"Create a photo-realistic image with a smooth, solid-colored background to emphasize elegance and simplicity. Feature a baby dressed in a traditional white christening gown, including a cap on its head, held by its parents who are dressed for the occasion. The father is in a dark, formal suit, and the mother in a sophisticated, light-colored dress. One of the parents is holding a small, beautifully wrapped gift. All three are smiling gently, conveying the warmth and joy of the baptism. The image should capture a half-body shot of the family, focusing on their serene expressions and the meaningful details of the event."
