This kind of light-sensitive glass plate was the light-sensitive material for wet photography. Read more exciting novels for free
photographic plate process
The dry-plate method was a stage in the development of photography. In 1868, W.H. Harrison proposed the idea of using cotton-padded gelatins to replace cotton-padded creams. In September 1871, Maddox of the United Kingdom introduced his research results in the British Photograph magazine: Silver Bromid Cream, which was made of glue-like gelatins, was applied to glass while it was hot. When it dried, it would not crystalize like cellophane. When others were experimenting with Maddox's method, they found that the longer the heating time during the preparation of the cream, the greater the sensitivity of the cream. The dry-plate method was developed in the context of people's desire for a "dry" coating material that could be bought in stores and loaded into a camera at any time. It was an important achievement in the development of photography technology. Previously, photography methods included the silver plate method and the wet plate method (including the results of the Amber plate photo, tin plate photo, etc.). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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.

Photographic equipment
Burning equipment was a common phenomenon among photography enthusiasts. In terms of equipment types, photographic equipment included cameras, lenses, and related accessories. For example, in terms of cameras, there was a huge difference in price and performance from entry-level to high-end models. For example, the first generation of the SonyA7C may feel that their equipment is lagging behind when the new model is launched soon after they get it. There were also many choices for lenses. The prices of lenses with different focal lengths and apertures were significantly different. Some lenses, such as the Canon's 50mm f1.8 " small spittoon " version of the radio frequency lens, had skyrocketed in price. The second-hand price was even close to double the normal price of a new lens. The price of a new lens on sale was even more outrageous. Despite its ordinary design, cheap materials, and conventional specifications, the price still soared. In the field of drone photography, this situation also existed in different models of Djiang. For example, the D.J. mini2, mini3Pro, Royal 3, etc. Every upgrade attracted photography enthusiasts to change their equipment in pursuit of better shooting effects. For example, the mini3Pro was larger than the mini2, with a larger LCD, a non-destructive vertical camera, and a small white camera. However, there were also problems such as lens fog, while the Royal 3 might attract enthusiasts to upgrade because of better shooting effects. However, this series of equipment updates meant continuous investment in funds. Some portable cameras, such as the Fuji X100 series, had average performance. They didn't have super image quality, a powerful focusing system, and negligible anti-shake, but their prices rose from a few thousand yuan to more than ten thousand yuan. Ricoh's GH series, although it had the advantage of being portable and targeted for street photography, its image quality, focus, and battery life were ordinary. The new model didn't upgrade its highlight technology. It added a filter and sold it as a new model. Soon after it went on the market, the price rose by one or two thousand yuan. There was also the SonyRX100M7 card camera, which cost more than 10,000 yuan. This showed that in the field of photographic equipment, price and performance did not always match, but there were still many photographers who were willing to invest money, thus showing the phenomenon of " burning equipment." <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Photographic gold
The prime time for photography was usually the first hour after sunrise and the last hour before sunset. At this time, the light was rich in color, the angle was low, and the atmosphere was better. The light was softer and there were no glaring shadows. Overall, it looked very warm and likable. However, it was important to note that primetime was not suitable for all types of photography. For example, street photographers preferred contrasting images and would shoot at noon, while some macro photographers preferred to shoot on cloudy days in order to capture color saturation and rich details. In addition, according to the degree of cloud cover in the sky, the golden time might change or even not appear. Near the equator, the golden time usually lasted for one to two hours, and the interval between winter and summer did not change much, but if it was near the North Pole or the South Pole, the golden time would be very different and last longer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
