Original camera rear lens flash
The original camera's rear lens flash had a variety of application techniques when taking photos and videos: - ** Flash sync detection (for cameras)**: If it is a domestic camera, sync can be performed at a speed of less than 1/60 seconds. During the test, open the back cover of the camera without loading the film, adjust the aperture to the maximum, and aim the flash at the lens. If the flash is connected to the camera, put a mirror 40 cm in front of the camera lens, then press the shutter to make the flash shine. The eyes look forward through the lens. If you see a dazzling circular spot, it means that the flash is synchronized and can be used normally; otherwise, it is not synchronized and needs to be repaired. - ** Photographic Skills ** - ** Use the environment **: If there is a street light in the shooting environment, ask your friend to adjust the exposure to the lowest level first, then turn on the contrast filter. This can solve the problem of 80% of the scattered powder reflection in the night photo. At night, the camera would take a top-down view. If the head was slightly raised, the flash would lengthen the length of the neck, making the head and face look small. They could also create a difference in height for filming. - ** With the help of props and post-processing **: The background can be the white wall at home. After using the phone's rear camera to turn on the flash, adjust it with the wake-up picture. Choose Film- Mini90 as the filter, click Advanced Editor, adjust the clarity to 60, click Special Effects, choose Basic-Over-exposure, click Advanced Editor-adjust parameters, noise 40, size 72, intensity 37, filter 24. - ** Character preparation and auxiliary tools **: When taking photos with the rear camera, you can tie your hair appropriately, wear pink or blue clothes, and prepare dried flowers or roses as decorations. As the composition of the rear camera may be biased, a small mirror can be prepared to observe expressions and movements. When shooting in dim light, turn on a small lamp to make your skin look good. If you use a light camera, you can choose a mist filter plus a pink filter, find a clean wall or curtain as a monotonous background, put your phone on a tripod or ask a friend to help you shoot. - ** Video Shooting Techniques **: Turn on a mode with better image quality such as 1080p, turn on beauty and adjust the parameters, such as skin leveling 30, whiteness 24, clarity 50, big eyes 15, adjust the nose shrinking value according to your own situation (such as 30), add a blush to the makeup, switch to the rear, turn on the flash and start shooting. After shooting, you can directly save and repair the image quality to obtain the same creamy texture as the blogger. You can also tailor it according to the video. If you want a sweet girl's video, you can set up a small warm light behind you. Read more exciting novels for free
The camera lens is expensive
In the field of photography, expensive lenses had their value. Generally speaking, more expensive lenses had higher performance in terms of optical quality, workmanship, and performance. For example, in the field of medium and long focal length lenses, Canon's RF70 - 200mm f/2.8L IS USM was priced at 16999 yuan, and the Sony70 - 200mm F2.8GM OSS II was priced at 18999 yuan. These lenses were expensive, but they could provide better imaging results, excellent focusing performance, and good durability on their respective cameras. However, with the changes in the photography market, the relationship between price and value did not completely follow the traditional principle of "you get what you pay". In the micro-monocle era, although some high-end lenses had improvements such as quieter focusing, better design, and improved electronic functions, compared to similar lenses in the DSLR era, users felt less about the improvement in optical quality, but the price generally rose. Some of the affordable entry-level lenses, such as the 50mm f1.8 lens, were no longer as affordable as before. Branded lenses of this size were even hyped up to three times the release price. 24 - 105mm f4 or similar lenses were nearly twice as expensive in the micro-single era as in the single-lens reflex era. Although the optical quality had improved, there was no particularly huge breakthrough. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Single-lens reflex camera with glasses
If you wore glasses and used a single-lens reflex camera to shoot, most single-lens reflex cameras had a refraction adjustment function. You can aim your eyes at the viewfinder, and after automatically focusing on an object, adjust the refraction adjustment button to the left or right until you see the clearest image. However, the position of the refraction adjustment button might be different for different brands of DSLR. It was usually next to the viewfinder. In addition, there were also photographers who said that they could see the viewfinder clearly with a single-lens reflex camera. If you feel that the image you see through the viewfinder is blurry, you can also consider putting on your glasses and shooting directly. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is there a difference in the size of the surveillance camera lens
There was a difference in the size of the surveillance cameras. Different sized lenses had different viewing angles and distances. Generally speaking, the smaller the millimeter of the lens, the larger the angle of the surveillance picture, but the clearer the distance. On the contrary, the larger the millimeter of the lens, the smaller the angle of the surveillance picture, and the clearer the distance. For example, the 2.8mm focal length lens has a large viewing angle, suitable for monitoring small spaces such as storage rooms within 3 meters; 4mm can be used for indoor environments such as living rooms and small shops; 6mm is suitable for small shops or doorways of 5 - 10m; 8mm is best for outdoor roads and alleys of 10 - 20m; 12mm is mainly used for specific locations such as entrances and exits of about 20 - 30m. In addition, from the relationship between angle and distance, the larger the angle, the closer the distance. For example, the 3.6mm lens was 67.4 degrees, and the distance was 15 meters; the 6mm lens was 42.3 degrees, and the distance was 20 meters; the 8mm lens was 32.6 degrees, and the distance was 25 meters; the 12mm lens was 22.1 degrees, and the distance was 40 meters; and the 16mm lens was 17.1 degrees, and the distance was 60 meters. The common surveillance camera lenses on the market were arranged according to the size of the frame: 2.8mm, 3.6mm, 4mm, 6mm, 8mm, 12mm, 16mm, 24mm, etc. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
