Silver salt photography
Silver salt photography was a general term for a type of photography method. Daguerre photography was a type of silver salt photography invented by Daguerre in 1839. It used mercury vapor to develop the exposed silver salt coating. The exposure time was about 30 minutes, which was much shorter than Nieppes's solar-hardened photography method. This method produced fine prints, uniform tones, and was difficult to fade. It was difficult to copy, and the image was reversed from left to right. It was realistic and three-dimensional, but when viewed from different angles, it would turn from a positive image to a negative image. The image formed on the thin silver layer was easily damaged, and the use of mercury vapor to develop could cause mercury poisoning to the photographer. The cost of shooting was high, but it became a mainstream photography method until it was replaced by new techniques such as wet edition guncotton photography in the 1850s. Traditional silver salt photography referred to the use of traditional film cameras, using silver ions as a light-sensitive medium to shoot. After processing, the photos were obtained on light-sensitive photographic paper. The shooting, processing, and imaging processes were all manually completed. There was also the gelatination method (gelatination), which was also a type of silver salt photography. It appeared around 1880 and replaced the previous wet croton photography method.

It was a visual form that served the business.

Personal photography, travel photography
The following are some of the key points related to personal photography: ** 1. Initial preparations ** 1. ** Costume matching ** - They had to choose suitable clothes according to the different scenery. For example, in a small and refreshing scene like the rape field, it was better to wear light-colored, casual clothes. It was more appropriate to avoid red and purple, high-end and stylish clothes, such as white T-shirts and blue denim overalls. At the same time, the matching of clothing should consider the coordination with oneself and the environment, including makeup, styling, and so on. 2. ** Equipment preparation ** - Cameras or mobile phones could be used for travel photography. If you used a camera to take a selfie, you might need to buy an additional remote control. Some cameras could be connected to the phone through Wifi, and you could see yourself in the camera in real time on the phone screen for composition. The phone also had a variety of selfie functions, such as timed shots (the Glory 30S phone's photo page had "2 seconds, 5 seconds, 10 seconds" options), voice-activated photos (useful in quiet environments), and smiley face shots (better lighting, more practical within 5 meters). ** 2. Techniques and taboos during filming ** 1. ** In terms of composition ** - To avoid taking pictures from the hands, feet, and joints of the subject. When setting up a selfie, set up the tripod, put the camera or phone on, and adjust the camera position and composition. For example, when you want to be a part of the scenery or take a photo at a scenic spot, you can set a delayed selfie or even continuous shooting to adjust the ideal composition. - Pay attention to the position of the character in the picture, avoid being rigidly in the middle of the picture, and make the character and the background form an organic whole. - If there are horizontal lines (such as the sea, the lake) or the horizon (such as a sea of flowers), avoid these lines crossing the main parts of the character (such as the head and neck). If it is unavoidable, try to move the horizontal line below the shoulders of the character. 2. ** Selection of background ** - When taking portraits, the background should be carefully selected and the scenery with local characteristics should be used as the background, but the background should be avoided. If too many elements entered the picture, it would make people dazzled and lack highlights. The background color had to be unified so that it could better highlight the characters. 3. ** Face and posture ** - If his expression and posture were not good, he could take more photos to solve it and increase the probability of taking a satisfactory photo. 4. ** To prevent the host from being overshadowed by the host ** - The accompanying objects in the scene (such as green plants, utility poles, etc.) could not be more eye-catching than the characters. Generally, the accompanying objects should not be larger than the main body, and the colors should not be brighter than the main body. Otherwise, it would distract the audience's attention on the characters. ** 3. Shooting Techniques (Shot Manipulation, etc.)** 1. ** Video Shooting (if involved)** - He could use a low-angle mirror lift (push forward), surround (take a picture of the scenery), and lower (finish). - There was also tension composition, upside-down horizontal shooting, graphic composition, telephoto shooting, leaf gap, backlighting shooting, ant perspective, leaf reflection, lock focus first, surround shooting, looking for light and shadow, side framing, road extension, overall finishing, and other techniques to create a cinematic feel. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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.
