Most Common Mistakes and Solutions

Mistake #1: Poor Source Image Quality

The Problem: Starting with low-quality, compressed, or poorly lit source images.

Common Symptoms:

  • Consistently blurry or pixelated results
  • Unnatural skin textures or facial details
  • Color distortion that persists across different edits
  • Difficulty maintaining character consistency

Root Causes:

  • Using heavily compressed social media images
  • Screenshots instead of original files
  • Images with poor lighting or focus
  • Too-small resolution for intended use

Solutions:

Immediate Fix:

"Enhance image quality and resolution while maintaining exact facial features and natural appearance, professional photography quality"

Best Practices:

  • Always use the highest resolution source available
  • Avoid images with Instagram/Snapchat filters
  • Ensure good lighting on the subject's face
  • Use PNG format when possible for source images
  • Take new photos if originals are inadequate

Prevention Strategy: Create a "source image quality checklist":

  • Resolution: 1024x1024px minimum
  • Format: Uncompressed (PNG preferred)
  • Lighting: Even, natural lighting
  • Focus: Sharp details, especially facial features
  • Compression: Minimal compression artifacts

Mistake #2: Overly Complex or Conflicting Prompts

The Problem: Trying to accomplish too many changes in a single prompt or providing contradictory instructions.

Common Symptoms:

  • Results that partially address your request
  • Unexpected elements or style mixing
  • Artificial or "over-processed" appearance
  • Inconsistent quality across different parts of the image

Problematic Examples: ❌ "Make this person look professional but also casual and artistic while changing the background to both indoor and outdoor settings with bright but moody lighting"

❌ "Transform into business attire and beach wear simultaneously"

❌ "Make it look natural but also very dramatic and stylized"

Solutions:

Immediate Approach - Simplification: Break complex requests into sequential steps:

Step 1: "Transform casual clothing to professional business attire while maintaining exact facial features and natural expression"

Step 2: "Place in modern office environment with appropriate professional lighting to match the business attire"

Step 3: "Enhance for executive-level professional photography quality"

Better Prompt Structure:

"[Single primary change] while maintaining [specific preservation requirements], ensuring [quality standards] and [style consistency]"

Prevention Strategy:

  • Focus on one major change per prompt
  • Use sequential processing for complex transformations
  • Avoid contradictory descriptors
  • Test simple versions before adding complexity

Mistake #3: Inadequate Character Preservation Instructions

The Problem: Not providing specific enough instructions for maintaining character identity during edits.

Common Symptoms:

  • Subtle but noticeable changes in facial features
  • Expression shifts from the original
  • Skin tone or eye color variations
  • Loss of distinctive characteristics

Weak Examples: ❌ "Keep the person the same" ❌ "Don't change their face" ❌ "Maintain their appearance"

Solutions:

Strong Preservation Language:

"Maintain exact facial bone structure, eye color, skin tone, expression, and all distinctive facial features while [specific change request]"

Feature-Specific Preservation:

"Preserve precise eye shape and color (specify: brown/blue/green), nose proportions, jawline definition, natural skin texture, and authentic expression while transforming [specific elements]"

Professional Template:

"Transform [specific element] while maintaining the person's identical facial geometry, natural expression including eye direction and micro-expressions, authentic skin characteristics, and exact bone structure proportions"

Best Practices:

  • Always specify what to preserve, not just what to change
  • Include specific details about distinctive features
  • Mention expression and emotional tone
  • Reference skin characteristics and eye color when critical

Mistake #4: Ignoring Lighting and Environmental Harmony

The Problem: Not considering how lighting should integrate when making environmental or clothing changes.

Common Symptoms:

  • Subject looks "cut and pasted" into new environment
  • Unnatural shadows or lack of shadows
  • Lighting direction inconsistencies
  • Color temperature mismatches

Poor Integration Examples:

  • Indoor lighting on subject in outdoor environment
  • No shadows when shadows should exist
  • Different light sources creating conflicting highlights

Solutions:

Lighting Integration Prompts:

"Adjust subject lighting to match environmental lighting direction and intensity, ensuring natural shadows and highlights consistent with [lighting source]"

Environment-Specific Lighting:

"Professional office environment: Soft natural window lighting from camera left, creating gentle shadows appropriate for indoor corporate setting"

"Outdoor natural setting: Golden hour lighting with warm directional sunlight, natural outdoor shadows and environmental reflections"

Advanced Integration:

"Transform background to [new environment] while adjusting all lighting on the subject to match the new environment's natural light source, including appropriate shadows, reflections, and color temperature"

Prevention Checklist:

  • Identify light source direction in target environment
  • Specify shadow requirements
  • Consider color temperature (warm/cool)
  • Account for environmental reflections

Mistake #5: Unrealistic Expectations or Physics

The Problem: Requesting transformations that violate natural physics or realistic proportions.

Common Symptoms:

  • Proportions that look "off" or unnatural
  • Clothing that doesn't fit properly
  • Impossible physical configurations
  • Scale inconsistencies

Unrealistic Examples: ❌ "Make the person 7 feet tall in a normal-sized room" ❌ "Add clothing that's clearly the wrong size" ❌ "Place large objects in spaces too small to contain them"

Solutions:

Reality-Based Prompting:

"Ensure realistic proportions appropriate for human anatomy and environmental scale, maintaining believable physics and natural appearance"

Size and Scale Guidance:

"Integrate elements at realistic scale appropriate for the environment, ensuring proper proportions and believable spatial relationships"

Physics Considerations:

"Apply realistic fabric draping, weight distribution, and natural positioning that follows physical laws and human anatomy"

Best Practices:

  • Research realistic examples of what you're requesting
  • Consider environmental scale and proportions
  • Include physics-based language in prompts
  • Test with simpler versions first
