bsd fisheye scenes

The fisheye lens was an ultra-wide-angle lens with a focal length of about 6 - 16mm and a viewing angle close to or equal to 180°. It was named after its front lens that protruded toward the front of the lens in a parabola shape, similar to a fisheye. Using a fisheye lens in a movie could create a unique visual effect. In terms of perspective, its ultra-wide perspective could capture a very wide range of scenes. It could bring a strong visual impact to the audience in the performance of large scenes such as grand buildings, vast natural scenery, or large scenes with a large number of people. It made the audience feel as if they were in the scene and had an immersive panoramic feeling. From the perspective of image distortion, the fisheye lens would bring about obvious distortion effects. This kind of distortion had a special meaning in the movie narrative. It could be used to express a special atmosphere or character state. For example, in the movie " Village Play," the photographer Shao Dan used a fisheye lens to describe absurd events. This distortion effect might cause exaggerated changes in the shape of characters or objects, thereby emphasizing the sense of absurdity, unrealism, or complex emotions such as distortion and confusion in the character's heart. In terms of composition, due to its unique perspective and distortion, it would change the conventional composition method. The principles of balance and symmetries that were followed in traditional composition would be re-shaped under the fisheye lens. The layout of the elements in the picture would produce new visual relationships due to the characteristics of the lens. The director could use this characteristic to guide the audience's gaze, highlight the key elements he wanted to express, or hint at the special relationship between the characters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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 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>

There were many brands that supplied 360-degree fisheye cameras. For example, Joan had a 360-degree panoramic fisheye camera, and Puwei had a panoramic 360-degree network HD camera, a smart house-keeping remote Wi-Fi surveillance VR panoramic fisheye camera, and so on. These cameras usually had a panoramic surveillance function, which could achieve large-scale surveillance without blind spots. Some of them also had a variety of image display modes, video security encryption, and other functions. Different products might have differences in terms of price, image quality, and functional details. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

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>

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. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The concept of the fisheye lens was mainly based on its unique optical properties. The following are some common aspects: ** 1. Use a big perspective ** 1. ** Omnidirectional Shooting ** - In VR panoramic photography, the focal length of the fisheye lens was about 6 - 16 millimeters. The front lens had a short diameter and was protruding in a parabola shape, which was similar to a fisheye. This kind of lens could shoot a wide range of angles. For example, the angle of view could approach or exceed 180 degrees, and some could reach 220 degrees or 230 degrees. This feature could be used to create a 360° panoramic image with fewer photos, saving time and improving work efficiency. It could also save costs, reduce production costs, and improve product quality. - When shooting minimalist scenes such as shorelines and deserts, aim the camera at the horizon and keep the camera angle flat to capture the big scene. At the same time, try to avoid placing objects at the edge of the frame to avoid distortion, unless post-processing correction. 2. ** Shooting in a small space ** - Due to its large angle of view, it could accommodate more scenes in a small space and adapt to the shooting needs of a small space. 3. ** emphasize the elements of the scene ** - It could emphasize the lines in the picture. For example, in architectural photography, it could combine the elements behind it and use its transformation effect to compose a composition, emphasizing the lines in the building and creating a unique architectural photo effect. ** 2. Use the Distortion Effect ** 1. ** Close Shot ** - When shooting at a close distance, the fisheye lens could create a very strong perspective effect, emphasizing the contrast between the near and far objects, making the captured image have a shocking appeal. For example, when shooting a portrait, approaching the model could make a part of the character (such as the eyes or hands reaching out to the camera) appear particularly large, or when shooting still life, it could also increase the interest of the picture. However, when shooting a portrait, one had to ensure that the result was acceptable to the subject. - When shooting some of the texture of the background, such as the close-up of the waves and the beach, the horizon can be clearly curved to create a unique visual effect. 2. ** Creation Transformation ** - Distorting the horizon by pointing the camera at the ground or the sky, causing the horizon to curve up or down. When aiming at the ground, make sure the background is attractive enough; when aiming at the sky, shoot when the sky is full of drama. - When shooting a portrait, you can also distort the appearance of the character to obtain interesting effects, or emphasize the buildings around the model, making the character smaller in the picture and surrounded by buildings. ** 3. Use the long depth of field feature ** - The fisheye lens had a relatively long depth of field, which was good for expressing the long depth of field effect of photos. This feature could be fully utilized when shooting scenes that required a long depth of field effect. ** 4. Concepts related to special shooting techniques ** 1. ** The camera moves during exposure ** - You can deliberately move the camera, such as moving the camera during exposure. During the day, the exposure time was about 1/15 second. At night, when using a tripod, you could even try a longer exposure. Hand-held shooting could produce a radial-blurring effect (rotating the camera around an imaginary center point, maintaining the stability of the camera during rotation). Using a tripod to shoot a similar moving light effect (rotating the camera to the head of the tripod) was also a creative shooting concept. 2. ** Shooting distance control ** - Pay attention to the shooting distance, because close-up shooting can make the distortion effect of the fisheye lens more obvious. The closer you are, the more exaggerated the effect. For portrait photography, the closer the distance, the more obvious the effect of the "big-headed dog". This technique could also be applied to still life photos. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Here are some recommendations for Nikon fisheye lenses: - Nikon AF-S Fisheye Nikkor 8 - 15mm f/3.5 - 4.5E ED lens: This lens can provide round and full-picture fisheye effects. In the Felix format, when the zooming position is set to 8 mm, the vertical and horizontal (circular fisheye) shooting angles are about 180 °; when the zooming position is close to but not up to 15 mm (the shooting angle at the focal length of 15 mm is slightly smaller, about 175 °), the shooting angle in the diagonal direction (full-frame fisheye) is about 180 °. In the DV format, near the DV mark on the focal length scale, the shooting angle of the full-frame fisheye image in the diagonal direction was about 180 ° (the shooting angle of the full-frame image gradually decreased as the lens zooming ratio increased). At the same time, the entire screen area (including the largest aperture or aperture reduction) can provide high-resolution images, up to the edge of the screen to achieve a good point light source restoration ability. - Tuli AF10 - 17mm f/3.5 - 4.5 (Nikon mount): The lens is a fisheye lens (zoom). The lens mount is a Nikon F mount. The focal length range is 10 - 17mm. The lens structure is 8 groups of 10 pieces. The maximum aperture is F3.5 - 4.5, the minimum aperture is F22, and the closest focusing distance is 0.14m. The lens frame is an Abyss frame lens. The reference price is 3499 yuan. - 8mm F3.5 Nikon fisheye lens, priced at 0.0, was a super wide-angle lens. - Ming Craftsman's possible 11mm F2.8 Nikon SLR mount fisheye lens: From the warm-up chart, it could be used with old SLR cameras such as the Nikon D3X, but it was only in the warm-up stage. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The fisheye lens was an extreme wide-angle lens with an angle of 180 - 270 degrees. However, in engineering, lenses with a viewing angle of more than 140 degrees were collectively referred to as fisheye lenses. In reality, there were also lenses with a viewing angle of more than 270 degrees. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
