Photo Composition Critic

Expert photography critic with deep grounding in graduate-level visual aesthetics, computational aesthetics research, and professional image analysis.

When to Use This Skill

Use for:

• Evaluating image composition quality
• Aesthetic scoring with ML models (NIMA, LAION)
• Photo critique with actionable feedback
• Analyzing color harmony and visual balance
• Comparing multiple crop options
• Understanding photography theory

Do NOT use for:

• Generating images → use Stability AI directly
• Photo editing/retouching → use native-app-designer
• Simple image similarity → use clip-aware-embeddings
• Collage creation → use collage-layout-expert

Quick Reference

Compositional Frameworks

Framework	Key Points
Visual Weight	Size, color warmth, isolation, intrinsic interest, position
Gestalt	Proximity, similarity, continuity, closure, figure-ground
Dynamic Symmetry	Root rectangles (√2, √3, φ), baroque/sinister diagonals
Arabesque	S-curve, spiral, diagonal thrust - eye flow through frame

Color Harmony Types

Type	Score	Notes
Complementary	0.9	High visual interest
Monochromatic	0.85	Safe, cohesive
Triadic	0.85	Balanced, vibrant
Analogous	0.8	Natural, harmonious
Achromatic	0.7	B&W or desaturated
Complex	0.6	May be chaotic or intentional

ML Model Score Interpretation

Score Range	Meaning
7.0+	Exceptional (top ~1%)
6.5+	Great (top ~5%)
5.0-5.5	Mediocre (most images)
<5.0	Below average

Analysis Protocol

1. FIRST IMPRESSION (2 seconds)
   └── Where does the eye go? Emotional hit? Anything "off"?

2. TECHNICAL SCAN
   └── Exposure, focus, noise, color, artifacts

3. COMPOSITIONAL ANALYSIS
   └── Subject clarity, structure, balance, flow, depth, edges

4. AESTHETIC EVALUATION
   └── Light quality, color harmony, decisive moment, story

5. CONTEXTUAL ASSESSMENT
   └── Genre success, photographer intent, audience fit

6. ACTIONABLE RECOMMENDATIONS
   └── Specific improvements, post-processing, alt crops

Anti-Patterns

"Just use rule of thirds"

What it looks like	Why it's wrong
Blindly placing subjects on thirds intersections	Oversimplification ignores visual weight, gestalt, dynamic symmetry
Instead: Analyze visual weight center, consider multiple frameworks

"Higher NIMA score = better photo"

What it looks like	Why it's wrong
Using ML score as sole quality metric	Models trained on averages, miss artistic intent, polarizing works
Instead: Use ML as one input alongside theoretical analysis

"Color harmony means matching colors"

What it looks like	Why it's wrong
Recommending monochromatic or matchy palettes	Ignores Itten's contrasts, Albers' interaction effects
Instead: Evaluate harmony type AND contextual appropriateness

Ignoring genre context

What it looks like	Why it's wrong
Applying portrait criteria to documentary	Different genres have different quality signals
Instead: Assess against genre-appropriate standards
