Portrait Smartphone en Contre-Plongée sur Canapé

A realistic vertical smartphone social-media portrait of a young adult woman sitting on a gray fabric sofa against a warm white indoor wall with a small white square light switch visible on the left. She is wearing a [deep navy sleeveless high-neck ribbed knit dress]. The dress is fitted yet casual, featuring distinct vertical ribbing texture, natural stretch across the torso, and subtle folds at the waist and hem. She wears simple gold hoop earrings and has [long side-parted cool-brown wavy hair] draped softly over one shoulder with realistic flyaway strands. She leans slightly back into the sofa, head tilted gently upward while gazing directly downward toward the camera with a calm, cool, unsmiling expression. Composition & Camera: Shot from a low, knee-level perspective pointing upward in a 9:16 aspect ratio. One knee and thigh are close to the lens in the lower foreground creating strong perspective depth, placing her face in the upper half with open wall space above. Casual, imperfect framing typical of a smartphone camera. Lighting & Color: Soft diffused indoor window light entering from the front-left, casting creamy highlights and gentle beige-gray shadows across fair skin with neutral pink undertones. Lightly matte, smooth skin texture with natural variation. Style & Details: Natural mobile photography aesthetic, subtle beauty retouching, slight lens sharpness, tactile knit and fabric textures, and no harsh flash.
