Sharpness in photography
Sharpness in photography was a physical measurement used to measure the quality of the edge of a picture. It could also be called "definition." The quality of the edge was related to the definition perceived by the human eye. It was an indicator of the clarity of the image plane and the sharpness of the edge of the image. From the perspective of imaging, sharpness described the speed at which the image information at the border transitioned. The transition speed of high contrast was fast and could form a clear edge, while the transition buffer existed in low contrast, and the image edge was blurred. The sharpness could be judged by the clarity of the edges and details of the objects in the picture. The higher the sharpness, the clearer the details of the picture. On the contrary, the picture was blurry, the details were not expressed enough, and the edges were not coordinated with the picture. Sharpness was related to contrast. The higher the sharpness, the higher the edge contrast. Increasing the edge contrast would also increase the sharpness. The "sharpening" function in the image processing software used this principle. In photography, different scenes had different requirements for sharpness. When shooting a landscape, one often pursued sharpness to obtain a sense of déjà vu. However, when shooting a portrait, too high sharpness would cause particles to appear on the skin of the character, magnify small skin flaws, and even cause white edges to appear on the edges of the face, hairline, eyebrows, eye sockets, nose, lips, and other black and shadow parts, affecting the image effect. In addition, there were other factors that would affect the sharpness of the photo. In terms of lenses, the sharpness of a fixed-focus lens was generally higher than that of a zoom lens. Because of the large number of lenses in a zoom lens, it was more difficult to design, and it was easy to produce optical aberrations. Moreover, the large number of lenses would reduce the contrast and increase the facula. The fixed-focus lens usually had a larger aperture than the zoom lens. Under the same circumstances, the sharpness of a large-aperture lens was higher than that of a small-aperture lens. In terms of shooting operations, use a high-speed shutter when shooting with a hand-held camera, stabilize the camera to reduce shaking, use a low sensitivity to reduce noise, and focus correctly to make the subject clear.(Automatic focus is convenient and practical, and manual focus can achieve better control when shooting speed is not required), adjusting the photo style to increase the sharpness (can be directly set in the camera photo style), using a wide-angle lens to shoot scenery (large depth of field, large front and back clear range), long-distance shooting (the clear range of the focus can cover the background to make the picture clearer), etc. all help to improve the sharpness of the photo.

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.

The role of camera sharpness
The sharpness of a camera could be intuitively understood as the clarity of the image. It was an indicator that reflected the clarity of the image plane and the sharpness of the edge of the image. From the perspective of the imaging effect, the higher the sharpness, the clearer the details of the picture. On the image plane, the contrast of the details was higher, such as the wrinkles and spots on the face were clearer, and the ups and downs of the facial muscles could be more vivid. In the vertical direction, where the dark or black lines and the black-and-white image changed, the edges were sharper, and the overall picture was clearer. In landscape photography, a high degree of sharpness could make the picture look like a large scene. At the same time, sharpness was related to the edge contrast. The higher the sharpness, the higher the edge contrast. Increasing the edge contrast would also increase the sharpness. The " sharpening " function in the image processing software was based on this principle. However, not all photography works needed high sharpness. For example, in portrait photography, too high sharpness would magnify the small flaws on the skin of the character, resulting in graininess. It might also cause white edges to appear on the edges of black and shadow parts such as hairline, eyebrows, eye sockets, nose, lips, etc., affecting the image effect.

How to adjust the sharpness of photography
The method to adjust the sharpness of the camera was as follows: 1. ** Find the sharpness setting menu **: For different camera brands and models, the sharpness setting in the menu may be called "sharpness" or "contrast". You need to find the corresponding setting option in the camera menu. 2. ** default setting **: The default sharpness setting of most cameras is moderate. You can try the default value when you first come into contact with the sharpness setting. 3. ** Adjusts according to the shooting scene ** - ** Portrait photography **: Usually requires high sharpness to highlight the contours and details of the face. - [Landscape photography: Generally use moderate sharpness to maintain the softness of the natural scenery.] - ** product photography **: In order to show the details of the product, a high degree of sharpness is usually required. 4. ** Phased adjustment ** - ** Low Sharpness **: It is suitable for photos that require a soft effect, such as certain artistic styles of photography. - ** Medium Sharpness **: It is suitable for most scenes and can maintain the natural clarity of the image. - ** High Sharpness **: It is suitable for scenes that emphasize details, but over-sharpening may cause noise and artifacts in the image. 5. ** Consider the relationship between sharpness and contrast **: When adjusting sharpness, a higher contrast can enhance the sharpness effect, but excessive contrast may cause image distortion. 6. ** Post-processing **: The sharpness set by the camera is only the foundation. After shooting, you can use post-processing software such as Adobe lighthouse or Photoshop to further adjust the sharpness without affecting the original image data. 7. ** Real-life test **: Take test photos regularly and compare the effects of different sharpness settings to find the sharpness setting that suits your shooting style. In addition, in the photo style of the camera, you can also adjust the sharpness. If you want to take a photo with higher sharpness, you can increase the sharpness to 1 to 3.
