Equipment selection of time-lapse photography

Time-lapse photography is also called time-lapse video. It is a kind of time-compressed shooting technology, which is also called time-reduced video at present. 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. So what are the equipment choices for time-lapse photography? Come and have a look with me!

The equipment of time-lapse photography and the advantages and disadvantages of SLR time-lapse photography

equipment

Main equipment: camera, tripod

Auxiliary equipment: timing pay-off, delay tracking, lens filter, equatorial plane, etc.

Shooting machine: Time-lapse photography is actually a necessary way of photography, so all photographic equipment that can take photos or videos can take time-lapse photography. Generally, in order to achieve better image effects, time-lapse photography is mainly based on SLR cameras.

Timing cable release: When shooting time-lapse photography with a SLR camera, it is necessary to take a series of photos at equal intervals, and it is impossible to completely press the shutter by hand. Many cameras have no interval shooting function and need an external timer.

Delay track: A photographic track equipped with a stepping motor and shutter controller. Through precise electronic and mechanical control, the camera moves a certain distance on the track every time it takes a photo, so as to achieve the purpose of moving shooting. Time-delay tracking is a professional time-delay shooting equipment.

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

Lens filter: there are three main types: one is ND mirror, which is used to filter light and reduce the amount of light entering the lens; The second is a dichroic mirror, which is used to adjust the color of the subject; The other is the canopy mirror, which is used to adjust the spot shape.

Equatorial instrument: professional time-lapse photography accessories, used to shoot stars. When shooting the starry sky, you can shoot the effect of the sky turning.

Advantages and disadvantages of SLR delay

superiority

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 time interval of camera shooting. 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.
