Photographic background visualization
Photographic background visualization was a kind of photographic effect. It was designed to blur the background in the photo and highlight the subject. The following are some common methods to visualize the background of a photo: ** 1. Equipment factor ** 1. ** Large aperture lens ** - For traditional cameras (such as single-lens reflex cameras, microcameras, etc.), using a large aperture lens (such as an aperture value of f/1.4, f/1.8, etc.) could effectively blur the background. A large aperture could reduce the depth of field, causing the background to be outside of the depth of field and thus become blurry. This was because the large aperture allowed more light to enter the camera, while also reducing the range of clear images. 2. ** Telephoto lens ** - Telephoto lenses (such as lenses above 200mm) also helped to achieve background blurring. The telephoto lens would compress the space, making the background look closer to the subject. Due to its own optical properties, the depth of field was shallow, making it easy to blur the background. ** 2. Software processing ** 1. ** Mobile APP** - When there was no professional equipment, he could use the mobile APP to achieve background visualization. However, it was not easy to find an app that could achieve a good background visualization effect among the many apps on the market. Although some apps claimed that they could blur the background, the actual effect might not be satisfactory. 2. **Photoshop (computer software)** - If you are familiar with the Photoshop software, you can use its various tools to achieve background blurring. For example, one could use tools such as the "Gaussian Blur" filter to blur the background layer and then adjust the degree of fusion between the main body and the background to achieve the effect of background visualization. However, this required certain operational skills and software usage knowledge. Read more exciting novels for free
Photographic background cloth installation
If you want to install the studio background cloth, you need to prepare the background cloth holder first (a set of two). Open the lowest support leg and tighten the fixing screw, then try your best to push it out with your hands until it can't be opened. Next, adjust the height of the support. You can use the tightness of the fixing screw and stretch the steel support by hand. After the two supports were assembled, the background cloth was wrapped around the pipe (the tightness of the wrapping was suitable for adjusting the height in the later stage). The pre-assembled rotating plastic cover was inserted into both ends of the tube, and one end of the tube was lifted to clip the buckle into the groove of the support (there were two grooves, which could be used to place two pieces of background cloth). Both ends of the tube had to be stuck in the card groove. Finally, the axis of the yellow roller could be adjusted up and down according to the shooting requirements. If you want to hang the background cloth on the wall, one method is to use universal glue. First, put the universal glue in the glue gun, apply it around the background cloth, and then press it on the wall to fix it. The other method is to find a rope to sew in the background cloth, nail the pushpins in the installation area, and then hang the background cloth. If you want to install a remote-controlled shaft lift (fixed on the wall), you can first find cardboard and make a template according to the opening position of the box on both sides. Use the template to make a mark for the expansion screw at the designated position on the roof (measure the distance between the left and right sides, and determine it according to the length of the shaft). Then use the impact drill to make eight holes and knock in the expansion screw. If the right motor shaft is very heavy, you can use the triangular lifting support rod to lift the right box, free one hand to screw, first install the two diagonal expansion screws on the box, then tighten the other screws after the box is fixed, and finally insert the eight rollers. <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 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>
