Before shooting video, we need to prepare light sources such as mobile phones and flashlights, and then fix the mobile phones with mobile phone brackets or something, so as to continue the next step.

Generally speaking, the distance between the lamp and the wall is 1-2 meters. When people stand in front of the light and shoot shadows, the size of the shadows can be adjusted by the distance.

After that, users can use the front camera of the mobile phone to shoot their own shadows projected on the wall, and interested friends can come and have a try!
