Light skills in children's photography

There are several important points to keep in mind about the position of the main light: when the position of the light source is higher than or approximately parallel to the position of the subject's nose, the light source should be close to the head, and the shadow will fall on some parts of the nose, chin and eye socket; Eyelashes even cast a faint shadow on the eyes, which requires some auxiliary light to illuminate these shadows and make the eyes glow again.

When you lower the light source and open it, your face is obviously "changed" and more shadows can be clearly seen on the other side of your face. Most people like photographers follow a general rule: place the main light at the camera/subject angle of about 30 to 45, and the height is moderate.

Vision: Vision is a tiny (pure white) reflection of iris reflection of eyes, which makes eyes look vivid; Without the light of eyes, the subject looks blank and dull. The eye light you shoot will be the same as the main light you use-if you use a soft box, the eye light will be square; If a grid lamp is used, the eye lamp will be long or rectangular, and so on. If you add light to your eyes with a second lamp or reflector, they will all be reflected into your eyes, and this "second eye" can be treated more naturally after shooting.
