What is time-lapse photography?

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's the difference between slow photography and time-lapse photography? In fact, there is not much comparability between these two photography methods.

Time-lapse photography, also known as time-lapse photography, is a shooting technique that compresses time. It takes a group of photos or videos, and then through photo stitching or video frame extraction, it compresses the process of minutes, hours or even days and years into a short period of time and plays it out in the form of video. In time-lapse photography video, the slow change process of an object or scene is compressed into a very short time, showing a strange and wonderful scene that is usually imperceptible to the naked eye. For example, playing the process of flowers blooming and falling for one minute is definitely not a minute.

Slow photography is shooting with a slow shutter. For example, sometimes taking pictures in dark light can make people paste. It is because of insufficient light that the shutter speed slows down to ensure exposure. If it is slow, the photographer's hand will shake and paste the photo. Therefore, it is best to use a tripod for slow photography. When it is used to shoot running water, it will form a satin-like effect, as shown below.

In fact, time-lapse photography and high-speed photography can be compared and understood. High-speed photography is to shoot fast-moving objects with high-speed cameras, and then play them out in slow motion. For example, shooting a bullet out of a gun chamber is a typical high-speed photography.

Question 3: 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: 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 5: What is time-lapse photography? Is to shoot a straight light in the traffic.

Question 6: How can time-lapse photography produce three practical effects? Explain the use of camera slow exposure B door.

Gate B is a photography mode that can be said to be beyond the four camera modes (A, S, M, P) and can also be regarded as an extension of M-file. In B-door mode, the photographer can adjust the aperture and completely control the shutter speed, which is very different from M-file. Generally speaking, the photographer can freely adjust the shutter speed within the range of m 1/8000 seconds to 30 seconds. On the other hand, when the photographer presses the shutter button, the door B will be opened, and when the shutter button is released, the door B will be closed. What are the advantages of doing so? Let's look at some photos and learn how to use door B from actual combat.

Actual effect 1: calm water surface

Rare mirror surface.

Why is it so hard to do it?

I believe that if you look for a mirror-calm water surface all over the world, you can still find it, but you should know that most lakes and seas are rough.

What scene is it suitable for?

A scene with dim ambient light.

What should I do?

Fix the camera with a tripod. Then turn the camera to gate B. Some cameras have a separate B-door mode in the mode dial, and some cameras adjust the shutter speed to B-door after 30 seconds in M-file. Use a smaller aperture after turning to door B. At this time, it is best to use the cable release to operate the camera shutter, otherwise the shutter button will be pressed all the time. Even if you ignore the camera shake, your hands will be sore if you press it for a long time. Press the shutter button on the shutter line to lock the shutter. Then wait two or three minutes for a short time and half an hour for a long time to see the brightness of the ambient light. So it is necessary to take more photos. When you feel that the exposure is almost complete, you can unlock the shutter button and the exposure is complete.

Why can this effect be produced?

Even if there are small waves on the water surface, these waves are within a certain range. Long exposure can ensure that waves appear at every position on the water surface. It is equivalent to smoothing the uneven water surface. Man in the mirror naturally came out.

Actual effect 2: stellar orbit effect

What is this?

Beautiful track effect.

Why is it so hard to do it?

Looking up at the sky, we can only see a few stars. If a star is dragged out of orbit, it will take a long time to be exposed.

What scene is it suitable for?

Scenes with very dim ambient light. It doesn't matter even if there is no light around.

What should I do?

Fix the camera with a tripod, then adjust the camera to door B and adjust an appropriate aperture. If it is not too small, the orbit of the star will be very thin. After that, B-gate exposure is performed. If you want to get a shorter orbit, you can expose it for about 15 minutes. If you want a complete Sunday exercise, you can expose 10 for several hours. However, it should be noted that if a digital camera is used, the sensor of the camera will emit a lot of heat, followed by increasing noise, and the sensor may overheat and burn out. So I suggest you use CMOS digital camera as a sensor to shoot. CCD generates a lot of heat, so it is easy to be burned.

Why can this effect be produced?

The stars in the sky did not move. Even if the stars actually move very fast, we can't feel anything beyond n light years. This effect is entirely due to the rotation of the earth, so the orbits of the stars are concentric circles. In the northern hemisphere, the center of this concentric circle is basically Polaris.

In addition, if a meteor appears at this time, a straight bright line will appear on the concentric orbit. The so-called meteor photography also uses this method. As an author who has worked hard for the cause of astronomy in China for several years, I am familiar with this.

Actual effect 3: Motion trajectory

A continuously recorded trajectory.

Why is it so hard to do it?

The same person completes the effect of similar multiple exposures in the same scene. If you really use multiple exposures, it is difficult to achieve this effect.

What scene is it suitable for?

A scene without any ambient light.

What should I do?

Fix the camera with a tripod, then adjust the camera to door B, and adjust an appropriate aperture, which should match the flash index and shooting distance. The specific formula is flash index = aperture × distance. Then adjust the flash to strobe state according to the flash index. Press and lock the shutter, and then the photographer can give a password to let the model start moving, and at the same time let the flash start flashing. After the action is completed, stop the stroboscopic state of the flash, and then release the shutter button to end the exposure.

Question 7: What's the difference between slow door and time-lapse photography? Slow door and time-lapse photography are two completely different shooting methods.

Slow doors refer to splashing water, waterfalls, floating clouds, light tracks, etc. Has a relatively slow shutter speed.

Time-lapse photography, also known as interval photography and micro-speed photography, refers to taking multiple photos at a certain interval and then synthesizing the video.

Question 8: What is time-lapse photography? That is, when you are shooting, something is turning around the underground shooting button, and one turn is equal to one second of reality. Generally speaking, it is to exert influence quickly, and it can shoot the rise and fall of the sun, which can speed up the speed and facilitate observation. Thank you for your adoption.

Question 9: Time-lapse photography. Time-lapse camera Time lapse photography. Delayed shooting. What's the difference between the four? Time-lapse photography-using video recording, the interval shooting time and the duration of each shooting can be adjusted, such as recording for 5 seconds every 30 minutes;

Time-lapse photography-as mentioned above, the shutter is only opened once, and the interval and shutter speed can be adjusted;

Time-lapse photography-this function is rarely used. Now many cameras are basically gone. It is only used in security monitoring, such as turning on infrared sensing. When an object is in the infrared range, the camera begins to record;

Time-delayed shooting-that is, the * * * mode on the camera is generally adjustable from 2 seconds to 10 second.
