Focusing on natural grooming rather than heavy styling often yields the best results for this age group:
Backlighting a subject against a darker background can create a "rim light" effect that defines their silhouette.
Use prompts to get genuine reactions, such as asking them to "fake laugh" (which often leads to real laughter) or imagine their favorite place.
If using makeup, focus on enhancing natural features or covering small blemishes with concealer rather than heavy application.
Encouraging them to walk toward or away from the camera helps capture authentic expressions. A popular technique is having them walk away and look back over their shoulder.
Sitting on the ground or leaning against walls, fences, or trees naturally shifts their weight, preventing a "stiff" or rigid appearance.
Shooting from slightly above during sitting poses can define the jawline and capture "catchlights" in the eyes.
