low angles Depth of field becomes more apparent when shooting at low angles. By adjusting aperture and focus, you can control the range and effect of depth of field. Large aperture lenses and short focal length lenses produce a shallow depth of field, making the subject clear and the background blurry. This can highlight the details and three-dimensionality of the object being photographed. lifting and lowering The high-resolution lens with a head-up lift faces forward horizontally, which is suitable for capturing close-up details of tall buildings, or reflecting the magnificent high-altitude view after passing through the obstruction of the low-altitude view. Raising the lens can create the visual effect of the opening layout, while lowering the lens implies the end and the end of the aerial photography. The up-and-down megapixel lens is directed vertically downward, which is suitable for capturing the effect of looking down at everything on the ground from a God's perspective, and switching between local parts of the ground and panoramic views. If you add the clockwise or counterclockwise rotation of the aircraft during the upward and downward viewing process, the spiral effect can enhance the coolness of the picture. surround Surrounding camera lens is suitable for portraying the subject in all directions and angles, making the subject image more three-dimensional and vivid, allowing the audience to clearly understand the background environment around the subject. A surround lens allows you to capture a panoramic view so that all desired objects appear within the field of view. dive and fade away It is actually a combination of direct flight and lifting. While the aircraft retreats and advances, it performs lifting and lowering motion shots, so that the center of gravity of the picture is always kept on the subject. Fading away is suitable for shooting scenes that convey the overall environment from the close-up to the distant view of the subject, creating a condescending atmosphere, while swooping is just the opposite. Fading away or swooping shots often have a speed change process along the path to achieve a strong visual impact. Like a fisheye lens, it brings different visual effects to people. side flight The camera is facing the subject, and the aircraft is shot from the left or right side of the subject, flying straight to the other side. Compared with horizontal panning, sideways flight enhances the range of motion and sense of speed in shooting. In addition, you can also take simultaneous follow-up shots of the side of a moving subject to create an immersive visual experience. The drone flying sideways is like a recorder lens, recording the appearance of things to make the imaging more complete. panning The aircraft hovers in the air and moves its head left and right or up and down to take pictures. Panning is suitable for shooting scenes with a wide horizontal or vertical field of view. In the same geographical location, it can gradually display the complete space and explain more picture information. In addition, it can also be used as a shooting technique to gradually reveal the suspenseful atmosphere. Like a surveillance camera lens, it gives people a scary feeling that everything about them is being monitored.

Camera module refers to the focal length camera lens system integrated in mobile phones, tablet computers, digital cameras and other devices. It usually consists of multiple components, the most important of which is the imaging lens. The function of a camera lens is to capture light and focus it on the image sensor, resulting in a clear image. Here are some common functions of a camera lens:   Focus: The security camera lens can change the focus distance by adjusting the position of the lens element, so that the subject and background can be kept clear. Generally, the autofocus function can automatically adjust the focus settings according to the shooting scene.   Aperture: Aperture controls the amount of light entering the CMOS lens. It can control depth of field (clarity of foreground and background) and exposure (brightness of image) by adjusting aperture size. Larger aperture allows for shallow depth of field and better shooting in low light conditions.   Focal length and zoom: Some surveillance camera lenses have the function of adjustable focal length, which can achieve optical zoom. By changing the degree of focus of the lens on the light, subjects at different distances can be photographed, and the scene can be narrowed when shooting distant subjects.   Lens coatings: lenses with filters may be coated with a special coating to reduce light reflection and scattering, thus improving image clarity and contrast. These coatings reduce light loss and improve image quality.   Stabilization (optical or electronic): Some M12 mount lenses have image stabilization to counteract shake during handheld photography, resulting in a more stable image. Optical image stabilization uses a stabilization mechanism inside the lens, while electronic image stabilization relies on the movement of the image sensor to achieve stability.   Field of view: The field of view of a camera lens refers to the horizontal and vertical range that the lens can capture. A fisheye wide-angle lens can capture a wider scene, while a smaller field of view is suitable for scenes that require more detail and magnification.   These functions can be achieved through the coordinated work of multiple parts in the camera module, such as lens elements, focus motors, and aperture control. Different camera modules may have different specifications and functions, depending on the purpose for which the device is designed.

A wide-angle camera lens is a photographic lens with a focal length shorter than a standard lens, a viewing angle larger than a standard lens, a focal length longer than a fisheye lens, and a viewing angle smaller than a fisheye lens. A fisheye camera lens is a lens with a focal length of 16mm or less and a viewing angle close to or equal to 180 °. It is an extreme wide-angle lens, and "fisheye lens" is its common name. The difference between the two: Field of view: Fisheye lenses have a very wide field of view, usually more than 180 degrees, and can capture a very wide scene, or even show a fisheye effect, that is, the center of the image is stretched and the edges are curved. The field of view of wide-angle lenses is usually between 90 degrees and 120 degrees, and the captured scene is wider, but not as wide as fisheye lenses.   Perspective effect: The lens design and field of view of the fisheye lens are special, and the captured image will produce a curved perspective effect, making the object in the center of the image appear larger, and the object at the edge will be stretched to create a unique effect. The wide-angle lens can also capture a wide scene, but generally there will be no curved perspective effect.   Distortion effect: The fisheye lens has a very obvious distortion effect, the image shows a curved shape, the center part is relatively normal, but the edge part will be stretched and distorted. The distortion effect of the wide-angle lens is relatively small, and the shape of the image is closer to reality.   Focal length selection: Fisheye lenses usually have a very short focal length, often between 8mm and 16mm, which allows them to capture very wide scenes. The focal length of wide-angle lenses is relatively longer, generally between 20mm and 35mm, and some lenses even exceed 50mm.   Purpose: Application examples of wide-angle lenses: Landscape photography: A wide-angle lens can capture vast scenes such as vast skies, beautiful mountains, and magnificent beaches. It can help photographers incorporate more elements into the picture to create a broad landscape effect. Architectural photography: Wide-angle lenses can capture the general outline and texture of a building, making it look grander and larger. It allows photographers to capture entire buildings in tight spaces, such as cathedrals, skyscrapers or narrow streets. Interior photography: In indoor environments, wide-angle lenses can capture more details, making them suitable for photographing interior design, museums, galleries, and other indoor venues. They can bring out the atmosphere and layout of the entire space. Vehicle cameras: They are usually installed in the front and rear parts of the car to increase the driver's field of view and improve safety. It can be turned into rear monitoring camera lenses, car reversing aid camera lenses, fatigue monitoring camera lenses, blind spot detection lenses, driving recorder camera lenses, driver security cameras lenses. Smart home: Wide-angle lens can be used for smart home security camera lens. Perform environmental awareness, real-time positioning and tracking, and enhance virtual reality experience.           b.Application examples of fisheye lenses: Photography and filmmaking: Fisheye lenses are often used in photography and filmmaking to capture a very wide range of scenery or scenes. They are widely used in sports events, travel documentaries, outdoor sports dv camera lenses and other fields to present unique and exaggerated visual effects. CCTV cameras: Fisheye lenses play an important role in traffic monitoring systems. Installed in areas such as intersections, parking lots or prisons, it can provide a full range of monitoring views, thus enhancing security and surveillance effects. Astronomy: Astronomers use fisheye lenses to observe the sky, especially for capturing images of the stars throughout the sky. These camera lenses capture a wide view of the sky and are useful for studying celestial bodies such as galaxies, planets, and nebulae. Scientific research and industrial applications: Fisheye lenses also play an important role in scientific research and industrial applications. For example, they are used in aerial surveillance, intelligent machine camera lens vision systems, drone camera lens navigation and other applications in the aerospace sector.

Wide-angle Lens: A wide-angle lens has a wider field of view and is suitable for shooting scenes such as landscapes, buildings, and large groups. It can also be used to create special perspective effects. Portrait Lens: Portrait lenses usually have larger apertures and focal lengths, such as 50mm f/1.8 or 85mm f/1.4. These lenses can produce a shallow depth of field effect, making the subject stand out from the background. fixed focus lens: fixed focus lenses have a fixed focal length, such as 35mm, 50mm, or 85mm. They typically have wide apertures and offer excellent image quality and good low-light performance. Telephoto Lens: A telephoto camera lens has a longer focal length, such as 70-200mm or 100-400mm, and is suitable for shooting distant subjects, such as sports events, wildlife, etc. Macro Lens: Macro lens is specially designed for photographing very small subjects, such as insects, flowers, etc. They offer high magnification and excellent detail capture. Fisheye Lens: Fisheye lens has a large viewing angle and can capture panoramic images or produce strong distortion effects. It is often used for creative photography or specific shooting needs.

In summary, by choosing lenses with high definition, wide-angle field of view, good low-light performance, anti-shake function and other characteristics, you can get better recording effects, improve driving safety, safeguard legal rights and interests, and facilitate insurance claims. Therefore, when purchasing a dashcam, be sure to pay attention to the quality and performance of the optical lens.  

² Take advantage of close-ups: Fisheye lenses are great for close-ups because they capture a wide field of view, and 360-degree VR panoramic camera lenses can have everything you want. Shooting close to the subject makes the subject stand out and creates a sense of depth in the frame.   ² Look for curves: One of the hallmarks of a fisheye lens is its curvilinear effect. Look for elements with curved and curved shapes such as roads, rivers, bridges and buildings that create interesting twists and curves under a fisheye lens. Customizing the lens you need can achieve the degree of curve bending you want.   ² Utilize symmetry: A fisheye lens can enhance symmetry by finding subjects with symmetrical shapes, such as buildings, bridges, flowers, etc., and placing them in the center of the lens to create a striking symmetrical composition.   ² Utilize center point perspective: Placing the subject in the center of the frame highlights the center point perspective effect of the fisheye lens. By placing the subject in the center, elements in the background can be diffused around to create a dazzling effect.   ² Multi-angle shooting: The fisheye lens is great for trying out various angles and shooting positions, and the M12 mount can achieve camera stability. Try shooting different angles of the subject, such as looking from bottom to top, from above, or squinting for a unique perspective effect.   ² Control the light: Fisheye lenses easily capture changes and reflections in the surrounding light. Pay attention to the direction and intensity of the light when shooting, avoid overexposure or darkness, and use the difference in light to enhance the picture effect.   ² Emphasize close-up and long-range views: The wide-angle field of view of the fisheye lens allows both close-up and long-range views to be presented in the picture at the same time. Try to place close-up objects in the foreground, and use long-range elements to enhance the depth of field effect, creating a rich sense of hierarchy.
