Shooting, actually I want to ask, is time-lapse photography the same as slow motion?

Time-lapse photography is a quick action, so speak quickly.

Slow motion means slowing down.

Time-lapse photography takes a long time to take a certain number of photos, and then plays them at the normal frame rate, so that a longer video can be played in a shorter time. On the contrary, slow motion takes a few more frames than the normal playback rate in normal time, and then plays them at the normal frame rate, so that the video can show short-term content for a longer time.

For example, if the normal speed of video playback and shooting is 30 frames per second, the video will be shot every five seconds. This delayed video is equivalent to playing the shot content of 150 seconds in one second, and the slow motion is shooting 120 frames per second, so it takes four seconds to play the shot content in one second.

Advantages of time-lapse photography

1, digital SLR can shoot large-resolution images. At present, the resolution of high-definition video is 1920x 1080, which is more than 2 million pixels. At present, the pixels of mainstream digital SLR are all above10 million, and the full-frame machine even reaches 20 million to 30 million. High pixels greatly improve the quality of delayed video, far exceeding many professional cameras.

At the same time, high pixels also leave a considerable space for post-processing, which is easy to produce the effect of pushing, pulling and translating the picture.

You can shoot in RAW format. RAW file retains the information and dynamic range of many pictures, and has greater color tolerance, which provides greater convenience for later video color correction.

You can master the exposure process completely. Aperture, shutter, ISO and white balance are all controllable.

4. You can check the photos taken at any time and control the shooting process and effect.

Disadvantaged

The file size of 1. has both advantages and disadvantages. High-resolution image files and RAW files will limit the camera shooting interval. The cache of different cameras is different. Too large a file will affect the processing speed of the camera. Once the processing speed can't keep up, the camera will stop shooting.

So sometimes we can only give up shooting RAW and use JPG format or even small resolution JPG format to get a shorter shooting time interval.

2. When shooting with a digital SLR, it is inevitable to encounter the problem of video flicker. No matter how careful you are, there is a certain probability that you will encounter this phenomenon, especially in the environment where the light changes greatly. This brings some problems to the later stage.
