How did the iPhone make those light drawings?

At least two friends can cooperate with each other to finish it, so it is more varied and more interesting. Light painting photography can be done indoors, at night, or even in some dim light environment where it is completely impossible to take pictures. It doesn't need a special camera or lens, and almost everyone can take pictures. Light graffiti preparation:

1, it takes two people, one to take pictures and the other to draw patterns with light;

2. Prepare flashlights, cameras and tripods. If you don't have a flashlight, you can change it to a mobile phone screen. If you don't have a tripod, you can also put the camera on a stool, table or railing.

Light graffiti photography skills:

1, take out the props above where you can't see your fingers;

2. Set the camera to M, and select manual as the focus mode;

3. Adjust the sensitivity to ISO 100, the shutter speed to a few seconds, and the aperture is about 8;

4. The photographer presses the shutter, and another friend is opposite the camera, drawing any pattern you want in the air with a flashlight;

5. Look at the photos! If the photo is too bright, reduce the aperture, if it is too dark, enlarge the aperture and try again!
