infrared lens application
The infrared lens had a wide range of applications. It could be used for special infrared applications or as a normal lens. The details were as follows: 1. ** Surveillance Domain **: - Meet the needs of 24-hour monitoring. At night or in low-light environments, it can image through infrared light without being limited by visible light. It can capture targets at a longer distance and combine with infrared detectors to achieve target tracking, thermal imaging, and other functions. For example, in security monitoring, the surveillance camera could get a clear picture at night, and because the infrared light of the focal point of the infrared lens was consistent with the visible light, the image was clearer, and special technology was used to solve the problem of "out-of-focus" of ordinary electric zoom lenses under infrared light conditions. It could also correct the color difference of the light in the 350 - 950mm band, so that the monitoring system could have a clear image with the help of the infrared light source. - It can be used flexibly with conventional color cameras, black-and-white cameras, and day and night conversion cameras. For black-and-white cameras, because there was no infrared cut-off filter, the infrared rays in the sunlight spectrum would interfere with the image. With the corresponding infrared lens, the image quality could be effectively improved. 2. ** Biological tissue penetrating photography **: Using the strong penetrating power of infrared rays, it can penetrate biological tissues and be used in medical and other fields. 3. ** For environmental investigation **: It can be used to investigate forest and marine pollution, and obtain relevant data and images with the help of infrared characteristics. 4. ** Judicial appraisal **: The infrared lens can also play a role in judicial appraisal work, and the images taken by it can provide evidence for identification. 5. ** Machine vision **: For example, the Jinshida JSC1002 machine vision lens can be used for machine vision-related work such as infrared iris recognition. 6. ** Security equipment **: For example, the 3.6mm1/4M12 trigger small lens is used for infrared imaging in security monitoring to ensure the safety of the site.

Mobile phone external infrared lens
If the phone itself did not have an infrared function, it could be implemented through a third-party peripheral. The common way was to insert an infrared transmitter into the earphone hole of the phone to achieve an operation similar to a phone with an infrared function, such as infrared remote control and other related functions. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Single lens reflex camera, infrared camera
To set up an infrared camera for a single-lens reflex camera, you can follow the following steps: ** 1. Prepare the camera and equipment ** 1. ** Equipment Selection ** - Ordinary single-lens reflex or micro-camera imaging units would filter infrared rays. If one wanted to take infrared images, one could use an infrared filter, and the other was to modify the camera imaging unit into an infrared camera. Due to the reduced amount of light entering the infrared filter, the long exposure time, and the difficulty of focusing, many people chose to change the machine. You can choose to idle the DSLR or micro-lens, remove the low-pass filter on the imaging unit, and replace it with an infrared filter to shoot infrared works. - In terms of the band selection, if you choose the band around 590mn, part of the visible light will be involved in the exposure, and the photo will have a colored infrared effect; if you choose the band around 680mn, a small amount of visible light will be involved in the exposure, and the photo will have a half-color effect; if you choose the band around 850mn, no visible light will enter, and the photo will have a monotonous effect. 2. ** Focus setting (for infrared focus baseline setting, suitable for optical single-lens reflex cameras)** - Place a bamboo or other obvious reference object at 1.5 meters and open the aperture. This is the 1.5-meter ruler of the lens. He put on an infrared lens and took a photo every 10 centimeters with a 1.5-meter benchmark until he was satisfied with the resolution. Then, he repeated the fine-tuned ranging photography between the two most satisfactory photos to obtain the highest resolution photo. Remember the focus mark of the lens at this time (if it is X meters), then adjust the lens to 1.5 meters, and find a mark on the corresponding ring of the lens X meters (you can use paint, carving knife, color pen, etc.). Later, when taking infrared photography, he would first obtain data according to the normal focusing distance, and then manually place this data on the corresponding infrared marker. ** 2. White Balance and exposure settings ** 1. ** White Balance Setting ** - The camera's color system had changed after the change, and the white balance had to be manually set before taking infrared photos. In the infrared color system, green was displayed as white, so when setting the white balance, choose manual, let the green fill the screen, take a photo, and set it as the white balance standard. 2. ** Exposing settings ** - Aperture setting should not be too large or too small. You can try it many times. Generally, it is set to F4 - F8. Since the infrared filter darkened the light, the exposure setting could be increased by 2 - 3 stops as needed. ** 3. Selection of shooting time ** - There was plenty of infrared light at noon in summer, which was suitable for taking infrared photos. It could also be shot at other times, but the exposure time would be slightly longer or the effect would be slightly worse. Generally, after 10 a.m. and before 3 p.m., the infrared light was more abundant, which was a good opportunity to take infrared photos. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The application of the skip-axis lens
Off-axis shots were a phenomenon that needed to be treated with caution in film shooting and editing. Although jumping axes should be avoided under normal circumstances to maintain the logical continuity of the picture, it could also be applied in some special creative situations: ** 1. Direct application under special creative intent ** 1. ** Create a special atmosphere or effect ** - Sometimes, in order to deliberately create a chaotic, confused, nervous, or dream-like atmosphere, one could directly use a jump lens. For example, in the performance of a character's inner confusion or in a chaotic situation, the jump camera lens may make the audience feel the disharmony of the picture, thus conveying the character's inner state. 2. ** An innovative attempt at artistic expression ** - In some avant-garde or experimental films, the director might break the traditional rules of axis and use off-axis shots to create a unique visual style and artistic expression. This was a challenge and innovation to the traditional film language. By breaking the audience's conventional visual expectations, it triggered a deeper level of thinking or a new visual experience. ** 2. After processing (application under remedy)** 1. ** Using momentum to change the direction of the axis ** - In the middle of the two jump shots, insert a shot of a character turning or a moving object turning, thus changing the direction of the axis. This way, the transition of the original jump axis could be made more reasonable, and the audience wouldn't feel too abrupt when watching the scene. 2. ** Neutral lens inserted ** - In between two shots that were moving in opposite directions, a neutral lens with no obvious direction was inserted. For example, the front or back of a character could reduce the effect of "axis skipping". Since the neutral lens itself did not have a strong directional orientation, it could buffer the visual conflict caused by the off-axis lens to a certain extent. 3. ** With the help of people's vision ** - In the middle of the off-axis lens, insert a scene where the person's line of sight changes. With the change of the person's line of sight, change the direction of the axis and eliminate the phenomenon of "off-axis". Through the guidance of the character's gaze, the audience's attention was diverted, so that they could better accept the change in the direction of the central axis of the picture. 4. ** Close-up shot inserted ** - In the middle of the jump shot, insert a close-up or reflection close-up shot. Close-up shots could focus the audience's attention, making the audience temporarily ignore the changes in the axis direction, reducing or eliminating the visual conflict caused by the axis jump. However, the close-up shot had to have a certain connection with the front and back shots, otherwise it would appear stiff. 5. ** Add panoramic camera lens ** - Because the position of the main body in the panoramic lens, the direction of movement or action is not very obvious, even if the axis direction changes after inserting, the visual jump of the audience is not big, which can reduce the "axis jump" phenomenon. 6. ** Using the movement of the subject ** - In between the two shots that were moving in opposite directions, insert a shot that changed the motion path of the subject. For example, in the middle of two shots that were showing two people talking and jumping axes, insert a scene where one of them walked towards the other or walked to the other side of the other person, so that the shot could smoothly change. 7. ** Using a subjective lens ** - The subjective lens represented the line of sight of the person in the picture. The subjective lens was inserted between the two shots with the main body's position reversed, and the audience was guided to observe and feel things with the line of sight of the characters in the picture, thus relieving the feeling of skipping axis. You could also insert a scene where the person's line of sight changed between two shots where the subject was moving in opposite directions. 8. ** Using the motion camera to go off-axis ** - In the middle of the two shots where the position of the conversation between the two people was reversed or the main body moved in the opposite direction, a moving shot by the camera in the process of crossing the axis was inserted, thereby establishing a new axis and making the transition between the two shots smooth. 9. ** Using multi-axis cross-axis (when the subject has more than two axes)** - This method could deal with the jumping axis to a certain extent, so that the combination of the images could be relatively reasonable under the complicated axis relationship. 10. ** Use a neutral lens (axis-riding lens)** - Neutral shots were shots that were shot while riding on the axis. The moving subject in the picture was coming or going back. By inserting a neutral lens between two lenses that move in opposite directions, the sense of conflict between the opposite movements can be reduced. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The application of micro-film lens language
The application of the micro-movie lens language was reflected in many aspects. ** 1. Farewell ** 1. ** Extreme Vision and Vision ** - The extreme distance could display extremely distant scenery, in which the characters were as small as ants, and the distance would make the characters occupy a small proportion of the screen. They could be used to build a large environment and set the overall atmosphere and background for the microfilm. For example, in some nature-themed microfilms, the distant view could show mountains, forests, and other grand scenes. 2. ** Grand panoramic view ** - A picture that includes the entire subject and the surrounding environment. It is often used to introduce the environment of a film or television work. For example, when showing the city style or large-scale event scenes, the panoramic view can let the audience have an intuitive understanding of the overall environment. 3. ** View ** - Capture the whole body of a character or a small scene. You can see the character's movements and the environment. It is suitable for displaying the relationship between the character and the environment, such as the activity scene of the character in the room. 4. ** Small panoramic view ** - The actors were "indomitable", smaller than the panoramic view but relatively complete. They could highlight the main character and also take into account part of the environment. 5. ** Mid shot ** - Commonly known as the "seven-point image", it was a scene that captured the part of the character above the calf or the equivalent scene. It was a common scene for performing scenes. It could show the movements and expressions of the characters well, and at the same time, it could also reflect the interaction between the characters. 6. ** Half body view (close-up)** - The scenery from the waist to the head focused on the upper body of the character, showing the details of the character's expression and movements more clearly. 7. ** Close-up ** - Capture images above the chest, which can also be used to show parts of the scene. It can emphasize the emotions of the character or the details of the object, allowing the audience to focus more on the emotional state of the character. 8. ** Close-ups and large close-ups ** - Close-up refers to taking a close-up shot of an object, using the head above the shoulder of the human body as a reference to highlight the details of the human body, objects, or scenery. The close-up would further highlight a part of the head, body, or a certain detail of the object, such as the eyes, the bolt, etc. This kind of scene could give the audience a strong visual impact and highlight the key elements. ** 2. Shot movement (shooting method)** 1. ** Pushing the camera (Pushing the camera)** - The subject did not move, and the camera moved forward to shoot. The scope of the shot changed from large to small. It could guide the audience to focus on the main character and emphasize the importance of the main character. For example, when showing the changes in the protagonist's heart or important plot, the camera could push the camera so that the audience could gradually pay attention to the details such as the protagonist's expression. 2. ** Pull the camera (Pull the camera)** - In contrast to pushing the camera, the camera moved backward, and the scope of the camera increased from small to large. It could be used to reveal the relationship between the subject and the environment. First, the subject was close-up and then pulled to the panoramic view, so that the audience could understand the subject's environment. 3. ** Pan (Pan)** - When the camera was still, the lens could be moved left and right or up and down to show the scene space. For example, when shooting the furnishings in a room, the camera could show the corners of the room in turn. 4. ** Pan Shot (Pan Shot)** - The camera moved in a certain direction to show the scene in all directions or to track the movement of the subject. For example, the camera could follow the footsteps of the person walking on the street to show the scenery on both sides of the street. 5. ** Follow the camera (Follow)** - The camera followed the moving subject and could continue to show the moving state of the subject. It was more commonly used in chase scenes or scenes where the character continued to move. ** 3. Shot combination ** 1. ** Fade in and out ** - Fading out meant that the screen would gradually turn black until it disappeared. Fading in meant that the screen would gradually turn bright from black until it was displayed normally. This combination can be used to distinguish between different plot segments, such as indicating the passage of time or the change of scenes. 2. ** Switch ** - The most common way to combine shots was to switch from one scene to another. It was used to quickly advance the plot or to switch between different scenes and characters. 3. ** Overlapping ** - The former image gradually disappeared while the latter image gradually appeared. The two overlapped to a certain extent. It was often used to express memories, dreams, or to hint at the connection between different things. ** 4. Color usage ** - Colors were symbolic and metaphorical. For example, in the mini-movie "Detained," the color of the character's clothes and other colors contained the information that the director wanted to convey to the audience. Different colors might hint at the character's personality, plot development, or hidden emotions. ** 5. Slow motion usage ** - For example, in "Detained," slow motion could be used to deal with the movements of the characters, enhancing the film's repression and tension. Although slow motion often gave people a sense of beauty and fantasy, in this movie, coupled with gloomy music, it brought a sense of uneasiness and oppression, strengthened the dark activities of the characters 'psychology, and showed the fear behind juvenile delinquency. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
infrared camera color
Under low illumination (<0.01Lux), the infrared camera would display a black and white image. The infrared thermal imaging surveillance camera's image would be based on the temperature distribution. The higher the temperature, the brighter the color. Conversely, the lower the temperature, the darker the color. In night vision systems that used infrared light to illuminate the night, the scene was usually only rendered in green and could not display the colors visible under normal light. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Are infrared cameras harmful?
What you want to ask is whether the infrared camera is harmful. Generally speaking, the infrared camera itself was harmless when used normally. The infrared rays it emitted belonged to the category of non-ionising radiation, and the energy was relatively low. However, if the intensity of its infrared rays was particularly strong, it might make the eyes uncomfortable if it was shone directly on them for a long time, just like when the eyes were stung by a strong light. However, ordinary infrared cameras would not cause any substantial harm to people. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Downloading the infrared remote control
You can download applications related to the infrared remote control in the following ways: If you are using a Huawei mobile phone, you can search for applications related to the infrared remote control in the mobile phone's application store, such as the "Smart Remote Control" APP or the "Smart Life" APP (these two apps have infrared remote control functions), and then download and install them according to the prompts. For other brands of mobile phones, you can also search for similar functions in the corresponding mobile application store. For example, some specialized infrared remote control applications can be used to control air conditioning, television, projector, electric fan and other equipment after download and installation. It is easy to operate and has a simple interface. It may also cover a variety of brands of electrical remote control code library.
infrared camera image format
The data format of the infrared image was the same as that of the gray-scale image. It was a single-channel image. The color image was a three-channel image composed of R, G, and B components for each of the four elements. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
infrared camera chemical fiber
There was a certain connection between infrared cameras and chemical fibers. On the one hand, in industrial scenes such as Yizheng chemical fiber related equipment monitoring, infrared thermal imaging technology (infrared camera related technology) was used to measure the surface temperature of the spherical tank in order to better monitor the condition of the equipment. On the other hand, in the discussion of the One Plus 8Pro's see-through function, it was mentioned that infrared rays were limited by the wavelength and could only penetrate chemical fiber materials (such as pet). This see-through ability was limited and had to meet certain conditions. For most of the clothes worn daily (even if it was made of chemical fiber, if it was not extremely thin), there was no need to worry about being seen through. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
