**Stil und Format:** A realistic, high-resolution, modern photograph, professional hero section, wide landscape orientation, with a shallow depth of field (bokeh) to emphasize the foreground. **Szene und Akteure:** A first aid course in action. A friendly, middle-aged male instructor wearing a casual polo shirt demonstrates CPR (cardiopulmonary resuscitation) compressions on a realistic training mannequin (CPR dummy) on a mat on the floor. The instructor is focused on the technique, not looking at the camera. In the background, there are approximately 12 participants of mixed age and gender. They are dressed casually (not in business attire) and are sitting attentively on standard, simple seminar chairs (not office chairs), observing the demonstration. **Umgebung und Beleuchtung:** The setting is a clean, bright, and inviting training room (not sterile). It features warm, soft lighting, clear lines, and is well-maintained, suggesting a modern, professional, and trustworthy learning environment. The walls and flooring use neutral, calm colors. **Atmosphäre und Fokus:** The focus is on professionalism, safety, authenticity, and a positive, focused learning atmosphere. The image should look natural and unposed. **Zusätzliche Anweisungen:** No text, no logos, no branding. The color palette should be neutral, medical (e.g., subtle blues/greens), and trustworthy.
