What's the use of iPhone 12 pro time-lapse photography?
The iPhone 12 Pro's time-lapse photography can compress long videos into shorter videos for playback. It could be used to shoot scenes such as sunrise and sunset, plant blooming, etc. It could also be used to shoot urban scenery, natural landscape, biological dynamics, astronomical phenomena, etc. The principle was to connect a single still image to create a dynamic video, similar to the production of stop-motion animation. Through regular and intermittent recording, the slow change process of the scene was reproduced with obvious changes in the image. For example, the slow process of the blooming of the flower buds could be filmed every half an hour, and the slight changes in the flowering movements could be recorded in sequence. Finally, the projector could be used to replay the entire process of blooming in a short period of time. Read more exciting novels for free
Time-lapse photography of Earth
There were many ways and results to time-lapse photography on Earth. For example, the photographer used the equator to offset the changes in the starry sky caused by the Earth's rotation by rotating at a constant speed, thus capturing the Earth's rotation. NASA's astronaut Christina Kirk took time-lapse photos of the Earth and other stars from Namibia to the Red Sea from the International Space Station. A total of 400 photos were used. The duration was 11 minutes, and the orbit of the stars, ground light sources, lightning in thunderstorms, atmospheric glow, and the orbit of artificial satellites could be seen. The Japanese weather satellite, Sunflower 8, took more than 24 hours to take photos and was produced into a 12-second time-lapse video by Charlie Loyd, a satellite imaging expert at Mapbox. The Western Pacific Ocean, Australia, some parts of Asia, Antarctica, and Antarctica could be seen. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Time-lapse photography on the Bund
In layman's terms, time-lapse photography was to first take photos at a lower frequency or record videos at a lower frame rate, and then play the images at a normal or faster speed. For example, there was a time-lapse video of Magic City on the Bund. It was the first time to try time-lapse photography with a DSLR as the main equipment. It mainly used fixed camera positions and large-scale moving time-lapse, and some of the materials were shot with an iPhone. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Time-lapse photography, shooting clouds
Here are some key points for time-lapse photography: - [Equipment and preparation: You can use a mobile phone. If possible, you can equip it with a stand or a 720 cloud mobile phone electric head (in addition to special shooting functions, it can also act as a common video shooting stabilizing device).] - Shooting operation: Find the time-lapse photography function in the camera, turn on the 0.5x super wide angle (an operation method), point the lens towards the sky, click the sky focus and press and hold to lock the exposure, then click start shooting. The phone had to be fixed when shooting, and it could be kept stable with the help of a stand. In terms of shooting time, half an hour was better, and about 10 - 30 minutes was fine. - Effect optimization: If you want to achieve the realistic feeling of clouds moving, you can change the speed when editing the video. For example, 6x speed can show the feeling of clouds galloping and electricity galloping. If you wanted to create the effect of the cloud moving fast and the person moving slowly, you could shoot a video of the character after shooting the cloud (such as a video of the character sitting and looking up at the sky). Then, you could use the editing software to import the two videos, turn off the original sound, cut the cloud video into a picture-in-picture, choose a linear mask, adjust the mask line to the intersection of the character and the sky, pull a little feather to blend the image, and finally add music to export. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Time-lapse photography algorithm for shooting stars
Different phones had different algorithms. For example, if the Huawei Mat30 series detected a starry sky scene, the algorithm would set the corresponding long exposure and isa, and use the AI network to enhance the starry sky scene, providing users with full-scene automated 4K photo-level time-lapse photography capabilities; The Nubian Z60 Ultra software was known as the custom-made upgrade of the twelve starry sky algorithms. For the first time, the Milky Way night scene algorithm was optimized and adjusted on the ultra-wide angle. At the same time, it provided a variety of starry sky color styles. Through fast fog removal calculation, it could effectively avoid the color cast problem caused by light pollution. Its starry sky time-lapse photography could capture a dreamy dynamic starry sky with one click. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

How should time-lapse photography look good?
Here are some ways to take a good time-lapse shot: - ** Equipment and stability ** - ** Equipment selection **: Mobile phones, DSLR, and micro cameras can be used for time-lapse photography. Use a stable tripod and shutter release to secure the camera, which will help reduce the image shake. If you use a tripod to shoot in a windy or uneven environment, you can hang a load to increase stability. Some DSLR cameras can be shot with a timed shutter release when there is no interval shooting function. For mobile phones and some micro-cameras, you can also shoot directly with a time-lapse photography app. - ** Focus and composition **: You can turn on autofocus first and let the camera focus. Then, turn off autofocus and switch to manual focus. In terms of composition, focus on the point of interest in advance, lock the focus and turn off the autofocus to avoid focus drift during the shooting process. - ** White Balance and Color **: Set manual white balance or custom color temperature to maintain the color of the entire sequence. - ** In terms of shooting skills ** - ** Daytime Shooting **: The exposure mode can be set to aperture priority mode, the white balance can be set to auto, and the IQ value can be lowered as much as possible. The shutter speed should be slowed down as much as possible, for example, using a speed below 1/50 seconds. This would make it easier for post-editing and the image would be smoother. Otherwise, if you shot at a high shutter speed of 1/1000 seconds or 1/2000 seconds, you would get a frozen instant image, which was not conducive to making a flowing film. - ** Metering mode **: It is recommended to use full/average dimming (matrix dimming, weighing dimming). Due to the long shooting time of time-lapse photography and the constant changes of the scene, using center-focused dimming or spot dimming may cause errors in dimming, causing the bright parts to be too bright or the dark parts to be too dark. - ** exposure compensation **: Generally, if you reduce the brightness by about 0.3EV, the color of the picture will be more saturated; if you don't add or reduce the brightness at all, the overall color will be dull. - ** Use the ND filter (if possible)**: One of the difficulties of time-lapse shooting is that the exposure time is too short. Using the ND filter to slow down the shutter speed can make the object in the picture feel "moving", avoiding the situation where the object suddenly appears and then suddenly disappears in the previous picture. - In terms of subject selection, the clouds in the sky, the stars, the sunrise and sunset, the moving light, the traffic, and even the flowers were all suitable for time-lapse photography. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
How Canon shoots time-lapse photography videos
There were a few things to pay attention to when shooting time-lapse videos with Canon: ** 1. Choice of camera ** If you were shooting at night or when the sun turned to night, you had to choose a camera with good dynamic range and long-exposure noise control performance, such as Canon's Eos R5 Mark II, which had a 45-million-pel full-frame LCD with excellent dynamic range and noise control performance. The interval shooting function on the camera was very important for time-lapse photography. It was best to shoot in RAW format and retain the mechanical shutter function (because the electronic shutter would cause brightness problems during time-lapse shooting). ** 2. The camera settings ** 1. ** Shooting format **: Try to choose the RAW format. It is recommended to use the RAW + JPG format. This is because only the RAW format can adjust the exposure, white balance, flicker removal, and other parameters when processing time-lapse photography materials in the later stages. JPG can only directly synthesize time-lapse materials and cannot adjust the materials. 2. ** Shutter Type **: Mechanical shutter. 3. ** Image Type **: Choose to use the combination of RAW and JPG. 4. ** Scene Shooting **: - First, the composition of the scene was done. The exposure was set according to the image. It was recommended to use the A file. The sensitivity should be as high as 100 to ensure the image quality. Then, the aperture size could be set according to the needs (for example, the aperture could be set to F5.6 - F8 for shooting scenery). The shutter speed could be automatically adjusted by the camera. - After setting the shooting parameters, he entered the menu and found the interval shooting function. He set the number of photos to be taken and the length of the interval between two photos. The two most important items in the interval menu were the number of shots and the interval time. To make the time-lapse video look smooth, a one-second video would need at least 24 photos (for example, if you want to take a 10-second time-lapse video, you would need to take 240 photos). Canon cameras also provided an "unlimited" option, which was suitable for users who needed to take a long time-lapse video or did not specify the length of the time-lapse video. In terms of the time interval, the general time interval for shooting scenes with clouds or heavy traffic during the day was 3s - 5s, the time interval for shooting the day turning to night was 10s-15s, and the time delay for shooting the starry sky was 15s-30s. It should be noted that if the light dimmed after dark and the exposure time increased beyond the interval time, it was necessary to set the interval time longer in advance or set the USB to a relatively high setting. In addition, the shooting delay was usually selected to be in M mode, with manual focus. It was also best to turn off the body's high-sensitivity noise reduction and the body's automatic dark part compensation (such as Canon's highlight priority mode) to reduce the possibility of lens shake caused by the internal calculation of the camera. If you use a single-lens reflex camera to take time-lapse photography, you also need to pay attention to: 1. If the camera did not have an interval shooting function, an external timer would be needed, and a programmed shutter release was a better choice. 2. When shooting, you may encounter the problem of the exposure time being too short. You can use the ND dimmer filter to slow down the shutter speed to achieve better results. 3. Since time-lapse photography required a stable shooting platform, the use of a tripod could ensure the stability of the fixed camera (if it was a large displacement delay, a slide rail might be needed). 4. Prepare sufficient backup batteries and memory cards. If conditions permit, it is best to connect to alternating current for filming. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Which mobile phone has a time-lapse photography function?
The document only mentioned that Huawei phones had time-lapse photography, but in fact, many brands of mobile phones had this function, such as the common Apple, Xiaomi, Samsung and other mobile phones. However, the document did not give specific evidence that other phones had this function, so it was impossible to know exactly which phones had this function. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Super shocking, beautiful starry sky time-lapse photography
Here are some key points about the stunning and beautiful starry time-lapse photography: ** 1. Initial preparations ** 1. ** Location Selection ** - They had to stay away from densely populated areas to reduce the impact of light pollution. For example, they could choose uninhabited environments such as grasslands, Gobi, deserts (such as the Taklamakan Desert), or drive more than ten kilometers away from the city to see the beautiful starry sky. - The starry sky was different in different locations. For example, in the northern hemisphere, places that were better for shooting the Milky Way and the starry sky were Shangri-La Balagezong Grand Canyon, Yunnan Dashanbao, Yunnan Wuding Jiyi Town, etc. 2. ** Time Planning ** - In terms of seasons, it was better to shoot the Milky Way and the starry sky in the northern hemisphere in spring and summer. The Milky Way could not be seen in the winter night sky, so the time to shoot the Milky Way every year was very precious. - The phase of the moon would also affect the shooting of the Milky Way. One had to use astronomical knowledge to check the effects of the moon in advance and choose the right time. - Check the sunrise, sunset, and starry sky schedules. You can use astronomical applications or websites to obtain the accurate rise and set times of the sun and stars. Plan the shooting time and make full use of the different light stages. 3. ** Check the weather ** - Check the weather forecast in advance to avoid cloudy or foggy weather and ensure that the sky is clear and clear. 4. ** Equipment preparation ** - ** Cameras **: Full-frame cameras can achieve better image quality while maintaining a high CPU value. For example, the Nikon D850 has an effective resolution of about 45.75 million, and the high-sensitivity image quality is excellent. - ** Lenses **: Large aperture wide-angle lenses are preferred, such as the Nikon Nikkor 14 - 24mm F.8G ED, with a 14mm focal length that can capture images of the starry sky with a view angle of more than 110 degrees, a constant maximum f/2.8 aperture to ensure the amount of light entering, and a 14 - 24mm zoom range to cope with more landscape photography scenes. - ** Tripod **: A stable tripod can keep the camera stable and get a clear and sharp picture. It can carry a shutter release to prevent vibrations from touching the camera and affecting the image quality. If he used a mobile phone to shoot, he could also use the time-lapse camera function that came with the mobile phone. He could also use the method of shooting the star trajectory at intervals to synthesize the special effect video of the starry sky. ** 2. Filming process ** 1. ** Setting of parameters ** - When shooting during the day, use a fast shutter speed and appropriate aperture to ensure that the image is bright and clear. Gradually adjust the parameters during the transition, reduce the shutter speed, increase the aperture to maintain the exposure balance, and may need to use a neutral density filter to reduce overexposed. Gradually reduce the effect of the filter during the transition to gradually increase the brightness of the photo at night. - When the day completely turned into night, switch to starry sky shooting mode, use a longer exposure time and an appropriate USB to capture the details of the stars, and use a wide-angle lens to capture more starry elements. - During the transition from day to night, the exposure parameters had to be continuously adjusted, and multiple checks and adjustments had to be made to ensure a smooth transition. If the star track was shot, a smaller aperture and a lower IQ had to be used to reduce noise and take a longer exposure. 2. ** Points to note ** - Batteries and Storage Space: Make sure the camera has a sufficient battery and enough storage space, especially when shooting for a long time. - Shockproof measures: The tripod must be stable. You can use the remote control or time-lapse shooting mode to prevent the camera from moving slightly. - Do not disturb mode: Do not use flash and equipment that affects the surrounding environment and the shooting effect when shooting at night. - Use the previewing function: Use the camera's real-time previewing function to check the exposure and composition during shooting, and adjust it in time to find problems. - A smooth transition: The transition between the sun and the night must be smooth. By adjusting the parameters and monitoring the brightness, it is necessary to avoid sudden changes in brightness. - Night Focus: Use manual focus or the camera's low-light auxiliary focus function to shoot stars at night to ensure accurate focus and clear stars. - Considering the shooting of the star orbit: If you want to shoot the star orbit, you need to take a long exposure, use a small aperture and a low IQ to reduce noise. - Time Division: If the shooting process is long, it can be shot at different time periods to reduce the difficulty. - Maintain safety: When shooting outdoors, you should bring along cold or heatstroke prevention equipment, inform others of your whereabouts to prevent accidents, and try to shoot from different angles and compositions. During the shooting process, you can save the data in time to prevent data loss. You can also learn the starry sky map to choose the appropriate composition and angle. ** 3. Post-processing ** 1. ** Uniform format and style ** - Shooting in the RAW format allows for more editing in the post-production. Post-processing to ensure that the entire time-lapse photography sequence uses a similar style to maintain compatibility, can use Lighthouse or other post-processing tools for batch processing. 2. ** Star Orbit Processing ** - If time-lapse photography includes star trajectories, use professional star trajectory software to make the star trajectories smoother and more natural. 3. ** export and share ** - It can export high-quality image files and create time-lapse videos to share or print. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
