How to set a time-delay photo?

First, turn off all automatic functions:

1. Turn off the "automatic shutdown" function to prevent the camera from automatically shutting down and affecting shooting.

2. Turn off the image preview function. During the shooting, the LCD is always off, which can save a lot of electricity.

3. Turn off the autofocus on the lens (that is, focus manually with MF). When turned off, the lens will not focus back and forth when shooting.

4. Turn off the anti-shake function. If it is slow photography, the automatic anti-shake of the lens is likely to make the image very blurred.

Second, make sure that the card capacity is sufficient before each shooting:

It is recommended to format the card before each shooting, so as to ensure that the files on the card will not be confused with each other and the shooting will be more organized. When choosing a memory card, try to buy a high-speed card with large capacity, otherwise you may encounter insufficient card capacity or miss a wonderful shooting opportunity, or the card speed is too slow to record shooting data continuously.

Third, the shooting format uses RAW format images:

Although JPEG format takes up less memory and is easy to handle, the post-editing space of RAW format is much larger than JPEG format, especially when the highlight overflows when shooting clouds, you can edit and restore the dark data later. When shooting in JPEG format, you must avoid using "automatic white balance", which will cause slight deviation and adversely affect the shooting effect. If you use the RAW format when shooting, these can be left to the later stage, so the RAW format is the correct choice and the necessary format for shooting time-lapse photography.

Fourthly, set ISO, aperture and shutter speed to realize "digital negative":

Many decisions need to be made when setting these parameters, such as aperture. Using a small aperture value can get a great depth of field, which is very clear from the foreground to the background, especially in an open scene. There is also the shutter speed, sometimes the shutter needs to be fast enough to avoid camera jitter or motion blur. Digital negative is a kind of information-rich image, which avoids the overflow of highlights and dark parts, which means that there is a lot of room for post-processing.

5. Protect highlights when shooting:

The principle of digital photography is: always protect the highlights. Whenever the highlight or cloud in the photo overflows, it will not be transferred back, because that part of information has been lost, so when you don't know how to expose it, make sure it is always in an "underexposed" state, or darken the image as a whole to protect the bright area. Today's cameras have the function of "highlight overflow warning". When playing back the photo, find the flashing area in the image and warn it to overflow.
