Math Teacher Grading Papers in Classroom

A realistic classroom photo of a middle-aged male math teacher seated at a wooden desk, grading student papers with his right hand while leaning slightly forward. He has wavy dark brown hair, light skin, and wears a muted blue crew-neck sweater over a checked collared shirt. Show every face clearly with natural, detailed facial features. On the desk are 2 tall stacks of paper and folders, one on the left and one on the right, an open exam sheet in front of him, 3 loose pens in the foreground in blue, red, and transparent blue, 1 black zip pencil case at the front left, and 1 small black round cap or lid near the center-right of the desk. Behind him is a large dark green chalkboard filled with handwritten French mathematics notes and formulas in white chalk, including a function definition, a square root expression, a list of 5 numbered tasks, and limit notation. The room has soft natural indoor lighting, shallow depth of field, and a documentary-style academic atmosphere. Composition is landscape, medium shot, teacher centered, desk in the foreground, chalkboard spanning the entire background, highly realistic photography.
