Glass reflection photographyIn photography, glass reflection was a common problem, but it could also be skillfully used or effectively solved.
** 1. Use of glass reflection **
1. ** Increases the layering and surrealism of the image **
- The proper use of the mirror reflection of glass in a real-life scene could increase the layering of the picture and even create a surreal work. For example, to guide the audience's line of sight, they could use the window to cover half of the model's face, so that the image could focus on the model's eyes, so that the smile could be vaguely seen in the reflection. They could also enhance the emotional expression, so that the back and face of the protagonist could appear in the image at the same time, doubling the same emotion and strengthening the emotion of the image. Or they could create an abstract atmosphere, so that the reflection could be deconstructed and reorganized into a new image.
2. ** Create special effects **
- The reflection of the glass could have a "second exposure" effect. By adjusting the distance of the subject, the overlapping effect of the image could be maximized, thereby increasing the information content of the image. He could also use a small mirror (or a smooth surface of a mobile phone) as a reflective board to create a superimposed image effect and enhance the atmosphere of the environment. Moreover, the inverted words reflected by the glass sometimes had a specific aesthetic value.
** 2. Solution to the reflection of glass **
1. ** Adjusting shooting angle and lighting **
- When taking photos, you have to look for more angles and pay attention to the light. If it was indoor shooting, the indoor lights could be dimmed; if it was outdoor shooting, a microscope could be used (but the microscope had limitations, such as the angle between the shooting direction and the reflective surface was not suitable, and the effect was not good when shooting through double-layered glass.).
2. ** Choose the appropriate shooting mode and tools **
- When taking photos, choose manual focus mode to focus more accurately on the subject.
- Self-made artifact to solve the reflection problem, such as using a black stocking (Tight, rootless, dark stockings, black or navy blue), a ring for a ring and a long tail clip to make a tool, implant the ring into the stocking, fix it with a long tail clip, cut off the middle circle to form a trumpet shape, put the tight end on the lens, and the other end can be fixed to the glass.(If the lens is small, the loose socks can be tied with a pressure band.) This method is low-cost and light. It can be used on cameras and mobile phones, but when using it, the aperture must be adjusted to blur the dirty things on the glass and the stockings must be clean.
- For the Huawei P40 series phones, you can use its "AI Reflection Elimination" function to take a photo first, then click on the photo in the gallery to enter the smart editing interface, click "Editor-Smart- AI Reflection Elimination", and finally save the changes. This function also supports editing all the pictures in the gallery.
- You can also use the professional extinction cover of the high-quality camera or the anti-reflective artifact specially developed for mobile photography (there are two models of mobile phone extinction cover, which are suitable for different camera distribution models. They are made of silica gel, soft and not harmful to the machine and have good malleability). When shooting, stick close to the glass and eliminate the reflection by physical means. When shooting indoor city night scenes, aquariums, zoos, and vehicles, you can shoot the ideal picture without professional equipment.

Break the glass and write reflection" Reflection on Breaking Glass "
In life, breaking glass, whether intentional or unintentional, had brought about many negative effects and was worth reflecting on.
From the perspective of damaged property, glass, as an item, whether it was in the family, in the school, or in other public places, had a certain value. Breaking it meant that the item was damaged. This was a sign of a lack of respect and treasure for the item. For example, in school, the glass in the classroom was designed to create a good learning environment for students. If it was broken, it would destroy the overall layout of the environment and affect the normal use of the classroom.
From a safety perspective, the glass would produce sharp fragments after breaking, and these fragments were likely to cause harm to the people around them. Just like in a family scene, if a child breaks a glass while playing, not only may the child be scratched, but the parents may also be injured in subsequent cleaning or accidental contact, which undoubtedly brings a safety hazard to the family.
In terms of social impact, if the glass was broken in a public place, it might also scare others and affect the normal order of the surrounding people. Moreover, this kind of behavior might set a bad example for people, especially teenagers, and it would easily lead to imitation behavior.
If it was because of his own subjective impulse to break the glass, it reflected his lack of emotional management and behavior control. For example, breaking a glass in a moment of anger or bravado was very irrational. And if it was accidentally broken, it also meant that the behavior was not cautious enough and did not fully consider the surrounding environment and possible consequences.
In order to prevent such behavior from happening again, I need to improve my ability to manage my emotions in the future. I need to stay calm when I encounter things and not act impulsively. At the same time, be it when playing or doing other activities, they had to be more careful and pay attention to the surrounding environment, especially where there were fragile items. They should also strengthen their awareness of the protection of property, respect and care for public and private property.

Principle of glass reflection filmThe reflective film was an intelligent spectral-selective heat-insulation film that relied on reflection to achieve the purpose of heat insulation. It uses a magnetic-control spraying process to evenly spray precious metals such as gold, silver, titanium, nickel-and-aluminum onto an optical-grade PET base material to form a multi-layer high-heat-insulation metal film layer, which has a long-lasting reflective and heat-insulation effect on the infrared heat in the solar spectrum. The transparent pet film was sprayed with multiple layers of precious metals to form a highly heat-resistant metal film to reflect infrared heat, thereby achieving the purpose of heat insulation.

What are the effects of glass on sound reflection?The effect of glass on sound reflection was mainly related to the following factors:
1. ** The smoothness of the glass **: The smoother the glass surface, the stronger the reflected sound, especially the high-frequency sound. For example, the double-layered soundproof glass had a smooth surface. Although the soundproof effect was good, it had almost no sound absorption effect and had a strong reflective ability.
2. ** Glass thickness **: Glass of different thickness will reflect different frequencies of sound differently. For example, 4mm thick glass is almost transparent to sound in the high frequency range of 3500 Hertz (weak reflection); 6mm thick glass has poor sound insulation for frequencies around 2000 Hertz (meaning strong reflection); 10mm thick glass does not perform well at 1300 Hertz (strong reflection); 25mm thick glass has no obvious weakness.
3. ** Glass structure type **:
- ** Lined glass and single-piece glass **: Lined glass can reduce the transmission of sound more than single-piece glass of the same quality, which means that the single-piece glass may have a stronger reflection of sound than the glued glass. For example, 2+ 2mm glass was more resistant to high-frequency sound than 4mm glass (it could reduce an additional 8 to 10 decibels), indicating that 4mm glass was more reflective of high-frequency sound.
- ** Hollow glass **: Increasing the thickness of the hollow layer in a small range has no significant effect on sound insulation (reflection is also a part of sound insulation). For example, if the hollow glass with a hollow layer thickness of 10mm is compared with the hollow glass with a hollow layer thickness of 20mm, there is basically no difference in sound insulation performance, that is, the reflective ability is not much different. Moreover, the performance of the hollow glass in the low frequency band may be poor (the reflective ability may be strong). For example, the sound insulation effect of the 6+ 12A +6mm hollow glass is generally better than that of the 6mm single-piece glass, but the difference is only 2 or 3dBm, and the performance of the hollow glass in the low frequency band may be poor (the reflective ability may be strong).

The camera at night can eliminate the reflection of the window glassThe following methods can be used to eliminate the reflection of the window glass in the night scene of the camera:
1. " Adjusting the camera angle: Make the camera angle form a certain inclination with the window glass to prevent the lens from facing the reflected light source on the glass surface.
2. Sticking anti-reflective film: Sticking a special anti-reflective or low-reflective film on the window to reduce the probability of light directly reflecting back to the camera.
3. Control the indoor light source: adjust the indoor lighting equipment to reduce unnecessary internal light sources at night, or adjust the direction of the light source to avoid direct light from the window.
4. Use a Polarizing filter: For cameras with changeable lenses or filter functions, a Polarizing filter can be installed to reduce reflection.
5. Close to the glass installation: If conditions permit, install the camera as close to the clean glass as possible, but make sure the lens does not touch the glass to avoid vibration and scratches.
6. Blocking method: Use curtains, hoods, and other items to block a part of the window to prevent external light from entering the lens. At the same time, ensure that the required monitoring area is not affected.
7. Change the installation position: If possible, move the camera to a position that does not pass through the glass and directly faces the monitored area.
8. It was optimized with infrared night vision technology. For night vision cameras, the infrared light source would not directly shine on the glass and cause reflection. Some cameras were designed with infrared filter, which could automatically switch to day and night mode during the day to reduce the reflection of visible light.
9. Choose a dedicated night vision camera: Choose a night vision camera designed for this type of application with anti-reflective capabilities. These products are usually combined with special coating or structural design to reduce reflection.
In addition, the MIT Institute of Technology had developed a new camera that combined existing depth of field sensors and advanced signal processing technology to eliminate the reflection of photos taken through glass windows and present clear images without reflection. The principle was to let a piece of glass reflect light of two frequencies, causing them to cancel each other out slightly. The camera system emitted a special frequency of light to the scene and calculated the time difference between the reflection of the light by nearby and distant objects. It used existing commercial depth-of-field sensors combined with advanced computing technology.

Surveillance camera, night glass reflection, what's going on?If the infrared camera has glass reflection at night, it may be caused by the following reasons:
1. Reflected light: The glass surface of the infrared camera may reflect surrounding light, especially at night or in the near-infrared spectrum. This reflected light could come from other lighting devices, the headlights of the vehicle, or other light sources.
2. [Normal phenomenon: Some infrared cameras have optical designs, so that light reflection at a certain angle is a normal phenomenon.] This design could improve the image quality and clarity of the camera to a certain extent.
