A full-length portrait of two children, a girl and a boy, standing in a stylized Christmas winter setting. The girl leans on a red wooden stool, and the boy rests his hand on it, both looking at the camera. The girl wears a white, floor-length tulle dress with ruffled cap sleeves. The boy wears a red suit with a vest and trousers, a white shirt, and brown shoes. The background is a photo studio with decorations: a white house facade with large window panels, two large snow-covered pine trees decorated with red and white toys on either side of the door, with a large Christmas wreath and garlands of poinsettias above the window, the floor is covered with artificial snow, soft studio lighting with a warm glow coming from imitation window lights, bright and evenly diffused frontal lighting, soft shadows, a festive and cozy atmosphere, shot with a 50mm portrait lens, shallow depth of field, creamy bokeh in the background, highly detailed, photorealistic.
