Common colors such as neon yellow, neon orange, and neon green were more common in reflective vests and had better reflective effects. The fluorescent color could provide a good visual effect in a dark environment, allowing the user to have a good safety warning in case of bad weather or poor lighting, reminding the driver or other personnel to avoid accidents. However, in forests or areas with greenery, neon green may not be the best choice because it may mix with the background color and reduce visibility. In this case, neon yellow or orange may be better. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reflective paint was a kind of paint with special reflective properties. It was made of an acryl resin as a base material and a certain proportion of directional reflective material mixed in a solution. The reflective principle was to reflect the light back into the human line of sight through reflective beads, thus forming a reflective effect. This effect was more obvious at night. In terms of road signs, there were hot-melt reflective road marking paint and room temperature solvent-based road marking paint. The hot-melt road reflective marking paint was synthesized with high-quality foreign chemical materials. After being heated into a molten state, it could form a thick film at a suitable temperature. It had the characteristics of bright color, strong identification, significant reflection at night, good construction performance, fast drying, strong cohesion, good wear resistance and durability, and was suitable for changing traffic markings on various roads. The normal temperature (cold) road marking paint is made of resin, color and filling materials, and organic liquids. It has fast drying, medium resistance, and good maneuverability. It is widely used in various pavements and various places. Suburban roads and freeways are more suitable for the use of hot melt road reflective paint. It is a single-component coating composed of acryl resin, color and filling materials, auxiliary agents, and liquids. It has a tough film, strong attachment, excellent wear resistance, good water and alkali-resistant weather resistance, clear film, and no bleeding on the asphalt pavement. In addition, it was also applied to some other products, such as reflective sunglasses with a very thin reflective coating on the lens, which could enhance the resistance to light from above, while allowing more light to enter from below and horizontally. There were also brands such as Huisheng paint, road reflective paint, tunnel highway marking paint, concrete exterior wall road reflective paint, and other reflective paint related products. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

If the problem was related to the Peugeot 301's reflective lens, if the rearview mirror lens was damaged, the rearview mirror assembly could only be replaced. There was no separate lens provided. If it was replaced in the repair shop, the price would be about 180 yuan, using ordinary parts and the quality was average. If it was replaced in the 4S shop, the price would be about 400 yuan, using original parts and the quality was guaranteed. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The 85-inch reflective umbrella might be referring to the 85-centimeter black and silver parabolic umbrella. This kind of umbrella could be used for soft light photography in the studio. It was a kind of photography accessory. The material inside the umbrella had a great impact on the image. The silver umbrella had a higher reflection rate, and the reflected light tended to be parallel, with a stronger directionalness, making the visual experience harder. The white umbrella reflected more diffused light, making the visual experience relatively soft. The size of the umbrella would change the area of the light source. When the light level was constant, the larger the area of the light source, the smaller the contrast. The area of the light source of an open umbrella was relatively larger, and the contrast was smaller. A half-opened umbrella would reduce the area of the light source and increase the contrast. The depth of the umbrella would also affect the softness of the picture. When the distance between the light source and the axis of the umbrella was constant, the angle of light emitted by the previous umbrella was wider, and the light received was relatively uniform. The deeper umbrella had more precise control of the light field, more prominent, and the light decay was obvious. In addition, by adjusting the handle of the umbrella to change the distance between the axis of the umbrella and the light source, it would also produce different effects on the screen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Reflective photography was a special field of photography. Due to the high surface smoothness of reflective and semi-reflective products, most or all of the illumination could be reflected, while at the same time reflecting the surrounding objects. This was both its characteristic and the difficulty of shooting. There were different lighting methods for different shapes of reflective objects: - ** Three-dimensional reflective object **: For stainless steel products, you can use a curtain type soft light distribution, or place a milky white plexiglass arc cover on the still life stage for light distribution, or you can also make a circular soft light cover for circular light distribution. The use of lighting on both sides can produce an obvious three-dimensional effect. If he didn't use white soft paper to surround the surroundings and light it up from the outside, the main body would turn gray, and the surface would be mottled due to the surrounding objects. - ** Flat Reflective Items **: For example, flat metal reflective items such as stainless steel knives and forks, which can use the reflective characteristics of the metal surface to express its texture and shape. When shooting, take a bird 's-eye view, place a high backlight behind the main body, and adjust the main body's position and tilt angle to obtain the ideal reflection effect according to the principle that the angle of incidence is equal to the angle of reflection. According to the needs of the shooting, soft light was used to reduce the reflection, and hard light was used to enhance the reflection. For example, the flat metal wrench with chrome-plated could be used to enhance the reflection with hard light, and many silverware could be used with soft diffused light. When shooting reflective objects, the light quality was soft and uniform, the light source area was large, and indirect illumination was the key. An isolation cover (such as white fiber cloth or translucent tracing paper to surround the goods, and then evenly distribute the light from the outside to the inside of the cover) could be used to control the light. By adjusting the light intensity outside the isolation cover to control the contrast of the appearance of the goods, the isolation cover could become a large area uniform light source, the light quality was soft, and the messy light and shadow and flares were avoided. In addition, there are some auxiliary tools that can be used when shooting reflective products: - ** Reflective Plate **: Different surfaces have different reflective effects. For example, the silver surface has a strong reflective effect, which is suitable for filling in shadows when the sun is strong; the golden surface has a high reflective rate and a warm color, which is suitable for taking photos of the character's warm skin; the white surface has a weak reflective effect but is gentle, which is good for showing the details of the skin; the black surface is a light absorbing plate, which can be used to increase the three-dimensional effect; the soft light screen can filter the light when the light is hard to make the skin delicate. - ** Polarizing lens **: composed of two lenses, inner and outer. Rotating at a certain angle can eliminate the reflection of non-metallic objects to a certain extent, but there are certain limitations (such as the angle between the shooting direction and the reflective surface is not suitable, shooting through double-layer glass, cloudy or sunny backlighting, the blue effect of the wide-angle lens is unnatural, and the effect of eliminating the reflection of water is not good when the water is not clear, etc.). When lighting, you can also use light and shadow to form. Not all metal objects need to use soft light or curtain lighting. The combination of the projection produced by hard light and the bright reflection of the object can add interest to the picture. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
