Wesley fisheye lens
It was mentioned in the reference materials that an 8mm fisheye lens called "Wesley" was used for photography. It was used in conjunction with the Fuji X-T10, with an aperture of f/2.8, a single exposure of 1 minute. In addition, a 7.5mm fisheye lens named "Wesley" was mentioned for fisheye photography. However, there was no more detailed technical parameters or special design information about the Wesley fisheye lens. Read more exciting novels for free
Fisheye lens
A fisheye lens was a lens with a focal length of about 6 - 16mm and a viewing angle close to or equal to 180°. It was a type of ultra-wide-angle lens. Its front lens was shaped like a parabola and protruded to the front of the lens. It had a wide angle of view and was similar to the eyes of a fish, hence its name. It usually consists of a front group of imaging lenses and a rear group of correction lenses, and is divided into two types of half-frame fisheye lenses and full-frame fisheye lenses. It was first used in photography to create artistic photos with a large field of view and large distortion. It was also widely used in fields that required wide-angle imaging, such as surveillance, dome imaging, aerospace cameras, and other industrial, medical, and scientific research fields. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Fisheye lens drone
Fisheye lenses could be used in drones. For example, LAOWa has a 4mm F2.8 210° circular fun fisheye lens that can be used for drone aerial photography, suitable for a variety of camera mounts such as Fuji micro-single X mount, Sony micro-single E mount, etc.; Chuangan Optoelectronics developed a 0.7mm, F2.8, 210° M8 fisheye lens, which was successfully applied to the visual obstacle avoidance of drones. By installing this lens in four directions, it could achieve no dead angle image acquisition. The image could be processed to give movement instructions to bypass obstacles. It could cruise automatically with the satellite positioning system and cooperate with the ground station for image big data analysis. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Like a fisheye lens
There were super wide-angle lenses that were similar to fisheye lenses. Fisheye lens was a type of ultra-wide-angle lens. Its focal length was about 6 - 16mm and the angle of view was close to or equal to 180°. The front lens was a parabolic shape that protruded to the front of the lens, creating artistic photos with a large field of view and large distortion. It was widely used in surveillance, dome imaging, aerospace cameras and other fields that required wide-angle imaging. It was mostly used in industrial, medical, scientific research and other fields. The ultra-wide angle lens also had a larger angle of view and could cover a wider scene. It was more commonly used when shooting landscapes, buildings, and other subjects that needed to show a wide sense of space, but its angle of view and distortion were usually not as extreme as the fisheye lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is the fisheye lens a new technology?
Fisheye lenses were not new technology. In 1906, the inventor and physicist, Robert W. Wood proposed the concept of a fisheye lens and developed a lens based on how fish view the underwater world. The lens was used in the 1920s to study the formation of clouds in meteorology. Robin Hill was the first person to truly create a fisheye lens and use it for commercial use. In the 1960s, fisheye lenses began mass production. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Fisheye lens selfie comparison
The following is a comparison between a fisheye lens selfie and a normal selfie: * * 1. Image Range ** 1. * * Fisheye lens ** - The fisheye lens could capture a very wide angle of view. For example, some mobile phone fisheye lenses could reach a 198 ° angle of view, allowing more background to be included in the picture. Compared to ordinary selfies, it could show a wider surrounding environment, which was more advantageous when taking selfies with many people or when you wanted to show the surrounding scene. 2. * * Normal selfie ** - Ordinary selfies usually had a narrow angle of view, focusing mainly on the face of the person and a small area near it. Generally, it could only accommodate a small number of background elements. * * 2. Image Distortion Effect ** 1. * * Fisheye lens ** - The fisheye lens would produce a noticeable distortion effect. This distortion would cause the center of the image to be magnified, while the edges would have a strong stretch and distortion. For example, the face of a character might look normal in the center of the picture, but the facial features or body parts near the edge of the picture would be elongated and deformed, looking like a "big Japanese melon"(more obvious in a photo). However, if this kind of distortion was used properly, it could also create interesting, unique, and exaggerated visual effects. For example, it could make funny expressions or make the scene look more dramatic. 2. * * Normal selfie ** - Ordinary selfies basically did not have such a special distortion effect. The picture was relatively neat, and the character image was closer to the normal visual perception. * * 3, visual impact ** 1. * * Fisheye lens ** - Due to its special distortion and wide viewing angle, the photos taken with the fisheye lens often had a strong visual impact. The elements in the photo were exaggerated and easily attracted the attention of the audience. It was suitable for creating creative and artistic selfies or for attracting attention on social media. 2. * * Normal selfie ** - The visual impact of ordinary selfies was relatively weak, and it was more important to present the appearance and expression of the character. * * 4. The degree of prominence of the subject ** 1. * * Fisheye lens ** - Although the fisheye lens had a wide field of view, the center of the image was still relatively prominent. However, due to the distortion and richness of the surrounding environment, this outstanding effect was not as direct as ordinary selfies. When taking selfies, if you wanted to highlight yourself and show the uniqueness of the surrounding environment, a fisheye lens could be an option. 2. * * Normal selfie ** - Ordinary selfies usually placed the main body of the character directly in the center of the picture, using methods such as blurring the background (if there was one) to highlight the character itself and reduce the interference of the background. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Fisheye lens night view
The fisheye lens had its unique performance and application in night scenes. The fisheye lens had a wide angle of view, some of which could reach 180 degrees or even more, allowing it to capture a very wide scene when shooting at night. The images captured by the camera had a distortion feature. This feature could turn a normal straight line into a curve, resulting in interesting visual effects. For example, the city at night was shot into an effect similar to "Earth's night scene." However, using a fisheye lens to capture night scenes also had some challenges. For example, some fisheye lenses had a fixed aperture (such as the Rock Star 10mmF8 fisheye lens). If you didn't have a tripod to help you shoot at night, increasing the USB to ensure enough light would bring more noise. In order to overcome the problem of shooting at night and to bring out the creative effect of the fisheye lens, some equipment used a variety of technical means. For example, the iQOO 9 Pro's 50-million-pel 150-degree fish-eye ultra-wide angle lens had excellent performance in dark light imaging. Its main camera had a large base pan head and high resolution, which helped capture rich details. The sensor had excellent dark light sensitivity. The lens used special coating and various algorithms to suppress noise, improve ghostly shadows and glare. It also provided special fish-eye effect modes such as crystal balls and asteroids, adding creativity and fun to shooting night scenes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The phone is connected to the fisheye lens
At present, there were two main ways to connect a phone to a fisheye lens: one was to install an external lens directly on the phone lens, which could be fixed to the phone lens according to the instructions; the other was to use the built-in special effects of the phone APP, which required the corresponding fisheye effect to be turned on in the camera app. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
