What do you mean by time-lapse shooting?

Question 1: What is time-lapse photography? Long-time freeze time delay shooting. Also known as low-speed photography or fixed-time photography, "time-shrinking" photography. A means to record and reproduce the slow changing process of the scene with obvious changing images at regular intervals. For example, it takes about 3 days and 3 nights for a bud to bloom, which is 72 hours. Shoot one frame of it every half hour, record the subtle changes of flowering action in turn, shoot 144 frame at * * *, then show it with a projector at normal frequency (24 frames per second), and reproduce the flowering process for 3 days and 3 nights within 6 seconds.

Question 2: What is time-lapse photography? How to shoot? time-lapse photography

Also known as time-lapse photography (English: time-lap photography), it is a shooting technique that compresses time. It takes a group of photos, or later, it compresses the process of minutes, hours or even days and years into a short time, and plays it in a new way by connecting photos or extracting frames. In a period of time-lapse photography, the slow change process of an object or scene is compressed in a very short time, showing a strange and wonderful scene that is usually imperceptible to the naked eye. Time-lapse photography can be regarded as the opposite of high-speed photography. Time-lapse photography is usually used to shoot urban scenery, natural scenery, astronomical phenomena, urban life, architectural manufacturing, biological evolution and other topics.

To put it bluntly, most of what you usually see in astronomical documentaries is taken by time-lapse photography. Like some arc-shaped star orbits or something, simply put, the shutter is very slow. One of your documentaries, the scenery of time. Very good.

Question 3: Time-lapse video, slow video in the camera, what is it? What does this mean? Time-lapse photography is essentially photography, and the pictures are all high-resolution. You can compress the connection, that is, fast forward the video. Ordinary video is 24 frames per second. The resolution of each frame is relatively small, usually 8 million pixels is a lot.

Question 4: What is time-lapse photography? Friends who have used digital cameras may have a feeling that it will take a short time to continue taking the next picture after pressing the shutter. So what is the reason for this phenomenon? In fact, for today's digital cameras, there will be this phenomenon-shooting delay. The so-called "shooting delay" means that it takes some time to shoot the second picture after shooting the first picture. This does not exist in traditional cameras, but almost all digital cameras have this interval, and some models even have a delay between pressing the shutter and the real action of the camera. Due to the delay of digital camera shooting, not all digital cameras are suitable for fast continuous shooting at present. So what is the reason for the delay in this shooting? It turns out that after pressing the shutter, it takes a few seconds for the camera to internally process, generate an image, compress it, then save the image in the memory, the CCD clears the charge, and finally reset the camera internally. That is to say, the shooting of a digital camera has gone through the process of "optical signal → analog electric signal → digital electric signal → recording on a storage medium", which requires time for conversion and recording, especially recording. Because the storage buffer in digital cameras is relatively small, the continuous shooting speed of all digital cameras is not very fast at present. After all the work is finished, you can take the next photo. But with the increase of camera memory and the improvement of compression technology, this delay will become shorter and shorter. Although many digital cameras provide continuous shooting function, some digital cameras support high-speed continuous shooting, and you can take several pictures of continuous shooting at a time. But you can easily notice that in ordinary digital cameras, most of them can only take low-resolution photos of continuous shooting, because the data of high-resolution photos is very large, and it will definitely take some time to process them. The shooting delay time of different types of digital cameras ranges from a fraction of a second to several seconds or even more than ten seconds. Of course, in order not to miss the shooting opportunity, the shorter the delay, the faster the response, the better. Moreover, the continuous shooting data provided by some manufacturers can't be achieved in actual operation. You should use it yourself and feel the delay time ―― you must use the same resolution. This is the best way.

Question 5: What does time-lapse photography simply mean? Simply put, take a photo at regular intervals, such as every minute, or every two minutes, and so on.

It is often used to shoot videos of plant growth, for example, every other minute, and 24 videos a minute when making videos, so you can see the process of plant growth. There are many such scenes in the documentary.

Question: What does iPhone time-lapse photography mean? The so-called time-lapse photography is faster than normal playback when shooting. When playing normally, the whole video will be watched at a slower speed, which will have unexpected effects.

Thank you. Please adopt it.

Question 7: What do you mean by taking pictures in time delay? When you press the camera button, it will avoid shutter jitter and choose the best picture from the past 1 second. But judging from our actual photo performance, it is true that when we take pictures with both hands or one hand, we can all feel trembling. If we take photos with ordinary mobile phones, if the optimization is not good, we can really see the loss of details after the photos are enlarged.

Question 8: What is delayed photography? It means fast play. Find a place with good scenery, provided there are clouds, or the starry sky is similar to a moving body that can't be observed by human eyes. Take an angle for a long time, improve the playback speed on the computer later, and add some color adjustment later.

Of course, the specific implementation may not be so easy, but it should be this idea.

Question 9: What is the function of time-lapse photography with mobile phone camera? Time-lapse photography is similar to frame-by-frame photography in film photography, also known as low-speed photography, timing photography and "time-shrinking" photography. It is a means of recording regularly and reproducing the slow changing process of the scene with obvious changing images.

Objects suitable for time-lapse shooting should have the following characteristics:

Time-lapse photography-the right theme

Objects suitable for time-lapse shooting should have the following characteristics:

There are obvious changes in the form and content of the theme (such as flowers blooming and falling);

The light effect and shadow of the subject have obvious changes;

The color, color temperature and brightness of the subject have obvious changes. [ 1]

Time-lapse photographic equipment

Low-noise full HD digital camera or digital camera with time-delay shooting function, stable tripod, spare battery, spare tape or memory card, watch, small flashlight (headlights are better), and electronic equipment with time-delay setting. [ 1]

Time-lapse photography-shooting skills

Use the time-lapse shooting function in the camera menu. Many high-definition cameras and home DVs have this function. Please read the instructions carefully and master the usage before use.

The effect of time-delay shooting can also be achieved by using a camera without time-delay shooting function-shooting according to normal settings, and extracting frames during post-production to achieve the effect of time-delay shooting.

Use the short film function of digital camera, such as Canon 5DII, with time-delay shooting function.

Take photos with a digital camera and synthesize short films through software. The camera takes digital photos every certain time (for example, 10 second, 30 seconds to several minutes and hours), and finally synthesizes them into a single frame scene in the post-editing software to achieve the effect of delayed shooting. If you shoot in this way, you'd better buy a camera delay controller, set the interval of delay shooting, and the camera will shoot automatically. However, it should be noted that due to the large format and resolution of photos, in order to save memory card space and facilitate later editing, it is best to use a small format in the camera to shoot. [ 1]

Determine the time interval

The determination of the time interval of delayed shooting directly affects the final shooting effect. First of all, three factors should be made clear: the final picture speed effect, the lens length and the shooting time span, in order to decide the time interval of delayed shooting. Do more experiments: the flow of clouds, the traffic at night, the shadow of the sun and the pedestrians on the street can help you find the time interval setting that adapts to different effects as soon as possible. [ 1]

Recommended time

Fast moving clouds on windy days: 1-2 seconds

Slow cloud: 5- 10 second

The shadow of the sun moving on the ground: 10-20 seconds

The track of the sun on a clear day: 20-30 seconds.

The state of the stars running in the sky: 10-60 seconds.

Close-up of the sun at sunset: 1-2 seconds

Crowd in the city: 1-2 seconds

Plant growth status: 5-40 minutes.

Time-lapse photography-precautions

Stability is overwhelming. Be sure to fix the camera firmly on a solid tripod to avoid camera shaking due to wind and other reasons, which will lead to shooting failure.

Avoid unnecessary sundries from entering the screen. If shooting on the road, in order to prevent pedestrians from entering the picture, the camera must be placed away from the sidewalk.

Prepare enough spare batteries and memory cards. Time-lapse shooting usually takes several hours or even dozens of hours, so you must prepare enough accessories according to the length of the required material. If conditions permit, it is best to turn on the alternating current to shoot.

Pay attention to the protection of machines. Because it takes a long time, in order to protect the safety of the camera and avoid the damage caused by natural and human factors, we must pay attention to taking good care of the camera when shooting in time delay, and avoid exposure and low temperature.
