SLR time-lapse photography skills

Time-lapse photography is a photography technique that takes an image or video at a low frame rate and then plays the image at a normal or faster rate. 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. The following is the relevant information about SLR time-lapse photography skills that I have compiled for you for your reference!

SLR time-lapse photography skill one,

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, medium screen size.

* 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, be sure to pay attention to the need to cut the upper and lower parts of the picture).

note:

* Don't raise the central axis of the tripod to ensure stability;

* Use a medium telephoto lens (above 50mm) to ensure the stability of the tripod;

* When shooting, add an eyepiece cover to prevent the incident light from affecting the photo exposure (if not, you can 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.

3. Post-processing

Import photos from the memory card into the computer, and there is a folder for photos of each scene.

(1)PS batch processing

Use this step to adjust the tone of the final video, which is suitable for both color and black and white. Because of the large adjustment space and many details, PS is used instead of ordinary video editing software.

Recording actions, necessary steps in recording:

* Sharpen: Use the USM that comes with PS to sharpen it. As the case may be, don't exaggerate;

* Cropping: Cropping pixels to 2048? 1 152;

Set the ratio to 16:9. Why is this value? Because the maximum width of video clips that audio and video can save is 2048 pixels.

Some plug-ins support action batch processing, such as color efex and silver efex of nik software, but pay attention to the use of layers, and users who use plug-ins for slow batch processing and low configuration should be cautious.

Open the PS menu after recording the action? Documents? Automatic? Batch processing: Select action, target folder and output folder to start batch processing.

(2) Post video

Classify and manage the folders of processed pictures.

Composing UIS image sequence for editing:

Turn on audio and video X4.

Open the file? Insert media files into the timeline? Insert photos with delay/flash applied, select folders, select all or more photos, and then confirm.

SLR Time-lapse Photography Skills II,

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 color filter is used to adjust the color of the main body; The other is the canopy mirror, which is used to adjust the spot shape.

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. Stability is overwhelming. Be sure to fix the camera firmly on a solid tripod to avoid the camera shaking due to wind and other reasons, which will lead to shooting failure.

Prepare enough spare batteries and memory cards. Time-lapse shooting usually takes several hours or even dozens of hours, so it is necessary to prepare enough accessories according to the length of the required material. If conditions permit, it is best to turn on the alternating current to shoot.

Fuselage setting

M gear, ISO manual. Normally, the aperture should not be too small. Although a small aperture can bring a large depth of field, it will also bring dust marks on the lens and CCD and diffraction of light. F8 is a suitable breakthrough. White balance is manual, which can be preset or adjusted manually. 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, the maximum light change can reach 3EV within 30 minutes in winter, so please adjust the exposure appropriately.
