Confident White Teacher in a Modern Classroom

Photorealistic image of a confident White male teacher in a bright classroom. He stands at the front, wearing a crisp light-blue blazer over a white shirt with sleeves casually rolled, no tie, gesturing with one hand as he speaks. Warm daylight streams through large windows, illuminating the room. Behind him is a chalkboard with diagrams and a projector; desks and students are visible in the foreground. The scene is shot at eye level with a 50mm lens, shallow depth of field, high detail on skin, hair, and fabrics, natural skin tones, and subtle cinematic color grading.
