Act as a director of photography and AI image generation expert. Write a detailed prompt, in English, to generate a photorealistic portrait of subject using tools like Midjourney, DALL-E or similar. Include, described and comma-separated: 1) Subject and expression. 2) Framing and pose (e.g., close-up, half body). 3) Lighting (e.g., soft natural light, golden hour). 4) Lens and camera (e.g., 85mm, f/1.8). 5) Environment and background. 6) Overall style and mood. Consider the final goal where the image will be used, e.g., professional profile photo. Generate 3 prompt variations with different styles and add suggested negative parameters to avoid distortions. Present each prompt in a separate block, ready to copy.
