What is time-lapse photography? Time lapse photography experience.

What is time-lapse photography? In fact, for digital cameras, will this happen? Shooting delay. So-called? Shooting delay? That is, after taking the first picture, it will take some time to take the second picture. This does not exist in traditional cameras, but almost all digital cameras have this interval, and some models even have a delay between pressing the shutter and the real action of the camera. Because of the delay of digital camera shooting, not all digital cameras are suitable for fast continuous shooting in this case. Time-lapse photography is often used to photograph many natural subjects, such as cell division, egg hatching, solar eclipse, cloud change, astronomy, geography, urban change, urban life, traffic and so on, in order to accumulate scientific research data. Next, let's take a look at the time-lapse photography experience shared by photographers.

1, preliminary preparation

Equipment: timing cable releaser, tripod, filter (as appropriate). The camera lens comes with it, and the memory card is better than 8G, and 4G is also acceptable.

Software: Photoshop, audio-visual studio X4(Corel VideoStudio Pro X4), preferably X4 version, with the function of importing delayed image sequences.

2. Shooting method

(1) fuselage settings

M gear, ISO manual.

Note: except for special circumstances, such as the single subway scene (which does not affect the metering system), the light changes greatly, so I use automatic ISO200? ISO 1600 .

White balance is manual, which can be preset or adjusted manually.

JPG straight out, color, 1000W pixel model, choose the highest quality, and the picture size is medium.

Turn off the high-sensitivity noise reduction of the fuselage and turn off the automatic dark compensation of the fuselage (Nikon's D-lighting, Canon's highlight priority mode, Sony and Pentax's automatic HDR).

Note: In the evening and at sunrise, the light changes greatly. According to experience, within 30 minutes in winter, the maximum change of light can reach 2~3EV, so please adjust the exposure appropriately.

(2) Cable release settings

Just set the INTVL option (Yongnuo MC-36b), that is, the interval between each shooting.

1) When shooting the traffic and pedestrians in the city during the day, the interval time is set to 1 sec, and the shutter speed of the fuselage is set within 1 sec.

2) When shooting urban night traffic, the interval is set to 2 seconds to 5 seconds, and the shutter speed of the fuselage is set to interval minus 1. (Example: the interval is 3 seconds, and the shutter speed of the fuselage is 2 seconds)

3) When shooting the movement of clouds in the sky, set the interval time to 3 seconds to 10 second according to the movement speed of clouds. The slower the cloud moves, the longer the interval.

(3) Shooting process

The tripod fixes the camera and the view: predict the position (since the aspect ratio of the later video clip is 16: 9, it must be noted that the upper and lower parts of the picture need to be cropped).

note:

Do not raise the central axis of the tripod to ensure stability;

When using a medium telephoto lens (above 50mm), ensure that the tripod is stable;

When shooting, add an eyepiece cover to prevent the incident light from affecting the photo exposure (if not, cover the viewfinder with dark clothes or cloth and fix it).

(4) Determine the shooting time.

Shooting duration (minutes) = interval shooting time (seconds)? 24? How long do you want the clip to last (in seconds)? 60;

Number of lenses =24? Length of the final required segment (seconds);

Example: Finally, I want a 20-second delayed video clip with an interval of 3 seconds, so the shooting time is:

3? 24? 20? 60=24 (minutes), and the number of shots is 20? 24=480 sheets;

Note: generally shoot as much as possible. If you need a clip of 10 second, it is best that the original clip is from 15 second to 20 second, leaving room for the later transition of the video.
