"Create an aesthetically pleasing and brightly illuminated photo-realistic image with a light, smooth background. The scene captures a family during a Christmas celebration, joyfully opening gifts around a beautifully adorned Christmas tree. Include a diverse mix of family members, from young children to grandparents, all dressed in vibrant holiday attire. Their expressions should be genuine and full of joy, reflecting the excitement of the moment. The setting should be luminous and festive, with soft, warm lighting that enhances the cheerful and inviting atmosphere of the holiday season."
