When is the best time to take pictures in a day?

From 8: 00 a.m. to 8: 00 p.m. 10 p.m. and from 3: 00 p.m. to 5: 00 p.m., because the light height in this period is just around 45 degrees, and 45 degrees is the "usual height" often used in lighting, people usually look full of vitality and sunshine after finding their faces, and their faces will look good.
