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 them into an aquariumist character. Maintain all facial proportions, birthmarks, distinctive features, and natural expressions without any alteration to the person's core identity.

TRANSFORMATION DESCRIPTION: Transform the person into a professional aquariumist or fish keeper. Dress them in appropriate aquarium work attire such as a dark blue or khaki work apron, casual button-down shirt, or polo shirt with rolled sleeves. Add subtle water splashes on the clothing and skin. Include realistic aquarium environment elements around them - glass tank reflections, aquatic plants, fish silhouettes visible in water reflections, and soft blue-green lighting from aquarium tanks. The person should appear as if standing near a large aquarium display, with water reflections cast across their face and clothing. Their expression should be focused, knowledgeable, and passionate about aquatics - perhaps holding a fish net, water test kit, or fish food container. Add subtle moisture droplets on skin and clothing for authenticity.

- Photorealistic portrait photography style with cinematic quality
- Natural mixed lighting: soft blue-green aquarium lighting combined with warm ambient studio light
- Cool color palette with aquamarine, teal, and deep ocean blues complemented by warm skin tones
- Professional depth of field with slight background blur (bokeh) on aquarium elements
- Water reflections and caustic light patterns subtly visible on face and clothing
- High detail on fabric textures (apron, shirt) and water droplets

- Moisture and condensation effects on tank glass and surfaces

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus maintained on face with natural skin texture preservation
- Professional quality, studio-grade portrait photography

NEGATIVE PROMPT GUIDANCE: Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, unnatural clothing attachment, exaggerated water effects, cartoonish style, deformed hands, extra fingers, plastic skin texture, oversaturated colors, poor lighting balance, unnatural water droplet placement, identity alteration
