A ten-year-old girl stands on a low stool playing a full-size double bass with a bow in a sunlit wooden music room, concentrating, sheet music stand beside her. Authentic documentary photograph, natural colour, believable skin texture and proportions, correct hands with five fingers, physically accurate objects, shallow but natural depth of field. The double bass is taller than the child, four strings, correct bow hold, f-holes and scroll accurate, the sheet music is blank or blurred. No text, no letters, no numbers, no logos, no signage, no watermark, no borders.
