The camera shoots black
If you use a camera to shoot black-related objects or scenes, the following are some points to note: * * 1. When shooting black objects (such as black pets)** 1. * * Focus ** - Because black objects could not provide enough reference for autofocus, they could not identify the appearance and expression through patterns like animals with flowers and colors, so they had to use light and shadow to assist in focusing. 2. * * Photometering ** - The automatic light measurement of the equipment might not be accurate. When shooting a black object with a dark background, the camera would automatically brighten the image to show more details in the dark area, causing the image to be overexposed, turning the black into gray. Therefore, he had to make good use of the exposure compensation function (following the white plus black reduction principle). 3. * * Light usage ** - If you shoot outdoors, try to shoot under the shadows of buildings or trees, or on cloudy days, in order to avoid strong direct light that causes overexposed highlights. - If you were shooting indoors, window light was a better natural light source, but you had to use a semi-translucent curtain to create soft light, and you could adjust the distance from the window to control the angle and brightness of the light. If the light in the room is too dark, don't forget to add a soft light cover or use a flashing light when using artificial light sources (such as LED lights or small hot shoe lights). * * 2. When shooting with a black background ** 1. * * Using props ** - Black curtains, black umbrellas, black cardboard, and so on could be used to create artificial backgrounds. If it was a planned shoot, prepare a black background cloth in advance and determine the size according to the subject. When shooting, keep the black background cloth at an appropriate distance from the subject to prevent the background details from being too clear and increasing the workload of post-editing. You can also use the lens 'characteristics to blur the background with a shallow depth of field (such as a large aperture or telephoto lens). 2. * * By adjusting the parameters and controlling the angle ** - Spot photography could be used to ensure that the subject's exposure was accurate. If the background itself was lower than the subject's brightness, the background light would become darker and weaker under the camera's optimization calculation. - He was good at making use of the angle of the environment and adjusting the shooting angle to the black background. It was easier to form a black background with the spot light measurement method. - When the background of the dark part was not dark enough, the exposure compensation parameters in the camera were used to reduce the brightness. 3. * * Using the calendering technique ** - Use a small aperture, a high-speed shutter, and a low USB (such as USB 100). At the same time, use a flash to complete the calendar. * * 3. When shooting a black object against a black background (both the object and the background are black)** 1. * * Backlight Operation ** - Add a backlight to the frame and create a visible outline at the edge of the object to separate it from the background. However, it is important to note that black will actively absorb light. It may require more light sources than usual to create a visible outline, and the color will turn gray in the area where the light shines on the object. In this scenario, the lights are set from the controller to avoid backlighting (unnecessary light can be cut off using cells or black marks that help focus the beam). 2. * * Cause brightness difference ** - Make the subject slightly brighter than the background to visually separate the subject from the background.

The camera shoots the propeller
If you were shooting the propeller in the aerial image, you had to control the flight speed when flying straight forward. It was not recommended to push the propeller forward at full speed (100%), and when the camera was at a horizontal angle, this operation could easily capture the propeller in the picture. If it was to shoot a ship's propeller, it might be equipped with a propeller protection cutter (pan knife). When the rope was close to the propeller, the rope would be driven by the propeller to the island mouth and then quickly cut by the blade. However, the reference materials did not mention any special precautions or techniques specifically for shooting ship propellers. When shooting the aircraft propeller in the air show, due to the fast speed of the aircraft, the instantaneous action, the high requirements for equipment, and the need for high-end body (such as focusing speed, continuous shooting speed, and small shutter lag, etc.), it may be necessary to mount a suitable lens such as a super-long focal lens or a zooming telephoto lens to shoot. However, there was also no mention of the special points for shooting the propeller. In addition, if the flight speed was too fast, the turning speed was too fast, or the pitch speed of the cloud platform was too fast, it was easy to cause problems (such as the propeller being damaged, the image being blurred, etc.). <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The TV camera shoots the moon
Here are some of the key points of the moon shot by television cameras: 1. ** Scene Selection **: - In terms of focal length, it was best to choose a lens of 400 mm or more. If it could reach 800 mm or more, it would be more conducive to showing the details of the moon's surface. If the focal length was below 400mm, the moon would appear smaller in the picture. It could be improved by zooming in and trimming the picture or using a telephoto lens. A telephoto lens can better zoom in on the moon and capture its details because the moon is very far away from us. 2. ** Stabilizing Equipment **: - When shooting the moon, especially when using a telephoto lens, it was easy to shake when held. A tripod was needed to stabilize the camera. If there is a shutter release, you can use the shutter release to trigger the shutter. If there is no shutter release, you can use the timer function to shoot to avoid shaking when the shutter is pressed. 3. ** Shooting mode and parameters **: - In terms of mode, he could choose the M mode or aperture priority mode. The aperture was adjusted to between f6.3 and f16, and the shutter speed was chosen to be above 1/100 second. If the moon was exposed normally, the sensitivity would be set to 100. - In a dimly lit environment, one had to pay attention to the problem of overexposed. Because the actual brightness of the moon in the sky was high, too slow shutter speed would cause overexposed. At the same time, the moon was in motion, and too slow shutter speed would cause the moon to form a shadow in the picture. 4. ** Focus Method **: - Manual focus was a better choice. You could use the zooming function to focus or turn on the peak focus function to improve the clarity of the manual focus so that you could capture a clear moon. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The camera shoots the starry sky
Different cameras had different methods and precautions to take pictures of the starry sky: ** I. Use SIGMA-15mm F1.4 DG GN Diagonal Fisheye| Art lens shooting starry sky ** 1. ** The features and advantages of the camera ** - This was a fisheye lens with a 180-degree angle of view. It had high imaging quality and excellent control of the center and edge effects. Its aperture was F1.4 - F16, with 11 circular aperture blades. When shooting the starry sky, the large aperture F1.4 could allow more light to enter, and the image could be shot at an USB of 1600 without worrying about noise. For example, when taking a single shot of the starry sky, setting the focal length to 15mm (180 degree angle of view), aperture f1.4, Iso2000, and exposure time of 20 seconds would have a very good effect. Moreover, four photos could be stitched together to get a picture of the Milky Way arch bridge, which was easier to achieve than the 16 - 35mm lens. 2. ** Shooting Techniques and Problem Solvers ** - ** Depth-of-field control **: If you are worried that the maximum aperture of f1.4 will cause the depth of field of the picture to be too shallow and the ground to be blurred, you can keep the main subject further away from the lens to maintain the clear effect of the main subject and the background. - ** Focus problem **: Use the camera's zooming function to view the screen. Choose the brightest star, manually focus, and slowly adjust the star to the smallest spot on the screen. Since it was a screen shot, there would be no problem with the camera going out of focus. 3. ** Other features of the lens ** - The lens weighed 1360g, and its size were 104.0mm x 157.9mm (L mount) and 104.0mm x 159.9mm (E mount). It had a special lens ring design that could balance the weight, facilitate horizontal and vertical switching, and protect the lens. The lens structure consisted of 15 groups of 21 lenses, including 4 FLD and 3 SLD special low-dispersion glass lenses, as well as 2 aspheric lenses. The closest focusing distance was 38.5cm, and the maximum magnification was 1:16. The lens driving system was a high-speed linear motor, and the bayonet types were L and E. ** 2. Use SIMAR 14 - 24mm F2.8DG GN| Art lens shooting starry sky ** 1. ** Characteristics of the lens ** - This was a zoom lens. In order to obtain sufficient light, it had a large aspheric lens and an integrated hood ("light bulb" head). The overall size was relatively small and weighed only 795 grams. 2. ** Shooting operation example ** - It could be installed on a SonyA7M4 for shooting. ** 3. Use the iPhone to take a picture of the starry sky (using the original iPhone camera as an example)** 1. ** Porthole Shooting (suitable for shooting the starry sky outside the window on an airplane)** - He clicked on the small arrow above the shooting interface, clicked on the night scene mode button, and slid the progress bar to the right. The phone was close to the porthole. If it was blurry and could not be focused, click on the small flower icon in the lower left corner to manually turn off the macro function. After pressing the shutter, the exposure time was about 10 - 30 seconds. The color adjustment parameters of the starry sky after shooting: Color temperature-10, highlight +15, light sense +20, blue saturation in the HTL tool +3, filter: Liebilever. 2. ** Shooting in normal scenes (when no special scenes are mentioned)** - He turned on the camera and tapped on the half-moon icon (those who couldn't find the half-moon icon could find it by covering the camera). He stretched it to 30 seconds and zoomed in to take a picture. ** 4. Universal Starry Sky Shooting Setting ** 1. ** Three Elements of Exposing ** - Aperture: A large aperture (such as f/1.4 to f/2.8) can increase the amount of light entering, but try not to open it to the maximum to avoid "aberrations" at the edge of the picture. - ** Shutter Speed **: It can be set according to the "500 rule", which is to divide 500 by the equivalent focal length of the lens to get the upper limit of the shutter speed. After this time, the stars may appear smeared, but this is only a reference. The specifics will be determined according to the actual shooting effect. - ** Iso-level **: The value should be maintained between 1600 and 3200. This range can ensure normal exposure and control the image noise within an acceptable range. 2. ** Other settings ** - ** White Balance **: Choose Manual. When there is no interference from artificial light sources, setting it at about 3000K will make the screen appear colder. If there is, you can set it higher to achieve the effect of alternating between cold and warm. - ** Focus **: Choose manual focus. You can adjust the lens focus ring to infinity (infinity) and then slightly turn it back. You can also use the camera's real-time view function to magnify the starlight in the picture in a dark environment for precise focus, or find a distant bright spot (such as a lighthouse or a bright star) to focus and lock the manual mode before shooting. - ** format **: Choose the RAW format to shoot. It has more room for adjustment than the JPEG format, which can effectively improve the image quality. - ** Anti-shake **: Since shooting in the starry sky requires the camera to be placed on a tripod for stable shooting, the anti-shake function on the lens should be turned off to prevent the camera from shaking slightly and blurring the picture. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Findx6pro professional camera shoots the moon
The Oppo Find X6 Pro had many advantages when shooting the moon. It was equipped with three main cameras, each of which was the main camera. The telephoto lens was excellent at shooting the moon. Its 50-million-pel imx890 large base telephoto lens had good resolution. Coupled with the dark light telephoto technology, the phone could cope with all kinds of low-light environments to shoot the moon. For example, when shooting a full moon in a dark environment, the bright light of the moon could be suppressed just right, and the dark details could be retained to a certain extent. At the same time, the phone's self-developed chip, Mariana X, was responsible for dealing with noise and image details, and Hasse images were used to enhance the color of the photos. In actual shooting, if the zooming factor was pulled to about 60 times, the stability was very good, and it could even be pulled to 91 times. There was also an obvious calculation process to make the picture instantly clear. When shooting the penumbra lunar eclipse, the photography blogger used the OOppo Find X6 Pro to shoot multiple samples. The panoramic view and details of the penumbra lunar eclipse could be clearly seen. Whether it was the long-distance shot with low magnification telephoto or the close-up shot with high magnification telephoto, the picture was clear and transparent. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The feathers are so shiny when the single-lens reflex camera shoots them
To use a single-lens reflex camera to shoot feathers with good luster, you can refer to the following methods: 1. ** Device Selection and Setting ** - ** Choose the right camera **: There are many types of DSLR cameras to choose from, and different cameras have different image quality. - ** Adjusting aperture, shutter speed, and USB **: A larger aperture value (f/2.8 - f/5.6) can make the subject clearer; set the shutter speed according to the movement of the subject. For example, shooting birds in motion may require a faster shutter speed (telephoto lenses should generally not be lower than 800); try to lower the USB value to reduce noise. - ** Focus mode **: It is recommended to use single-point focus with the central focus point. Its focus accuracy is higher than that of multi-point focus mode. It is not easy to misjudge the focus due to interference from other objects when the lens follows the birds. If you were shooting a bird in flight, you could use the continuous autofocus mode and enable the high-speed continuous shooting function. This would capture the bird's instant clear image and make it easy to choose the highest quality photo. 2. ** Light utilization ** - ** Choose the shooting time **: The light in the morning and evening is softer and colorful, suitable for shooting. Try to avoid shooting in the direct sunlight at noon. - ** Use a reflective plate or fill light **: If the subject's face is not bright enough, you can use a reflective plate or fill light to brighten it. 3. ** Post-processing **: By adjusting brightness, contrast, sharpness, color, and other parameters, the luster of the feathers in the photo will be improved, making the photo more vivid. 4. ** Photographer preparation (for birds)**: If you want to shoot bird feathers, accurate light measurement is very important. When shooting birds with different feathers in different environments and backgrounds, the exposure of the light meter should be treated differently. For example, when shooting birds with white and bright feathers in a dark environment, the exposure should be reduced as negative exposure compensation; when shooting birds with dark and dark feathers in a bright environment, the exposure should be increased as positive exposure compensation. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
DSLR camera with black background
The following are some key points related to shooting a black background with a DSLR: ** 1. Pre-filming ** 1. ** Setting and Distance ** - The black background cloth could be used directly. When shooting portraits or merchandise, the camera could shoot directly against the black background. Be careful not to place the black background too close to the main body, or the black background would be easily captured. - If you use a black background as a background to shoot portraits, commercial photography, flower photography, etc., when shooting, pull the distance between the subject and the black background to prevent the light from hitting the subject from shining on the black background and affecting the color purity of the black. 2. ** Metering Method ** - Spot photography was often used when shooting against a black background. Generally, the reflection of 18% neutral gray was used as the basis for light measurement. High reflection would reduce the light. - If the person or object to be photographed is large and opaque, average or center-focused dimming can be used, and the exposure can be based on the measured exposure parameters. If the proportion of the object to be photographed is small, or although it is large but not in the picture, it is necessary to shoot the object after spot dimming, or temporarily put an 18% gray plate on the object to do average or center-focused dimming first. After recomposing, shoot according to the dimming data. - If you shoot objects such as transparent glasses with a black background and directly use average or center-focused dimming, you may need to reduce the exposure compensation by 1 - 2 levels to avoid the black being gray. If you temporarily use an 18% gray plate behind the glass for average or center-focused dimming, you don't need exposure compensation. 3. ** Light usage ** - The point-light method used a very small mask to measure the light in the picture. It prioritized the accuracy of the subject's exposure. When the light was measured at the bright spot of the picture, the black part of the picture became darker, thus forming a black background. You can also form a black background by shooting angle and choosing the background. When the dark background is not enough, you should reduce the exposure compensation to make the dark part darker. - The more light there is on the subject, the easier it is to get a dark background on the camera, but be careful not to cause too much light to cause the colors in the photo to look faded. - When taking portraits outdoors with a black background, you can choose a location with a dark or shadowed background. Look for places where little light shines on the background, such as a dark door, a wall, or behind a group of dark tree trunks. 4. ** camera settings ** - [** USB (Light Speed)**: Sets the USB to the lowest possible value, such as 100 or 200.] A lower IS value would make the camera sensor less sensitive to light, which could reduce the amount of light reaching the sensor, help create a black background, and also avoid the graininess of the photo caused by a high IS value. When the base IS value was 100, the clearest results could be obtained. - ** Shutter Speed **: Choose the best or fastest sync speed, usually 1/200 or 1/250. If the shutter speed was too fast (such as 1/4000), the light from the flash might not be able to enter the sensor, and if the shutter speed was too slow, too much light might enter the picture. For example, if the flash sync speed of the camera was 1/200, the shutter speed of the camera could be set to 1/100, and the flash could be turned on to take a photo to avoid the situation where the shutter blocked the flash and caused black stripes to appear on the photo. - ** Aperture **: The smaller the aperture (the larger the f-value), the darker the photo. For beginners, you can choose the aperture f/5.6 to shoot first, and then adjust it according to the results. If you see some objects on the screen, it means that there is natural light or environmental light entering the scene. You can choose a higher f-value (such as f/11.0) to reduce the aperture until the camera display is completely dark. ** 2. Post-processing ** - You can use photo editing software to adjust the picture, such as adjusting the parts that are overexposed or underexposed. If there were some exposure problems in the early stages of the shoot, or if they wanted to further improve the effect of the black background, they could do it in the post-processing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
The apple camera is especially black
There may be the following reasons and solutions for why the iPhone camera looks dark: - Lighting problem: The Apple phone's camera has high resolution. In the case of insufficient light, it may cause the skin to look darker. He had to find a good source of light to ensure that the environment was well-lit. - The camera settings: He could try adjusting the brightness and exposure compensation. He could enter the photo style option of the camera application and choose a more suitable mode. He could also open the "lens correction" in the camera. He could also adjust [settings]/[camera]/[retain settings]/[exposure adjustment], open "exposure adjustment",[settings]/[photo], and turn off "view full HPR" so that the photo would not be too sharp. When taking a photo, click on the inverted triangle symbol at the top, choose the ratio of 16:9, click on the "exposure adjustment" symbol in the upper left corner, and then slide to adjust the exposure duration to 0.3 - 0.7. - System or equipment problems: If the lens has stains or scratches, cleaning the camera may improve the effect. If all the above did not work, it might be that the system needed to be updated or the equipment needed professional maintenance. - Automatic noise reduction: Apple phones sometimes have excessive noise reduction, which can cause skin tone to look darker. - Operation tips: When using the front camera to take a photo, press the photo button and slide to the left. The skin taken will be bright and clean. When using the rear camera, you can prepare a mirror and a phone holder. Turn the phone to video mode, then turn on the flash, pull the focal length to about 1.7 - 2x, turn the phone around, point the lens at yourself, place the mirror in front of the phone, turn off the light, click on the record, and press and hold the exposure before posing. In addition, you can use a small flashlight (the kind that can adjust the brightness) to solve the problem of facial depression and photo blackness. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Black lines appear on the phone camera
The black lines on the phone camera could be caused by software or hardware problems. From a software perspective, the camera control software might have a malfunction. For example, there might be a bug in the software that caused the camera to be unable to correctly adjust parameters such as exposure and white balance, resulting in black lines. The solution was to go to the phone manufacturer's official website or app store to download the latest software version and follow the instructions to install and upgrade. From a hardware perspective, the optical components inside the camera may be damaged, causing the light to not be properly focused or transmitted to the image sensor, resulting in black lines. If cleaning the lens and updating the software could not solve the problem, the phone may need to be sent to the repair center for repair or replacement of the camera. In addition, if black lines (ripples) appear on a computer screen, it may also be related to the scanning method of the monitor (such as interlaced scanning, interlaced scanning), development time, shutter frequency, and other factors. For example, when the phone lens captured the image at a higher frequency than the refresh rate of the display screen, it might capture the scanning ripples on the screen. For the old-fashioned LCD display that used "fluorescent powder" imaging, the imaging principle could also cause obvious ripples when the phone was shot. The ripples on the screen of the LCD and LED display were usually shallow or almost invisible. If black stripes appear when shooting an OLED screen, it may also be related to the screen's strobing. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
