The camera lens has the feeling of water droplets
Here are some photography techniques to create a water-droplet-like effect: ** 1. Equipment and preparation ** 1. ** Screen Selection ** - A macro lens was the ideal choice. If you didn't have a macro lens, a telephoto lens (such as 200mm) was also fine, or you could use a macro close-up ring with an existing lens. In some cases, a standard 50mm lens could also be used to achieve a certain effect. 2. ** Other Equipment ** - You can prepare a dropper or a wet sponge to create a water drop effect. The wet sponge will produce a bigger splash when it falls. If you were shooting with a camera, a wireless shutter or shutter release would help you press the shutter without touching the camera, and an external flash (with high-speed synchronization) would help you control the light and capture the moment better. For camera equipment that needed to be waterproof, waterproof measures should be taken. ** 2. Shooting settings ** 1. ** camera mode ** - It could be set to M manual mode or shutter mode. In manual mode, the shutter speed could be adjusted to 1/2000 seconds or above (if an external flash with high-speed sync function was used, a shutter speed higher than 1/250 seconds could be used), the aperture could be set to F5.6 - F8 (or adjusted as needed, such as F11 - F16 to control the depth of field), and the USB remained automatic or was set to about USB 100 - 400 (depending on the aperture, shutter, and flash intensity). If you use aperture priority mode, you can choose a small aperture like F13. 2. ** Focus setting ** - Normally, it was focused manually. If it is difficult to determine the focus before shooting, you can choose a reference object (such as chopsticks) to determine the focus, observe the position of the water droplet in advance, and then remove the reference object after focusing on it. 3. ** Continuous Shooting Setting ** - If the camera supports it, you can use H+ high-speed continuous shooting to capture the moment of water droplets. ** 3. Photographer and Scene ** 1. ** Droplet itself ** - The source of the water droplets could be ordinary colorless water droplets, frozen milk water droplets, or colorless water droplets. If you wanted a better effect, you could use glycerine instead of tap water to make water droplets. You could also add color to the glycerine. In addition, adding light to the top of the cup could make the water droplets look better. - Some special substances could be added to the water droplets, such as a small amount of protein powder or colored powder to create interesting particles that fell on the surface of the glycerine to form a special shape. 2. ** Setting the background ** - You can use the image on the computer as the background, or use the screensaver on your phone (for example, when you take pictures of water droplets on the surface of an object, the screensaver pattern on your phone can be reflected by the water droplets). - Using a large aperture could blur the background and focus on the water droplets, or using the water droplets on the window glass to focus on the window glass, using a large aperture to blur the background. 3. ** Light usage ** - Using an external flash with high-speed synchronization function, the shape of water droplets could be outlined by lighting on both sides. If there was no flash, shooting outdoors with plenty of sunlight was also an option. Different light sources (such as reflective panels, table lamps, and even mobile phone lights) can achieve different effects on the water droplets. You can also put colored cellophane in front of the flash to change the color of the image. - When shooting water droplets on the surface of an object, be careful to avoid too much direct light to avoid affecting the beauty of the water droplets. ** 4. Shooting Techniques ** 1. ** Water Droplet Creation ** - If you use a dripping device (such as a faucet, a hole in a plastic bag, or a wet rag that drops water) to drip water, try to fill the water container with water to ensure that the water droplets fall evenly and fall to the same position every time. The water container is about 50cm away from the dripping mouth to make the spray shape ideal. - When shooting hanging water droplets, you can use small fluffy branches to hang the water droplets to make the water droplets as round as possible. 2. ** Shooting angle ** - When shooting water droplets dripping on the surface of an object, you can use the camera position to eliminate the influence of the object below on the pattern in the water droplets. When taking pictures of water droplets and splashes, the camera was fixed on a tripod, and the lens was parallel to the water surface. It could capture the moment when the water droplets fell and the splashes splashed, as well as the reflection of the water surface, and take beautiful photos. Read more exciting novels for free
What is the lens of the camera lens?
Based on context alone The lens of the camera lens was made up of many different types of lenses. This included a concave lens, which had a thick middle and thin edge structure. It had a converging effect on light, which helped to focus the light on the imaging plane, making the image clear. There were also concave lenses, which were thin in the middle and thick at the edges. They had a diffusing effect on light and were often used to correct aberrations. In addition, there were also aspheric lenses. These lenses were not the traditional spherical shape. They could better correct aberrations, improve image quality, and reduce image distortion and blurring. They were widely used in modern camera lenses. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
camera lens
A lens was an optical component composed of two concentric spherical surfaces surrounding a transparent medium (such as glass). It was an important component of a camera lens. It was composed of different focal lengths, lenses, and segments. Its main function was to form images, gather light, and obtain a parallel light source. It could bend and refracted light. Different focal lengths of the lens and the use of optical methods could change the perspective effect of the picture. A good lens could make the images and images clearer and more delicate. The lens of a camera could be divided into two categories: a concave lens (thicker in the middle than the edge) and a concave lens (thinner in the middle than the edge). In surveillance cameras, there are many different specifications of lenses, such as lenses with different angles (such as 9 degrees, 15 degrees, 30 degrees, etc.), different diameter, different lamp beads (such as 3030 lamp beads, 3535 lamp beads, etc.), and there are differences in materials, processing technology, and imaging effects. Some were made of optical-grade PC material and manufactured through high-precision aspheric optical processing technology. They had the characteristics of uniform light spots and no dark corners, which could effectively improve the image quality and make the camera better in different scenes to meet more needs. In addition, there was also the emerging technology of superlens technology, which used traditional semiconductor processing technology to build nanostructures on a flat surface to create lenses. This lens was very thin, only a few hundred millimeters thick, about twice the thickness of a human hair. It could also integrate the functions of multiple curved lenses into one device, helping to solve the problem of space constraints. It might bring new development directions for camera lens technology. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How to draw cartoon water droplets?
Well, first draw an oval shape for the main part of the droplet. Next, draw a smaller oval inside to show the reflection. Add some shine on the top and bottom to give it a 3D look. Also, you can use light and shadow to make it stand out.
The camera lens changed to a projection lens
Some data showed that the telephoto projection could be used to change the camera lens into a projection lens, and a size image could be projected at a distance of 1.5 meters. He could also use a flashlight as the film's back light and a Nikon lens as the projection lens to make a simple projector and project the reverse film on the wall. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Ordinary camera lens
Generally speaking, photography lenses could be divided into the following categories: * * 1. Standard zoom lens ** 1. * * Focus range and common models ** - The focal length usually started from 24mm or 28mm, and covered the medium telephoto range of 70mm to 120mm. The common ones were 24 - 105mm, 24 - 70mm, 28 - 70mm, and so on. 2. * * Eligible Groups and Strengths ** - It was a good choice for beginners because most cameras came with standard zoom lenses. It could shoot a wide range of subjects, such as portraits, scenery, culture, and cities. It was easy to use and could meet most shooting needs. Even experienced photographers often used it. * * 2. Telephoto zoom lens ** 1. * * Focus definition and applicable scene ** - Generally speaking, a lens with a focal length of more than 200mm was called a telephoto lens. If you were shooting portraits, flowers, plants, street culture, and other topics, 70 - 200mm f/2.8 and 70 - 200mm f/4 were good choices. If you like shooting birds, lotus flowers, long-distance scenery, and other topics, you need a focal length of more than 300mm, such as 70 - 300, 100 - 400, and so on. 2. * * The camera advantage ** - It had a long focal length and could be shot without disturbing the subject. It could also bring a good blurring effect. It was suitable for street culture, bird hunting, and shooting flowers and plants. * * 3. Fixed focus lens ** 1. * * Commonly seen focal length and advantages ** - Common focal lengths were 28mm, 35mm, 50mm, 85mm, and so on. The fixed-focus lens had good imaging quality and a large aperture. It was very friendly to portraits. 2. * * Disadvantages and suggestions ** - It couldn't be zoomed, and the photographer needed to move to adjust the image. This tested the photographer's skill. If you are interested in fixed-focus lenses, you can try buying cheaper fixed-focus lenses, such as Canon's 50mm f/1.8, Nikon's 24mm f/1.8, 35mm f/1.8, 50mm f/1.8, etc. * * 4. The characteristics of lenses with different focal lengths (135-cm camera lens as an example)** 1. * * Fisheye lens (7.5 - 13mm)** - The camera had a large angle of view and a large depth of field. It could shoot a wide scene in a narrow environment. It could make the depth of the scene have a strong ratio of near to far. The image had a strong sense of perspective, but the image distortion was large, especially at the edge of the image. When shooting at close range, one had to pay attention to distortion. 2. * * Super wide-angle lens (17 - 24mm)** - A large depth of field was good for showing the subject with a large depth. A large angle of view could shoot a wider scene with a long depth of field. However, there was also the problem of large image distortion. 3. * * Wide-angle lens (28 - 35mm)** - It had a certain depth of field and a relatively large angle of view. It was suitable for shooting scenes that required a sense of space. 4. * * Standard lens (45 - 58mm, generally 50mm)** - Its focal length was close to the diagonal of the film frame used, and its angle of view was close to that of the human eye (about 50 degrees). The image quality was relatively high, and it was widely used in various photography. 5. * * Medium and long focal length lens (80 - 135mm)** - It has a good performance in portrait photography and can use perspective to produce special effects. 6. * * Long focal length lens (200mm, 300mm, 500mm)** - The small depth of field was conducive to capturing the image of the combination of virtual and real; the small angle of view could capture a large image of the scene from a long distance, and when shooting objects that were not easy to approach, it could be shot from a distance without interference; the perspective relationship was greatly compressed, and the image distortion was small, which performed well in portrait photography. 7. * * Ultra-long focal length lens (1000mm and above)** - It was suitable for shooting extremely distant objects. * * 5. Aperture of the lens ** - The aperture of the lens referred to the largest relative aperture, which was the largest aperture. It could be divided into large apertures (F1.0, F1.2, F1.4, F1.7, F1.8, F2.0, F2.8), medium apertures (F3.5, F4.5, F5.6), and small apertures (below F8). * * 6. Comparing the image quality of a zoom lens and a fixed-focus lens ** - Under the premise of the same quality and technical level, the image quality of a zoom lens was always worse than a fixed-focus lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Choice of camera lens
There were many factors to consider when choosing a camera lens. If it was shooting scenery, from a novice's point of view, although the wide-angle lens had a large scope and could shoot an imposing manner, there were drawbacks such as small changes in the image and difficult to grasp the perspective relationship. In contrast, the telephoto lens might play a greater role in scenery shooting, and the usage rate was higher. It could also take into account topics such as skits and portraits. The choice of fixed-focus and zoom lenses depended on the user's needs and the subject. The fixed-focus lens had better image quality and was suitable for portraits with high image quality requirements, which could produce better blurring effects. The zoom lens was easy to use and was suitable for traveling, street sweeping, and other scenes that required flexible shooting of various subjects. Tianya Mirror was suitable for people who pursued lightness and practicality. It had the characteristics of light weight, wide focal length coverage (from wide-angle to telephoto), and high playability. For example, Tenglong 50 - 400mm, Nikon Z24 - 200mm, Tenglong 50 - 300mm were all good Tianya Mirrors. For portrait photography, the commonly used focal lengths were 35mm, 50mm, 85mm, and 135mm. From a practical point of view, 50mm and 85mm could be chosen first. The 50mm lens could handle both indoor and outdoor shooting. 85mm was the golden focal length for shooting half-body and close-ups. 35mm was suitable for environmental portraits, and 135mm was suitable for close-ups of people. It could separate people from the background very well. In terms of movie lenses, the most important feature was the focus effect. After focusing, the focus would not change during the zooming process. This feature was suitable for live broadcasts and other scenes to avoid out of focus. In addition, lenses with different mounts (such as the EF-mount, the PL mount, the Sony-E mount, etc.) had different prices, performance, and applicable models. It was also necessary to choose a lens based on the actual camera model and other factors. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Foreground of the camera lens
In photography, the front of the camera was an important element in the composition of the picture. A lens with different focal lengths would have different effects on the background. For wide-angle lenses (such as 16 - 35mm focal length or a wider 17 - 24mm ultra-wide-angle lens), it had a larger depth of field and angle of view. This allowed the proportion of the background in the picture to be larger, and it could present an exaggerated perspective effect. It was beneficial to clearly present the subject with a large depth on the picture, and it could also shoot a wider scene in a narrow environment. For example, when shooting the interior of a building, you could use objects such as pillars close to the camera as the background, and at the same time show the distant space, enhancing the sense of space and depth of the picture. However, it should be noted that the image distortion is large, especially at the edge of the picture. When shooting at close range, you should pay attention to the distortion problem. Standard lens (focal length 24 - 70mm or 45 - 58mm, usually 50mm), its angle of view and imaging effect is close to what the human eye sees. When dealing with the background, the effect was more natural, and there was no strong perspective distortion like the wide-angle lens. It was often used for shooting a variety of subjects. The proportion of the background and the background was relatively balanced, and the image quality was relatively high. Telephoto lenses (such as lenses with a focal length of 70 - 200mm and above) had a small angle of view and a small depth of field. When the background was included in the picture, the telephoto lens could compress the space, reducing the distance between the background and the background. The ratio of the near and far was reduced, and the front and back scenes on the picture appeared very compact. This kind of lens was suitable for emphasizing the connection between the background and the background, or for creating a special atmosphere. For example, in portrait photography, the shallow depth of field of the telephoto lens was used to blur the background and highlight the main character. In photography, the reasonable use of the camera's perspective can increase the layering of the picture, guide the audience's line of sight, create an atmosphere, and convey a specific theme or emotion. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera lens changed
Here are some ways to change the scene: 1. ** inertia transition **: Use the inertia of people's thinking and visual inertia to achieve a natural transition between shots. For example, the photographer uses the process of the model crossing the stabiliser to achieve a natural transition between different scenes. 2. ** Seamless Diagonal Connection **: First, shoot a scene where the character walks sideways. Then, shoot a scene where the character stands at the three-point line and walks toward the person. When editing, he imported the video, turned off the original sound, clicked on the video bar, and changed the speed of each video to about 0.5. He clicked on one of the video bars to cut the picture-in-picture, pressed the video bar and dragged it to the position where he needed to start the transition, clicked on the mask, selected the linear mask, rotated the template line 30 degrees with two fingers and moved it to the upper right corner (or upper left corner), pulled the appropriate feathering to make the picture more integrated, added a key frame at the beginning, and then moved the mask line to the lower left corner (or lower right corner) at the position where the transition needed to end. He added music, adjusted the ending of the video to align with the music, and then imported it. 3. ** Up-and-down transition **: The photographer gradually moved the camera closer to the character (using the push-pull lens). When the camera was close to the object (such as a sunflower), the camera could be swung along with the upward movement of the object. When shooting, the stable shooting style of the iSteadyX could be set to the extreme speed style. The transition points included the speed of the camera swing should not be too slow (or accelerated later), and the camera should follow the hand swing. 4. ** Left and right swing transition **: The principle is similar to the up and down swing transition. When the previous shot ends with an upward swing, it is best to start the next scene with an upward swing. The key point of the transition is to use the same action as the previous shot as the opening to continue the next scene. The speed of the swing cannot be too slow (or faster in the later stages), and the camera moves in sync with the hand swing. 5. ** Cover transition **: The camera is temporarily covered by a specific image, and the transition is achieved through this specific image. For example, if the scene in the previous second was blocked by a drink that was gradually approaching, the next shot could naturally show the scene to another scene through this block. It could also be combined with the Inception function of iSteadyX, that is, while using Inception to shoot a rotating image, the camera was gradually moved closer to the cup to make the image more vivid and smooth. The key point was to push and pull the lens closer to an object to block the transition, and then add Inception to make the image rotate. 6. ** Overlay Occlusion transition **: The previous scene used a drink to block the transition, and the next scene used another object (such as a hand) to block the transition. Using different objects to overlap the transition, the blocking method could no longer be singular. With the help of the hand pulling action, the scene gradually zoomed out, thus explaining the environment of the character. This could also be combined with the Inception function of iSteadyX. While using Inception to shoot the rotating scene, gradually move the hand away to make the scene more vivid and smooth. The key points included pushing and pulling the mirror away from/close to an object, plus Inception to rotate the image, and using different objects to cover it. 7. ** Similar Relational Item Transfer **: Using the relationship between similar objects as the transfer medium, the camera zooms in or zooms out to complete the change of the scene, characters, environment, and other elements. 8. ** Shape-shifting, Direction-shifting, Similar Motion-shifting **: These are also transition methods, but the operation method is not mentioned in detail. 9. ** Skill-less transition-two-level shot transition **: There are requirements for the difference between the scenes of the two scenes. The scenes of the shots can be divided into far, full, middle, close, and special. The long distance and close-up are the two extremes. The huge contrast between the scenes before and after the scenes, the changes in movement, and so on, can be used to form an obvious paragraph interval, which is suitable for the transition of large segments. 10. ** No Skill Transfer-Empty Shot Transfer **: When the purpose is to portray the emotions and mentality of the character, there is an obvious interval effect when there are only scenes without characters. It can increase the appeal of the work. It is mostly used to switch to a new city in the film and television plot, and to switch between the scenes in the natural environment (such as between the sky and the desert, between the jungle and the sea). 11. ** Skill-less transition-similar transition **: Use similar shots of objects or characters in two scenes to combine together. In addition to similar conditions in terms of shape, position, location, etc., it is best to satisfy the internal connection between the two scenes. It can be used in creative advertisements, short films, vlog forms, etc. Do not force yourself to find similarities. 12. ** The transition method of the technique-Fade In and Fade Out **: Change the video's clarity. Fade In is the beginning of the second shot, and Fade Out is the end of the first shot. There are three ways to use it. Fade In is used at the beginning of the first shot; Fade In and Fade Out is used to skip the middle time, which represents the transition of two scenes in the movie or the skipping of time; Fade Out is used. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Commercial camera lens
In commercial photography, different focal lengths had different uses. For lenses with a focal length of 24 - 70mm, this was the most important lens for commercial photographers. If it was a practical entry-level user, they would generally consider a 24 - 70mm F4 lens, which was practical and cost-effective. Professional photographers would also use this focal length lens because of their work needs. It could cope with most scenes. For example, Canon had different models such as the EF24 - 70mm f/2.8L II USM, EF24 - 70mm f4L IS USM, RF24 - 70mm F2.8L IS USM, and Nikon had AF-S 24 - 70mm F2.8E VR. Different brands and models had different prices and performance (such as weight, feel, image quality, anti-shake, dark angle, distortion, etc.). The 70 - 200mm telephoto lens was mainly used for close-up shots from a distance. In scenes such as conference events, when there was a need for close-up shots and the photographer was a certain distance away from the subject and there was an obstacle in the middle, or to not interfere with the audience's experience, this focal length lens was a good choice. In still life photography, different focal lengths had their own advantages. For example, when using a single-track camera, for close-up and macro shots (such as jewelry, clocks, etc.), the Nikkor AM/ED 210mm f/5.6 lens and the Rodonsde Apo - Ronar 480mm f/8 lens could be used. For general distance shots, the Schneider Symmar-S 300mm lens was more commonly used. If the layout required more extreme perspective, a wide-angle lens as short as 75mm might be used. When using Hasse's 50MP digital back, the 120mm macro lens could produce natural perspective when taking A4-sized photos. Even at close range, the photos were very clear. 210mm and 80mm lenses would also be used. For outdoor shooting, the Nikon D3 was equipped with an older Nikkor 105mmf/4 macro lens (the newer 105mmf/2.8 lens was not recommended because it would produce vertical aberrations), as well as 45mm and 85mm focal length shift-axis lenses. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Pictures of the camera lens
The reference 3 mentioned that there was a complete picture of the lens and focal length (collection), which included the core data of the camera, the brand lens and focal length, and the frame. However, it did not mention how to obtain these pictures, so it could not provide more information about the photo lens. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
