The factors that affected the sharpness of a photo were as follows: 1. ** The camera factor ** - ** Fixed focus and zoom **: The sharpness of a fixed focus lens is generally higher than that of a zoom lens. Because the number of lenses in a zoom lens was more than that of a fixed-focus lens, it was more difficult to design, and it was easy to produce optical aberrations. The number of lenses would also reduce contrast and increase facula, and the fixed-focus lens usually had a larger aperture than the zoom lens. 2. ** Shooting conditions ** - ** Shutter Speed **: Use a high-speed shutter as much as possible to ensure the sharpness of the photo. When shooting with a hand-held camera, inexperienced photographers would have a higher probability of shooting a fake photo if the shutter speed was set below 1/30s. For telephoto lenses, it is recommended to control the shutter speed beyond (1/focal length). In order to ensure the brightness of the photo, it may be necessary to open a large aperture and lose the "large depth of field" when increasing the shutter speed. It can also be balanced by increasing the USB value. - Aperture: Any lens has imaging errors. Using the largest aperture will expose the lens 'aberrations to the greatest extent, resulting in a decrease in image clarity. Using the smallest aperture will cause light refraction, resulting in a decrease in image clarity. There is an optimal aperture that can improve the image quality. - ** Focus **: Most cameras have an autofocus function, but when the depth of field is particularly small (such as focusing at a close distance to the subject, using a long focal length lens, or using a large aperture to shoot a close-up), the autofocus may not be accurate. You can use manual focus and press the shutter halfway to test whether it is in focus. - ** Depth-of-field **: Depth-of-field depends on the purpose of shooting. Scenery shooting requires a large depth of field, which can be shot with a small aperture, a short focal length lens, and long-distance focusing. Close-up shooting requires a small depth of field, which can be shot with a large aperture, a long focal length lens, and close-distance focusing.

Decrypting the Photographic Eye
Photographic Eye was a special ability that a photographer possessed in photography. From an observation point of view, the camera could find beauty in ordinary things. This required the photographer to have a rich life experience and social experience, as well as a deep cultural and artistic cultivation and foundation as support. Just as Rodin said, a master could use his own eyes to find beauty in common things. In terms of artistic sensitivity: - Be sensitive to lines because the world is made up of lines. Lines like spirals, rhythms, and S-shapes are all beautiful lines worthy of attention. - Be sensitive to light, including the nature of light (hard light, soft light, scattered light, etc.) and direction (forward light, light measurement, side light, etc.). - Color was a modeling method that could enrich the expressiveness and appeal of a photographic work. It could express the photographer's thoughts, exaggerate the atmosphere, and artistic conception. It was necessary to be sensitive to the three elements of color, lightness, and saturation, as well as the three primary colors and light color. - One must be good at observing the geometric figures and beautiful patterns in nature and discover their beauty for creation. - In photography creation, one must gain insight into the beauty of photography elements such as rhythm, melody, shape, tone, color elements, symbols, etc., and apply them to photography works. From the perspective of knowledge and thinking: It is recommended to study literature (the meaning of poetry and songs), music (rhythm and melody), China painting (the artistic conception of ink painting), photography aesthetics and color science (the laws and concepts of beauty), photography philosophy and philosophical thinking. From a practical point of view, photography was a very practical subject. One needed to take more photos, practice more, and summarize more. Through shooting practice, one would constantly improve their photography skills. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photographic scene composition
Here are some common ways to compose a photo scene: - ** Nine-palace grid composition (tic-a-square composition)**: Place the main part of the picture at four points where the horizontal and vertical lines meet. It is suitable for shooting people, animals, flowers, plants, buildings, etc. It can make the overall visual effect of the picture better and more ornamental. - ** Three-point composition method **: Divide the picture into three equal parts and place the scenery in one-third or two-thirds. It was widely used in scenes with a wide field of vision, such as the horizon and sea level. Since the three-point line was close to the golden section line, the picture shot according to this composition was neat and visually comfortable. - ** Symsymmetrical composition **: suitable for shooting scenes such as regular buildings and reflections on water. If there was no reflection on the water surface when shooting, one could pour water on the ground and shoot close to the water surface to create a symmetrical effect. - [Framed composition method: Use objects around you, such as branches and the edges of buildings, to form a natural frame to wrap the scenery you want to present, so that the audience can focus more on the scenery within the frame.] - Guiding Line composition: Find lines in the picture, such as stone blocks, utility poles, roadside, walls, etc., to guide the audience's attention to the designed scenery or the main body of the picture. - Diagonal composition: Makes the picture more vivid, shocking, and ornamental. It is often used to take portraits, still life close-ups, pets, and children's photos. - Close-up composition (partial composition): Sometimes, the part is bigger than the whole. For example, taking only half of the picture for a close-up of a person may make the photo more advanced. When filming a dancing person, the visual focus would be on the reflection, lines, and motion. It was more eye-catching than directly filming the person. - [White space composition: Allow the character to occupy a small portion of the picture, leaving a large area of blank space to highlight the character.] - ** Foreground composition **: Add objects such as flowers and leaves between the character and the camera as the front. Blurring the front props can make the character more prominent. - ** Triangle composition **: When taking a portrait, use your limbs and body to form a triangle, such as sitting, squatting, bending over, etc., to make the photo relaxed and natural. - ** Center composition (center composition)**: Place the main body in the center of the picture, making the character stand out in the middle of the picture and attract the focus. It can create a beautiful artistic conception when it is suitable for a relatively open scene, and the back view can also be more imaginative. It can also place the facial features of the character at the intersection of the golden ratio of the picture, so that the audience's attention can be focused there. - [Three-point Method Combined with Guiding Lines]: Using the dividing lines in the environment, a variety of composition methods can be superimposed. - ** Foreground composition + Method of Three-thirds **: For example, the rape flower is used as the composition of the rich foreground picture, and the color contrast is used to enhance the visual effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Downhole photographic instrument
The following information was related to the underground photography instrument: - The underground camera/video recording equipment has the requirements of clear imaging in low illumination, which can maintain the clarity and color of the image under low illumination. It has the function of strong light suppression, which can avoid the strong light caused by the miners 'headlights and environmental lighting, and can be turned on simultaneously under the condition of sufficient environmental lighting. It needs better sealing. For example, the special camera in the underground will be equipped with two chambers to solve the problem of poor sealing. If the sealing is not good, it will cause fog inside the camera and cause the image to be blurred. There are lightweight requirements. Due to the limited underground transportation equipment and installation conditions, the equipment should be as light as possible for transportation and installation; There should be wireless communication requirements, supporting Wifi and 5G communication modes; Dust prevention requirements should be met. Due to the large dust in the underground coal mining face, heading face, belt tunnel transportation and other scenes, the equipment should support self-cleaning; There should be anti-vibration and anti-shake requirements. When installed on equipment such as hydraulic support and tunneler, it can support anti-vibration and anti-shake to ensure stable imaging of video images; It should also have AI analysis requirements, that is, it has AI functions, and can directly load intelligent analysis algorithms to achieve local analysis. - The mine intrinsic safety infrared night vision device was a device that could be used underground. It had the function of remote detection in low light or darkness. The device had the function of taking pictures and recording videos. Underground shooting used electronic sensors to convert optical images into electronic data and store them in digital memory cards. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Principle of Photographic 3D Scanning
The principle of a photo-type 3D scanner was similar to a camera taking photos. It used the internationally advanced structured light non-contact photographic measurement principle, which was a composite three-dimensional non-contact measurement technology that combined structured light technology, phase measurement technology, and computer vision technology. When in operation, the grating projection device projects a few pieces of specially programmed structured light onto the object to be measured, and the two cameras forming a certain included angle collect the corresponding images simultaneously, then decode and calculate the phase of the images, and use the matching technology and the triangle measurement principle to calculate the three-dimensional coordinates of the two cameras in the common visual area, so as to obtain the three-dimensional spatial information of the object surface, and finally obtain the point cloud data of the object surface to be measured. Different types such as photo-type blue light 3D scanner were based on this principle. In practical applications, the measurement range could be freely adjusted according to needs, from small parts scanning to the overall measurement of the body. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
