How to play time-lapse photography?

Nowadays, photographers especially like to play a kind of photography when shooting night scenes, that is, time-lapse photography.

Do you know what time-lapse photography is? Can it only be played by camera? What should I pay attention to when playing time-lapse photography? Today, I will talk to you about these issues.

Time-lapse photography, also called time-lapse photography and time-lapse video recording, is a kind of shooting technique to compress time, and it is also called time-lapse video recording at present. It takes a group of photos or short videos, and then it compresses the process of minutes, hours or even days or years into a short period of time through photo stitching or video frame extraction, and plays it in the form of video. In time-lapse photography video, the slow change of an object or scene is compressed in a very short time, presenting 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.

? In addition to the camera, the mobile phone also has this function.

Requirements for time-lapse photographic equipment

When playing time-lapse photography, you usually need to use a camera or mobile phone, tripod, timing pay-off, lens filter, etc.

Here I will also break down the main functions of these devices.

1, camera or mobile phone

Time-lapse photography is actually a necessary way of photography, and all photographic equipment that can take pictures or videos can take time-lapse photography. Generally, in order to achieve better image effects, time-lapse photography is mainly based on SLR cameras. Now, with the improvement of the photography function of smart phones, many friends begin to play time-lapse photography with their mobile phones more.

2. Release the timing cable

Time-lapse photography with a SLR camera needs to take a series of photos at equal intervals, so it is impossible to completely press the shutter by hand. Many cameras have no interval shooting function and need an external timer.

Step 3: tripod

The shooting of time-lapse photography needs a stable shooting platform, and any shaking will lead to the shaking and jitter of the later video images. The tripod can ensure the stability of the shooting picture. For a wide range of displacement delay, tripod is essential.

4. Lens filter

There are two main types in common use, one is nd mirror, which is used to filter light and reduce the amount of light entering the lens; The second type is a polarizer, which is used to eliminate the reflection of the subject and make the color saturation higher and more realistic.

SLR time-lapse photography

Today, taking SLR as an example, let's briefly talk about how to play time-lapse photography.

As I mentioned before, time-lapse photography is actually a photography method that takes a group of photos or short videos, and then 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.

Usually, I like to set 25 photos a second, and the camera is set to pure manual mode, M range, shutter speed manual, aperture manual and white balance manual adjustment (this is very important. Once set, you can't move once you beat it.

The shutter depends on what you shoot. If a scene takes several hours, just calculate the interval of 320 beats by yourself.

Note that the camera can be used with its own time-delay shooting function (Nikon's), and there is no need to buy a CNC cable to release it. However, the time calculation of Nikon's delayed shutter function includes the shutter time, that is, if the shutter speed is 3 seconds and the interval between you is 2 seconds, the interval should be adjusted to 5 seconds, and the number of shots is limited. It is still recommended that shi'yo use the timing cable to release.

Post-synthesis, just use general video software. I prefer to use Pr to import and output a complete video, and then make post-adjustment, brightness and color, displacement and so on.
