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 appearance into a professional engineer. The original identity must remain completely recognizable with no distortion to facial structure or key identifying marks.

TRANSFORMATION DESCRIPTION:
Transform the person into a professional engineer wearing authentic work attire. Add a high-visibility safety vest (yellow/orange) over their current clothing, a hard hat or construction helmet on their head, and optional safety glasses. Place them in an industrial or technical environment such as a construction site, engineering workshop, or technical office. Include relevant engineering tools like blueprints, a tablet with schematics, or technical equipment in their hands or nearby. The transformation should look natural and authentic to their body type and style.

STYLE AND AESTHETIC PARAMETERS:
- Photorealistic portrait style with professional photography quality
- Natural studio lighting or soft industrial lighting that flatters the face
- Professional color grading with warm skin tones and realistic work uniform colors
- Background: blurred industrial setting, construction site, or clean technical workshop
- High-visibility vest should have realistic fabric texture and reflective details
- Hard hat should look authentic with proper shading and material texture
- Safety glasses should be clean and properly fitted to face shape
- Overall mood: professional, competent, and authentic

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face and facial features
- Professional quality portrait photography
- Aspect ratio: 1:1 or 4:3 (recommended for portraits)
- Natural skin texture preserved
- Professional depth of field with slight background blur
- Crisp details on clothing and equipment

NEGATIVE PROMPT GUIDANCE:
Avoid: distorted facial features, unrealistic proportions, blurry face, loss of likeness, poorly integrated clothing, unnatural lighting on face, mismatched skin tones, cartoonish appearance, low quality, pixelation, deformed hands, extra fingers, fused equipment, floating objects, unnatural hard hat placement, safety glasses cutting into face

Additional Tips:
- For more casual engineering look, request "casual engineer" or "field engineer"
- For high-tech engineering, specify "software engineer" or "lab coat"
- For construction focus, specify "construction site background" or "heavy machinery"
- Adjust safety vest color by specifying "orange vest" or "yellow vest"
