How is the sunlight effect in the photo taken?

I don't see any special effect of sunlight in your photos, but there is a bad "glare", the light on the model's right eye. Fifteen, glare camera lens is composed of many individual glass lenses installed together, these individual glass lenses are called lens units. When bright light passes through camera lenses, part of the light will be reflected by the surfaces of these lens units. This kind of internal reflection will create an illusion, which will appear like an image in the final photo, as shown in the upper right corner of the lower left picture. The glare that appears near the top center of the picture on the right is like a small heptagon. Glare removal method: The usual practice is to install a hood on the lens. If the light is just at the edge of the image, the hood will eliminate this glare. However, if the strong light is right in front, the range hood can do nothing. Try to adjust the aiming direction of the lens and find the shooting direction that can eliminate glare. If the subject does not allow the camera to move or rotate, try to block the light source and block the direction of the light source with your hand (or hat or cardboard) at a certain position in front of the camera. In fact, this is equivalent to using an extended range hood.
