IDENTITY PRESERVATION INSTRUCTION:
Using the uploaded photo as reference, preserve the person's exact facial features, face shape, eye color, skin tone, and unique characteristics while transforming the scene and attire. The facial identity must remain 100% recognizable.

TRANSFORMATION DESCRIPTION:
Transform the person into a professional oceanologist or marine biologist on an expedition. The subject should be wearing appropriate field gear including a waterproof windbreaker or jacket (in navy blue, white, or bright safety orange), a functional life vest or buoyancy aid over the jacket, and a professional communication headset or radio. The setting is the deck of a research vessel or a coastal observation station with the ocean visible in the background. The person should look focused and engaged with their scientific work, perhaps holding a tablet, a sample jar, or adjusting equipment. The environment should feel authentic to a maritime research setting.

STYLE AND AESTHETIC PARAMETERS:
- Art Style: Photorealistic, cinematic, and documentary-style photography. High-end portrait quality.
- Lighting: Natural, slightly overcast daylight typical of maritime environments. Soft diffused light on the face to maintain visibility of features, with dramatic backlighting from the ocean or sky to create depth.
- Color Palette: Cool tones dominated by ocean blues, teals, and slate grays, contrasted with the warm technical tones of the gear (orange safety accents or crisp whites). The mood is professional, adventurous, and crisp.
- Background Treatment: The background should feature a realistic ocean environment-either open sea with waves, a misty coastline, or the deck of a research ship. It should be slightly blurred (bokeh effect) to keep focus on the subject, but detailed enough to establish the setting.

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed, ultra-sharp.
- Sharp focus on face and eyes; maintain natural skin texture and pores.
- Professional quality, 8k, masterpiece, trending on ArtStation.
- Aspect Ratio: 3:4 (vertical portrait orientation) suitable for profile pictures.

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic clothing proportions, blurry face, loss of likeness, cartoonish elements, low resolution, grainy texture, unnatural skin smoothing, deformed hands, extra limbs, mutated gear, watermark, text, signature.

FINAL INSTRUCTIONS:
Ensure the transformation looks natural and believable. The gear must integrate seamlessly with the person's body and the original photo's lighting conditions. The ocean background should enhance the atmosphere without overpowering the subject's face.
