In the park, why do you record videos for others with your mobile phone in the afternoon, and you can also take your own shadow? Is it because the sun is shining?

When recording video for others with a mobile phone, it is usually the front light, not the back light. Therefore, when the sun is shining, your position is just between the sun and the subject, not only in the afternoon, but also in the morning. When the sun is not high, the shadow is long. If you are close to the recording, you can bring your own shadow in without paying attention, and you can avoid it with a little attention.
