Time-lapse photographic synthesis technology

Next, I will teach you how to make time-lapse photographic film with the photos taken back. The software used is Photoshop CS6. The following describes the specific process according to the author's experience:

First, the classification of photos

We want to make a movie with 1080p 25fps, that is, a full HD movie with 25 frames in one second. The length of the movie is 4 seconds, and we need 100 photos. You must know how to calculate the number of photos you need according to the time you want to play. Therefore, a time-lapse photography scene often uses one hundred to hundreds of photos. In order to facilitate time-lapse photography of different scenes, each scene should be placed in a different folder.

Second, check the photos.

When previewing the picture, you can look at the abnormal picture in the middle. What is an abnormal photo? For example, on the way to time-lapse photography, a passerby suddenly walked in front of the camera and a black shadow appeared. If you don't want that shadow to appear in the finished product, delete the relevant photos. If only 1-2 photos are deleted, it will have little impact. However, if there are too many photos involved, ticket skipping may occur. Therefore, everyone should try to avoid any accidents during the filming process. Of course, if you shoot a fixed scene, you can also artificially create some episodes to make the photos look different. But the fixed scene can't be changed at will.

Third, after the photos are taken back, they should be compressed in batches. I'm used to batch processing with light and shadow magicians, so video files don't take up much space. In order to prevent confusion, it can be numbered according to the shooting time.

Fourth, the late synthesis process:

1. open PS? File-Script-Load File to Stack-Browse to Open File Select All-OK

2. Click on the window? Timeline-To create a video timeline, click the three small square buttons in the lower left corner to convert them into video frame animation.

3. Press the button in the upper right corner of the timeline? Create a frame from a layer? Select all frames, and then select reverse frames. These pictures are arranged in order.

4. The time loop is played forever, and the interval is selected according to the scene. Click Play to see the effect. The host can add background music, etc.

5 .. documents? Exit? Render the video? High quality? Click Render.

6. Save in WEB format. Save it as a GIF file.

Tip:

1. A mature time-lapse photography requires not only photography skills, but also strong post-production ability. Excellent editing and a special effect will bring different effects to the film. Making dynamic pictures is relatively simple. After a few steps like this, a simple GIF is ready, just like the animation above.

2. Time interval control during intermittent shooting. Generally, wireless timing remote control is used to shoot, and it is set appropriately according to the change of shooting object, mainly depending on the length of exposure time.

3. Select the number and size of photos. Smooth images are generally 25 frames per second, which means that 25 photos are one second. You can calculate the number of shots according to the length of the video you finally want. As for the size, because the later works are all movies or animations, I personally suggest that there is no need to use a larger screen to reduce unnecessary space occupation.

4. Focus setting when shooting. Due to the need of some time, the shooting interval is short. At this time, it is necessary to switch to real-time photography and manual focusing mode to reduce the shooting time caused by focusing longer than the shooting interval.

5. The synthesis of stellar orbits can be referenced, and there are also special applications of stellar orbit synthesis software. All the year round, every moment, the life of a person or a family can be expressed in this way, only you can't think of it, and you can't do it without you.
