In the reference materials, there was a Nikon camera model of the Nikon D850, which used an AF-S Nikkor 24 - 70mm f/2.8E ED VR lens when shooting volleyball scenes; there was also a Nikon D3S shooting volleyball scenes, but the lens model was not mentioned. Nikon's 24 - 70mm f/2.8 lens was an option for shooting volleyball scenes, but this did not mean that only one lens could be used for volleyball photography. Different shooting needs and environments might require different lenses. For example, telephoto or wide-angle lenses might be selected according to the distance of the shooting, and lenses with suitable apertures might be selected according to the lighting conditions.

Industrial lenses could be used for photography. The industrial lens was a camera or photographic lens used in the field of industrial automaton. Its main function was to perform optical imaging. It was an essential core hardware in machine vision, and its image quality was affected by many factors. It could be divided into different types such as fa lens (also known as CCTV lens), zooming lens (manual and automatic), and monocentric lens (generally, there were object monocentric and double monocentric), which indicated that it could be applied to photography related work. There were also many cases of industrial lenses being used in photography. For example, some photographers used lenses removed from Ricoh photocopiers to modify the so-called "burgundy industrial lens" for filming. Some people used unnamed industrial lenses with the SonyA7. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Different shots could be used for seaside photography. If you wanted to include the sky, sea, and beach in the picture, you could choose the Canon RF24 - 70mmF2.8LIS USM lens at the 24mm wide-angle end. The water and sky behind it would make it look even more layered. If you wanted to enhance the sense of space compression and perspective in the picture, avoid the strong perspective relationship between the near and far, and express the portrait while also showing the background scenery, the standard focal length of 50mm was a good choice. In a relatively complex environment, such as a scene where the background is chaotic and it is difficult to find no one, it is recommended to use a 70mm medium telephoto focal length to highlight the main character. If you want to take photos of people interacting with the sea at close range, you can use a medium telephoto lens, RF70 - 200mmF4LIS USM. However, be aware that the sea water is corrosive to the camera, and the photographer should try to stay away from the sea water. When taking a silhouette photo or close-up capture (such as taking a photo that can be used as a social platform avatar), it is recommended to use a focal length of more than 100mm. As for the Nikon lens, the Nikkor Z DV 16 - 50mm f/3.5 - 6.3 VR and Nikkor Z 35mm f/1.8S could also be used for seaside photography. Different focal lengths could meet the needs of different shooting scenes, such as cultural scenes. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
For outdoor photography of children, 70 - 300mm telephoto zoom lens or 80 - 400mm telephoto zoom lens could be used. If there was no such telephoto lens, 50mm and 85mm fixed-focus lenses were also good choices. Amateur photographers could also consider the more cost-effective 50mm small spittoon lens. In addition, the Nikkor Z70 - 200mm f/2.8VR S telephoto zoom lens and the Nikkor Z50mm f/1.8S standard fixed-focus lens could also be used for outdoor photography. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The following lenses are suitable for traveling in the northern border: 1. 24 - 105mm or 24 - 120mm focal length lens: This type of lens covers the common focal length from wide-angle to medium telephoto. It can be used for scenery, architecture, humanities, street photography, and portrait photography. The constant f/4 aperture could ensure full focal length light control and provide a certain background blurring effect. The built-in optical image stabilization helped to stabilize the hand-held shooting. For example, Canon's RF24 - 105mm f/4L IS USM or Nikon's AF-S Nikkor 24 - 120mm f/4G ED VR. 2. 24 - 70mm focal length lens: It covers wide-angle to standard focal length, meeting most travel shooting needs. The combination of f2.8 or f/4 constant aperture and optical image stabilization ensured the quality of shooting under different lighting conditions. For example, the Nikon Z24 - 70mm f/4S had a compact and lightweight design, excellent optical performance, good sharpness, color difference control, and anti-glare ability. It had fast communication speed with the camera body and accurate focus, which was suitable for quick shots during travel. 3. 16 - 55mm focal length lens (suitable for APS-C frame): Travelers who use APS-C frame can use this lens to obtain a range of 24 - 82.5mm equivalent to the full frame, taking into account the wide angle and medium focal length. The constant large aperture of f/2.8 ensured the amount of light entering and background blurring. It was suitable for low-light environments and portrait shooting. It had excellent optical quality, high resolution, good dispersion control, and fast and quiet autofocus performance. 4. 28 - 75mm focal length lens (suitable for a variety of mounts): For example, Tenglong 28 - 75mm f/2.8 Di III VXD G2 (A063). Covering the commonly used wide angle to medium focal length, the constant f/2.8 large aperture provided light control and shallow depth of field effects. The second-generation product used the VXD linear motor, which provided fast and accurate focusing, excellent optical quality, natural colors, good edge quality, small size, moderate weight, and high adaptability. 5. 16 - 80mm focal length lens (suitable for Fuji X-mount APS-C format without reflection): equivalent focal length 24 - 120mm, covering wide-angle to telephoto, suitable for various travel scenes. The f/4 constant aperture and optical image stabilization ensured the stability of hand-held shooting and low-light image quality. The lens was equipped with all-weather protection design, excellent optical quality and rich color. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
In portrait photography, 50mm and 85mm fixed-focus lenses were more commonly used. The 50mm fixed-focus lens was suitable for a variety of scenes, such as indoor portrait shooting. Its focal length could cope with most scenes, and it could give the audience a sense of immersion in cultural photography. It could also blur the background to highlight the main body and simplify the composition. It was relatively cost-effective. However, its composition was difficult to impress. The 85mm lens was suitable for portrait shooting in a large environment. The angle of view was about 28 degrees. With a large aperture, the background could be simplified and the character could be highlighted. The background blurring effect was better. The distance from the full-body shot to the close-up was about 1.5 meters to 5 meters, which could maintain a more comfortable shooting distance. The image quality was the ceiling of the image quality of various lenses in many cases. However, its angle of view was fixed. If the shooting distance and angle were not controlled well, the image would lack variation, which would easily lead to aesthetic fatigue. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The lens halo was a common phenomenon in photography. It was caused by the lens group consisting of multiple lenses. Although the lens had high penetration, there was reflection and scattering. The light rays that did not maintain the same direction as the incident light formed a halo, and the internal reflection and scattering of the lens were the main reasons. ** 1. The factors that affect the formation of lens halos ** 1. ** Shot structure ** - The more complicated the lens structure, the more halos appeared in the image. 2. ** Focus ** - Wide-angle lenses could deal with halos better because a short focal length would make the light source look small. Telephoto lenses performed poorly and needed to be equipped with a longer hood because telephoto lenses would magnify the picture elements. 3. ** Film coating ** - Different brands of lens coating technology were different, such as Canon's NAC coating, Nikon's NCC coating, Fuji's SuperEBG coating, Zeiss 'T* coating, Pentax's Smc coating technology, etc. Multi-layer coating lens components had a greater impact on the lens halo. 4. ** Color filter quality ** - Poor quality filter would cause more light spots and ghosting in the image, which would affect the lens flare. 5. ** Dust on the lens ** - Dust inside the lens would cause more lens halos, and all lenses would accumulate dust. ** 2. Ways to avoid lens flare ** 1. ** Use the hood ** - Most lenses would be equipped with a hood, which could prevent light from shining directly on the front mirror of the lens, effectively avoiding glare, and also protect the lens in the event of a slight impact. Petal shaped lens hoods usually had a better effect than non-petal (round) lens hoods because the petal hood took into account the aspect ratio of the camera film or digital sensor. 2. ** Cover ** - When shooting, use leaves, buildings, or body parts of the character (such as the head, shoulders, etc.) to block some direct light. You can also put your hand on the lens to block the sunlight (the hand forms a "C" shape and adjust the angle until the halo disappears, but be careful not to block the lens). 3. ** Use a fixed-focus lens instead of a zoom lens ** - The structure of a fixed-focus lens was simpler than a zoom lens. There were fewer optical components and less lens halos in the image. The structure of the zoom lens was complicated. The hood could not block all stray light at all focal lengths. There were more reflective inner surfaces inside, which made it easier for the lens to glow. 4. ** Changing the angle of the camera ** - Changing the shooting angle could change the position of the light source in the lens to prevent direct sunlight from entering the lens and eliminate the lens halo. It could also be recomposed to block the light source from the elements in the picture. If the halo was strong when it was backlit, the halo would be weaker when it was changed to side backlit. ** 3. Techniques of Using the Halo of the Shot ** 1. ** Change the angle of the sun to shoot ** - When taking photos with a lens halo, you can move the shooting position left and right to block the light from the target or part of the object. If the sun was behind the subject, the subject would be more attractive under the glow of the lens. 2. ** Shooting with a zoom lens and hood removed ** - To highlight the lens halo effect, you can use a zoom lens and a wide-angle lens instead of a fixed-focus lens. 3. ** Confirm and plan the position of the lens flare in the image ** - Because the lens halo might make the photo beautiful in some corners of the picture, but not necessarily in other positions, it was necessary to outline the shooting angle and the angle of the light to take an interesting photo. 4. ** Create the required light source ** - If you can't find an ideal light source, you can create it with photography methods, such as lamps, light bulbs, studio lights, or flashes. 5. ** Find the right time to shoot ** - Light at different times had different characteristics. The light in the morning was softer. Understanding the characteristics of natural light could make interesting photos. Light at different times could bring different emotions to the image. 6. ** Backlight Shooting ** - In order to have a lens halo, the image was shot using backlighting photography, such as backlighting to create an edge light or silhouette image. 7. ** Try to move the corner to adjust the light reflection ** - Moving the corner to adjust the amount of light reflection can get the reflected light that is suitable for the image content, such as water reflection or light passing through the bridge hole. Backlight photography may require manual focus because the camera will capture areas with darker light sources. 8. ** Try different apertures ** - When adjusting the aperture, the reflected light will produce different effects. Try different apertures to get the desired effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Tilt-shift photography, also known as tilt-shift photography, was a photography method that used a shift-shift lens to create a work. The characteristics of shift-lens photography were closely related to the characteristics of shift-lens. The most notable feature of the shift-axis lens was that it could shift, tilt, or rotate the main optical axis of the entire photographic lens while maintaining the position of the camera body and the film plane, thereby adjusting the perspective relationship of the photographed image or achieving full-area focusing. The reference clear image field was larger to ensure that the main optical axis of the lens could still obtain a clear image. It was also known as the "TS" lens ("TS" is the English "tilt and shift"),"oblique lens","shift lens" and so on. The main functions of shift-lens photography were as follows: 1. Correct perspective distortion: Reflect clearly in architectural photography. For example, when using a wide-angle focal length lens to shoot the shape of a building, the lines of the building's shape would converge upward due to the perspective effect of the near and far. However, when using a shift-axis lens to shoot, it could rely on its perspective adjustment function to correct this line convergence phenomenon, so that the building remained vertical in the picture, avoiding the feeling of tilting or even tilting. 2. [Realization of regional focus: Commonly used in commercial photography for product advertisements.] By combining the pan and tilt shooting functions of the lens, while correcting the perspective distortion of the subject, it can achieve a full-area focusing effect that is difficult to achieve with ordinary photographic lenses, so that the subject near and far in the picture can form a clear image. The photos and videos taken by the shift-lens photography were like miniature models, which could fully express the feeling of a "man-made city", which was unique and interesting. After using the shift-axis photographic lens on the 35mm single-lens reflex camera, it could be equipped with the function of a large-scale combined camera to control the perspective by adjusting the leather cavity, thus expanding the scope of use of this camera. It played a major role in the field of professional photography. For example, Canon's 135mm system's original, most widely used shift-axis lens, the ts-e 17mm4L, was regarded as an artifact. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Impressionism photography originated from the Impressionism painting. In the early days, Impressionists used soft focus lenses to obtain soft and hazy images, which was a manifestation of the use of impressionist photography lenses. In modern impressionist photography, ordinary lenses could be used to create an impressionist style through some shooting techniques. For example, when using the lens, use the defocus method to pull the lens out of focus, use the aperture priority mode, and set the lens to the largest aperture.(Small numbers, such as f/2.4 or f/4) to obtain a very shallow depth of field, then switch to manual focus and turn the focus ring until the picture is blurred. By changing the focus of the same scene, you can find the degree of blurring that is suitable for the subject. You can also use the zoom lens to perform zooming and zooming continuous shooting or zooming blurring operations. When shooting, you can change the focal length of the lens (zooming in or out), so that the lens is blurred from the center to the outside, creating an impressionistic photography effect. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Here are some tips on how to use DSLR cameras for photography homework: ** 1. The camera settings ** 1. ** Shooting Mode ** - Try to use manual mode. Manual mode allowed the photographer to precisely control the camera's parameters according to the specific shooting scene and needs, while automatic mode might not be able to meet some special shooting requirements. 2. ** White Balance Setting ** - If there was a color difference in the photo, it might be caused by the use of household light bulbs or the camera's default automatic white balance setting was inaccurate. In this case, you can try to set the white balance to daylight mode, or try to take a photo in all other white balance modes to compare which mode is closer to the actual color. 3. ** Setting of the sensitivity ** - For example, the higher the value, the brighter the photo, but at the same time, the more likely it was to have noise. It needed to be adjusted together with other values (such as aperture, shutter speed, etc.). For example, for a small object, you can set it to 200, and for a large object, you can set it to 400. 4. ** Exposing settings ** - The exposure value was displayed as-0.7,-0.3, 0, 0.3, 0.7, 1, etc. The higher the value, the brighter the photo. You can set the exposure value to 0.3 during the test shoot. 5. ** Shutter Speed Setting ** - Shutter speeds such as 1/60, 1/80, 1/100, 1/125, etc. The smaller the decimal value, the slower the speed, the more light entering the camera, and the brighter the photo taken. 6. ** Aperture setting ** - The smaller the aperture value, the larger the aperture. The more light entered, the brighter the photo. The larger the aperture value, the smaller the aperture. The less light entered, the darker the photo. It was important to note that the aperture and aperture value were in inverse proportion. The value on the camera was the aperture value, and the result after the adjustment was the aperture. For example, a photo taken with an aperture value of 3 is brighter than a photo taken with an aperture value of 6. ** 2. Shooting Techniques ** 1. ** Composing Skills ** - Diagonal composition, triangular composition, and other methods could be used to make the picture more beautiful and stable. He could also try the full-body composition method. - When shooting, you can stagger the composition or capture the moment when the character walks by to create a picture-in-picture effect. 2. ** Basic principles of filming ** - To make the photo have a clear and distinct theme, whether it was a person, a still life, or an event, it needed to be clearly expressed to avoid ambiguity or all-encompassing. - A good photo must draw attention to the subject so that the audience could immediately notice the core of the photographer's intention. - It made the photo more concise and removed those elements that couldn't set off the subject or even distract attention. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
There were many types of Canon DSLR lenses for character photography. Among them, the 35mm f1.4 lens had excellent performance in portrait shooting. It could capture the delicate expression of the character and show the surrounding environment. The f1.4 large aperture background blurring effect was good, suitable for traveling portraits or indoor portraits. The 85mm f1.2 medium-focus lens could capture the details and expressions of the characters while maintaining a certain distance on the full frame. The picture was natural and realistic. The f1.2 large aperture allowed it to take bright and clear photos in low-light environments. The blurring effect was better than that of the 35mm f1.4 lens. The 70 - 200mm f2.8 telephoto zoom lens had a flexible focal length range, and the background blurring effect was better than the 35mm and 85mm lenses. It was suitable for long-distance shots such as stage portraits, athletes, concerts, etc., but indoor shooting required a large space. The EF100mm F2.8L IS USM lens could be used for macro and portrait shooting. It had double IS optical image stabilization, good sharpness and out-of-focus performance, and ideal autofocus speed for macro shooting. The ESF135mm F2LIS USM lens was a close-up shot of a portrait. It could bring a stronger sense of compression and better blurring effect. The focusing speed was fast, the lens body weighed 750g, and the image quality was excellent when the aperture was fully opened. It was sharp inside the focus and soft outside the focus. The 50mm fixed-focus lens was also commonly used for portrait shooting. The F1.2 lens with a large aperture had a better portrait shooting effect. The 50mm focal length belonged to the standard focal length, and the shooting effect was close to what the human eye could see. It would not cause space compression and could better express the surrounding environment of the subject. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
