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

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.

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 glass with a white background
There were many factors that needed to be taken into account when taking a picture with a white background. In terms of light distribution, if a glass cup was shot with a white background (such as a Nikon D810 stand-alone camera, aperture f/16.0, exposure time 1/8, an IS of 100, focal length 105.0, etc.), this was an example. The principle of light distribution for white background maps could usually be used in a layer-by-layer manner. Shooting glass white background maps could also be used as a reference. First, set the background light and brighten the white background. However, it should be noted that when the subject is exposed normally, the background may not be exposed enough and turn gray. If you want to achieve a pure white background with an RGH value of 255 as required by Taobao, you may need to completely overexpose the background. Then use the main light to light up the object, which can be placed in front of the left or right of the object.

When shooting glass, there might be a problem with reflection, which could be solved by self-made artifacts. Use a tight dark-colored stocking (black or navy blue, non-flesh-colored transparent), implant the ring inside the stocking, fix it with a long tail clip, cut off the middle circle to form a trumpet shape, and fix the tight end of the stocking on the lens. It can be fixed on the glass, and the lens shoots inside. The camera aperture should be adjusted to blur the dirty things on the glass. Also, pay attention to using clean socks. This method can be used with cameras and mobile phones. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
