When is the best light when shooting outdoors?

Last time I listened to the professor, I said I wouldn't take pictures at noon! The light depends on the weather and what you shoot! In addition, side light: the paraxial axis of the lens is 90 degrees from the light source, which is the most personalized. The light source and lens are 15 degrees, which is most suitable for taking scenery! In the morning, the outdoor portrait should be 15 degrees, and the light is hard. Shoot when there are clouds! This is not fixed, only personal experience. Yuntaing.photo.pconline.com.cn is our classroom, the photo moderator of Pacific Computer Network, you can go and have a look!
