shooting star lens

For star photography, the 14 - 24mm f/2.8G ED lens was the standard for architectural photographers, landscape photographers, and starry sky photographers. Its large aperture (f/2.8) helped to increase the amount of light entering in low-light environments (such as shooting stars), and the 14mm super wide angle could capture a wider view of the stars. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

It cannot be used on other Canon cameras. - <<PR>: Canon's Eos R series full-frame micro-lens. It cannot be used on other Canon cameras. There were also MP-E (specialized for macro photography) and TS-E (electronic controlled shift lens), two special products. - ** focal length of lens **: A small number means a wide angle of view, and a large number means a good telescope. The focal length in the lens model is the physical focal length. For non-full frame cameras, you may need to consider the equivalent factor conversion according to the camera model. - ** Maximum Aperture **: For a zoom lens, if it is in the form of "f/2.8", it means that it is a constant aperture lens, and the entire focal length range can be set to this aperture; if it is similar to "f/3.5 - 5.6", it is a floating aperture lens, and its maximum aperture changes over the entire focal length range. - ** Lenses Grade **: L (Luxury) means Canon's high-end lenses, which are red circle lenses. These lenses usually have a red decorative ring at the front. - ** Image Stabilizer **: The IS (Image Stabilizer) logo indicates that the lens is equipped with Canon's unique image stabilizer, which can offset the image blurring caused by hand shaking within a certain range. It is commonly used in Canon's high-end professional lenses. - ** Focus motor **: - USM (Ultra-Sonic Motor): The lens using USM technology can achieve silent and fast-response autofocus. It is divided into three types: micro, ring, and NANO. - <strong></strong> - ** Other Marks **: - AL: It means that aspheric lenses are used in the lens design, which can reduce the number of lenses, reduce weight and volume, and provide better optical performance. It is used to solve the problems of glare and edge distortion in wide-angle and zoom lenses. It can also improve the optical quality of telephoto lenses. - DO: Lenses marked with this logo are equipped with multi-layer reflective lenses, which have the characteristics of fluorite and aspheric lenses. They are generally high-end lenses. - EMD: It means that the lens can open and close the aperture by electronic control. - Float: When the lens is used for close-up shooting, the lens will compensate for the aberrations at close range to obtain better image quality. - XP: The lens with this logo is a high-end professional lens. It has a focus presetting function that allows the lens to remember a certain focus distance. After setting it, it can automatically return to the set focus distance. It is also effective in manual focus mode. - FT - M: A lens with full-time manual function.

The best shooting distance of the lens was affected by many factors, and it was difficult to give a fixed value. In terms of focal length, lenses with different focal lengths had different characteristics. For example, in portrait photography, the distance from the whole body to the close-up shot with an 85mm focal length was about 1.5 to 5 meters. The 35mm-85mm focal length commonly used for portraits was not only close to the human eye, but also the shooting distance. The closest focusing distance of different lenses refers to the straight-line distance from the focal plane of the object to the focal plane of the image. The closest focusing distance of different lenses is different. Generally, the longer the focal length of the lens, the longer the closest focusing distance; the shorter the focal length of the lens, the shorter the closest focusing distance. However, this rule does not apply to macro lenses. The closest focusing distance is usually marked on the lens. There was no maximum focusing distance. The " infinity " on the lens indicated infinite focusing. When the focal length of the lens did not change, the shooting distance determined the size of the scene. It could be divided into long-range, panoramic, mid-range, close-up, and close-up. Close-up shooting was close, the subject was large, and the scope of the scene was small; long-distance shooting was far, the subject was small, and the scope of the scene was large. In surveillance cameras, the focal distance of a 2.1mm lens was 3 meters, and the focal distance of a 25mm lens was 80 meters. The larger the lens, the farther it looked, but the smaller the angle. Its effective range changed according to the size of the lens, generally within 100 meters, and its range was also variable when the lens was variable. The magnifying factor of the lens was approximately equal to the ratio of focal length to object distance. As the focal length increased, the magnifying factor increased, allowing the close-up view to be zoomed out and the details in the distant view to be clearer. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

In jewelry shooting, macro lenses were recommended. For example, Canon's EF100mm f/2.8L MCROIS USM or RF100mm f/2.8L MCROIS USM. Nikon and other brands also had similar macro lenses to choose from. The macro lens could capture the details of the accessory well and highlight the creativity of the designer. In addition, you can also use a conventional lens with a close-up lens to shoot. For example, a NiSi close-up lens with a 70 - 200mm and 24 - 105mm lens can also achieve a shooting effect close to a macro lens to a certain extent. At the same time, like the 60-million-pel portrait focus dual camera configuration on the front of the Huawei nova 13 Pro, it could be used perfectly from 0.7x to 5x zoom. It could also be used for close-up shooting of accessories, and some mobile phone lenses could also achieve good results when shooting accessories, especially for some jewelry shooting scenes that were not particularly demanding or needed to be quickly shot. The mobile phone lens could provide a convenient way to shoot. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some of the camera design ideas for the storefront scenes: ** 1, panoramic view ** 1. ** Purpose * - It was used to describe the overall appearance, location, and surrounding environment of the store. For example, the street where the store was located, the surrounding buildings, the signboard of the store, and whether there were parking lots and other supporting facilities. 2. ** Shooting Method ** - He could use a horizontal shooting method from across the street to ensure that the entire store and important elements were included in the picture. If you want to highlight the height of the storefront, you can use an upward angle; if you want to show the integration of the storefront and the surrounding environment, you can choose a slightly higher angle. ** 2. Mid shot ** 1. ** Purpose * - The focus was on the main parts of the store, such as the entrance of the store, the display window, or the special decorations in front of the store. This helped to attract the attention of the audience to the key areas of the store. 2. ** Shooting Method ** - Shoot from the front or diagonally in front of the store to ensure that the key parts are clearly presented. You can move the camera during the shooting process, such as pan from left to right, to show more details. ** 3. Close-up shot ** 1. ** Purpose * - It was used to focus on specific elements of the store, such as the unique logo on the store door, the main product in the window, or the welcome slogan at the door. These shots allowed the audience to get a closer look at the characteristics of the store. 2. ** Shooting Method ** - Directly aim at the target element to shoot. Pay attention to the accuracy of the focus to ensure that the image is clear. You can use a shallow depth of field to highlight the main body and blur the background. ** 4. Close-up shot ** 1. ** Purpose * - Capture the most attractive details of the store, such as the exquisite details of the goods, the unique font on the signboard, or the exquisite handle on the door. Close-ups could increase the visual impact of the scene and attract the audience's interest. 2. ** Shooting Method ** - Shoot close to the details of the target. Use the macro function (if the camera or phone supports it) to better show the tiny details. ** 5. Multi-angle lens ** 1. ** Purpose * - Shooting the storefront from different angles could provide a more comprehensive perspective and avoid visual fatigue from a single angle. At the same time, it could also show the three-dimensional structure of the storefront. 2. ** Shooting Method ** - In addition to shooting from the front, they could also shoot from the side, diagonally, or even from inside the store. For example, he could shoot the shop sign through the window and use the reflection of the glass to increase the layering of the picture. ** 6. Mirror Manipulation Technique ** 1. ** Pan Move Mirror ** - When shooting the signboard, window display, and other parts of the store, the camera could be moved slowly from left to right or from right to left so that the audience could gradually view the various elements of the store. 2. ** Roll the mirror back ** - When shooting the interior environment of the store, such as the hall or the private room, you can use the tilt mirror to show the feeling of the entire space. First, the camera focused on a part, then panned up or down, and finally panned back to show a larger spatial range. 3. ** Around the mirror ** - For some special decorations or important goods in the shop, you can use the revolving mirror to highlight their importance. Slowly move the camera around the target element, allowing the audience to look at it from all angles. ** 7. Potential for use ** 1. ** Purpose * - It added a layered and cinematic feel to the scene. 2. ** Shooting Method ** - When shooting the signboard of the shop, you could look for leaves and other things as the background, and then shoot the signboard. This would make the picture more rich. When shooting the hall environment, he could also use the background to block it and then blur it. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

There were some important points to consider if one were to use an 800mm lens to shoot deep space. First of all, pay attention to the focus setting of the lens. For a lens like the RF800mm F11IS ATM lens, the focus distance range selection switch is very important. For example, when it is selected at Full, the focus distance range is 6 meters to infinity, and the closest focus distance is about 6 meters. Below this distance, you can't focus. You can also choose the focus range from 20 meters to infinity to avoid some interference elements. At the same time, you must understand the operation of the locking ring when you use it for the first time. When the lens is not in use, keep it in the shortest state. Before using it, you need to unscrew the locking ring, extend the lens, and then lock the locking ring before you can shoot. If you want to take a photo, you may need to prepare in advance to avoid wasting time. In addition, if you use a telescope with an equivalent 800mm focal length lens (such as a 500mm telescope, a single-lens reflex half-frame multiplied by 1.6 equivalent 800mm lens), you may need to trim the moon to get a full picture. If you want to shoot Jupiter, nebula and other deep space celestial bodies, you can also consider using the eyepieces to increase the focal length, but the focal length may cause the image quality to deteriorate. When shooting, you also need to consider the camera's settings. For example, for a single-lens reflex camera with an infrared cut-off filter, if you want to better capture the nebula in the deep space celestial body (because of the low transmission rate of the band), you can consider changing the astronomical machine (changing the infrared filter to glass, the cost of changing the machine is about 800), and you can correct the red color problem after changing the machine through white balance. When shooting, you should also pay attention to choosing the appropriate shooting location (avoid light pollution, choose suburbs or scenic spots, etc.), time (avoid the full moon, different celestial bodies have different optimal observation times, such as the Milky Way is more brilliant from April to September, the 25th to the 5th day of the lunar calendar is more suitable for shooting the Milky Way, etc.), if you need better image quality, you can also consider using the equator to overcome the influence of the Earth's rotation on the stars. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

The following are some of the parameters of the DSLR camera when shooting with flash: ** 1. Night Portrait Shooting parameters ** - [Mode: Able to use Av (Aperture priority mode).] - [Light sensitivity: 100 - 400] - Aperture: around F8. - Flash mode: Use slow sync flash (the camera's default flash mode for night portrait mode. The flash flashes once when the shutter is pressed and again before the exposure ends). ** 2. The possible parameters of flash usage in different scenarios (comprehensive consideration)** - Shutter speed: The shutter speed will affect the brightness of the background. When using the flash, you also need to set it according to the needs of different scenes. For example, when shooting a baby/pet, the shutter speed should be above 1/200.(In the case of using the flash to supplement the light and need to take a photo, the high-speed shutter can freeze the instant action and avoid blurring due to hand shaking or pet movement.) - Aperture: Affects the brightness of the subject and the effect of blurring the background. For example, the aperture for indoor portrait shooting is below F2.8 (a large aperture can allow more light to enter the camera when there is insufficient light, and at the same time, it can blur the background and highlight the subject); the aperture for still life/food shooting is between F1.2 - 4; the aperture for night shooting is F10 or smaller (a small aperture can allow the depth of field to be larger, so that the entire night scene can be clearly captured). - Photosensitivity (USB): Affects the overall brightness. For example, for indoor portrait shooting, USB 1500 (indoor light is usually dim, so increasing USB can make the picture brighter, but too high USB may bring noise), while for baby/pet shooting, USB 100 - 800, still life/food shooting, USB 100 - 400, night shooting, USB 100 (Under the condition of ensuring sufficient exposure, try to use low USB to reduce noise). At the same time, he also needed to consider the white balance.(For example, the automatic white balance is the default setting of the camera. You can also customize the white balance according to the ambient light to ensure the accuracy of the color), Metering mode (There are evaluation, partial, spot, and center-focused average measurements. Different settings can be used to accurately expose different settings), exposure compensation (if you feel that the photo is too dark or too bright, you can further adjust the brightness of the photo), flash compensation (change the output intensity of the flash, usually used to adjust the brightness of the photo when filling up the light), and other parameters. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
