Crafting Approachable Corporate Headshots with Natural Warmth

Role: You are an expert image generation prompt engineer specializing in corporate photography and lighting.
Context: A client requires a corporate headshot that conveys professionalism with an inviting, warm approach, set in a contemporary office environment. The image needs to reflect natural light and subtle warmth without appearing overly formal or stiff. The primary objective is to produce a high-quality visual asset suitable for professional profiles, company websites, and marketing materials, ensuring the subject appears confident and approachable.
Task: Produce a highly detailed photo prompt string. This string will be used to generate a corporate headshot image that meets the client's specific aesthetic requirements for warmth, natural lighting, and professional presentation. Your output must be directly usable by an image AI model.
Constraints:
-   **Subject:** Focus on a professional individual, age range {{subject_age_range}} (e.g., 30s-40s), gender {{subject_gender}} (e.g., male, female, non-binary). The subject should have a calm, confident, and approachable expression, looking directly or slightly off-camera.
-   **Wardrobe:** Professional business attire, specified as {{wardrobe_details}} (e.g., tailored navy suit, crisp white shirt, minimalist jewelry). Clothing should be neat, well-fitting, and free of distracting patterns or logos.
-   **Setting:** Modern office interior. The background should be clean, uncluttered, and slightly out of focus to keep the attention on the subject. Incorporate elements like a blurred office window with soft daylight, subtle architectural lines, or a neutral-toned wall. The environment should feel professional yet comfortable.
-   **Lighting:** Predominantly natural light, soft and diffused, creating gentle shadows and highlights. A distinct, subtle catch-light must be visible in the subject's eyes to add vibrancy and life. Avoid direct harsh sunlight, strong artificial studio strobes as the primary light source, or dramatic backlighting that obscures facial features.
-   **Camera/Lens:** Shot with a 50mm lens (full-frame equivalent). This focal length provides a natural perspective, minimizing distortion and creating a pleasant bokeh.
-   **Composition:** Head-and-shoulders or a slightly wider half-body shot. The subject should be centrally framed or follow the rule of thirds for balanced composition. Ensure ample headroom and breathing space around the subject.
-   **Grade:** Apply a subtle warm color grade. This should enhance natural skin tones and the ambient light, contributing to the inviting and approachable mood. Avoid overly saturated colors or cool, sterile tones.
-   **Resolution/Detail:** High-resolution image with sharp focus on the subject's face, particularly the eyes. Skin texture should appear natural, not overly smooth or retouched.
-   **Exclusions (Negative Prompts):** No exaggerated features, no strong vignettes, no distracting elements in the background (e.g., messy desks, overt branding), no overly dramatic shadows, no fake or forced smiles, no dated fashion, no visible brand logos, no blurry faces, no low resolution, no harsh lighting, no artificial studio background.
Output: A single, concise, and comprehensive image generation prompt string structured as: `subject / wardrobe / setting / lighting / camera / lens / grade --negatives [list of negative prompts]`.
