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 in BOTH versions of the split-screen. The core identity must remain perfectly recognizable in both the glamorous Instagram version and the authentic reality version.

TRANSFORMATION DESCRIPTION: Create a split-screen composition showing two versions of the same person from the same photo shoot angle. The LEFT side is "INSTAGRAM" - a highly polished, influencer-style portrait with perfect makeup, smooth skin, flattering golden-hour lighting, and a trendy aesthetic. The RIGHT side is "REALITY" - showing the same person in the same pose but with natural lighting, visible skin texture, no makeup or minimal makeup, casual background, and authentic imperfections. Both sides must show the same person with identical facial features but dramatically different presentation styles.

STYLE AND AESTHETIC PARAMETERS:
- Split-screen format with a clean vertical divider line
- Instagram side: Professional influencer aesthetic, soft golden hour lighting, perfect makeup, subtle skin smoothing, trendy color grading (warm tones, slightly desaturated), polished and aspirational look
- Reality side: Natural window lighting or overhead room light, visible pores and skin texture, no makeup or minimal natural makeup, messy hair, casual background (bedroom, bathroom mirror, or living space), authentic and relatable look
- Both sides should be photorealistic with matching camera angles and facial expressions
- The contrast between sides should be striking but both should look like professional-quality photos
- Background on Instagram side: blurred cafe, golden hour window, or aesthetic studio backdrop
- Background on Reality side: cluttered desk, unmade bed, bathroom counter, or casual home environment

TECHNICAL QUALITY PARAMETERS:
- High resolution, 4K, detailed
- Sharp focus on face in both sections
- Professional quality split-screen composition
- Aspect ratio: 16:9 (landscape) or 1:1 (square) - ideal for social media
- Clean, even split down the middle
- Both images should have equal visual weight and quality
- Natural skin texture preserved on reality side while Instagram side shows perfected skin

NEGATIVE PROMPT GUIDANCE: Avoid: distorted features, unrealistic proportions, blurry face, loss of likeness, mismatched facial features between sides, asymmetrical composition, poor lighting quality, overexposed highlights, unnatural skin smoothing that looks like a filter, unrealistic beauty standards, mismatched skin tones between versions, poorly blended split-screen line

ADDITIONAL TIPS:
- For best results, use a photo where you're facing the camera directly
- You can specify preferred background settings in {additional_context}
- Mention specific makeup styles or fashion choices for the Instagram side
- Specify if you want the reality side to show morning-after, no-filter, or casual everyday look
