# Photo Composition Critic

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

## DECISION POINTS

### Primary Analysis Path Selection

```
If PORTRAIT/PERSON as main subject:
  ├── First check: Eye sharpness and face visual weight
  ├── Assess: Pose dynamics and gesture flow
  └── Apply: Figure-ground separation priority

If LANDSCAPE/ARCHITECTURE:
  ├── First check: Horizon placement and visual weight balance
  ├── Assess: Depth layering (foreground/mid/background)
  └── Apply: Dynamic symmetry for structure analysis

If DOCUMENTARY/STREET:
  ├── First check: Decisive moment capture quality
  ├── Assess: Visual narrative clarity
  └── Apply: Gestalt principles for scene reading

If MACRO/DETAIL:
  ├── First check: Subject isolation and background management
  ├── Assess: Pattern and texture emphasis
  └── Apply: Color contrast analysis priority
```

### Framework Application Order

```
If high visual complexity (>5 main elements):
  └── Start with Gestalt → Visual Weight → Color → Dynamic Symmetry

If simple composition (≤3 main elements):
  └── Start with Dynamic Symmetry → Visual Weight → Color → Gestalt

If monochromatic/B&W:
  └── Skip color analysis → Focus on Value contrast → Arabesque flow

If strong geometric elements:
  └── Prioritize Dynamic Symmetry → Check rule of thirds as fallback
```

### ML Score Interpretation Strategy

```
If NIMA score ≥6.5 AND manual analysis finds major flaws:
  └── Flag as "technically proficient but conceptually weak"

If NIMA score <5.0 BUT strong artistic intent evident:
  └── Flag as "polarizing work - assess against genre standards"

If LAION aesthetic >0.7 AND color harmony is complex:
  └── This is likely intentional artistic choice, not error
```

## FAILURE MODES

### **Rule of Thirds Dogma**
- **Symptom**: Automatically placing subjects on intersection points regardless of visual weight
- **Detection**: If recommending thirds placement without analyzing visual balance first
- **Fix**: Analyze visual weight center first, then consider dynamic symmetry before defaulting to thirds

### **NIMA Score Worship**
- **Symptom**: Using ML scores as primary or only quality metric
- **Detection**: If citing NIMA/LAION scores without theoretical framework analysis
- **Fix**: Use ML scores as confirmation data, not primary assessment. Always lead with compositional analysis

### **Color Harmony Oversimplification**
- **Symptom**: Recommending monochromatic palettes for all "harmony" issues
- **Detection**: If suggesting color matching without considering Itten's 7 contrasts
- **Fix**: Identify specific contrast type needed (hue, value, temperature, etc.) before recommending changes

### **Genre Confusion**
- **Symptom**: Applying portraiture standards to documentary work or vice versa
- **Detection**: If critique doesn't acknowledge genre-specific quality indicators
- **Fix**: Establish genre context first, then apply appropriate assessment framework

### **Technical Fixation**
- **Symptom**: Focusing only on exposure/sharpness while ignoring compositional strength
- **Detection**: If more than 50% of critique is technical issues without aesthetic analysis
- **Fix**: Balance technical and aesthetic assessment - great composition can overcome minor technical flaws

## WORKED EXAMPLES

### Example 1: Portrait Analysis

**Initial Image**: Corporate headshot with subject centered, plain background, harsh lighting

**Step-by-step analysis**:
1. **Genre identification**: Professional portrait → Priority on face clarity and professional impression
2. **Visual weight assessment**: Subject's dark suit against light background = good figure-ground separation, but centered placement creates static composition
3. **Gestalt analysis**: Strong closure (complete figure), good similarity in clothing tones, but lack of continuity for eye movement
4. **Dynamic symmetry check**: Subject placement at geometric center misses both thirds and phi ratios
5. **Color evaluation**: Monochromatic blue-grey palette = professional but lacks warmth

**Expert catches that novice misses**: The lighting creates unflattering shadows under eyes, but the composition's static nature is the bigger issue. Moving subject to left third and angling body would create more dynamic energy.

**Recommendations**: 
- Reposition to left third for asymmetrical balance
- Add subtle warm accent in background or clothing
- Adjust lighting to create gentle directional flow

### Example 2: Landscape Critique

**Initial Image**: Mountain sunset with horizon at center, oversaturated colors

**Decision path navigation**:
1. **Framework selection**: Landscape → Start with dynamic symmetry analysis
2. **Horizon placement**: Dead center violates both visual weight and dynamic symmetry principles
3. **Color harmony assessment**: Extreme saturation suggests complex harmony type, but likely post-processing artifact
4. **Visual weight check**: Sky dominates due to warm colors and saturation, but equal space allocation fights this
5. **NIMA prediction**: Likely scores high (6.0+) due to sunset appeal, but compositionally weak

**Trade-off discussion**: 
- **Option A**: Lower horizon (bottom third) to emphasize dramatic sky
- **Option B**: Raise horizon (top third) to feature foreground elements
- **Option C**: Crop to panoramic format to resolve vertical balance issue

**Alternative approaches**: 
- Desaturate colors for more natural harmony
- Use graduated filter effect to balance sky exposure
- Consider B&W conversion to emphasize form over color

## QUALITY GATES

- [ ] Genre context established and appropriate framework selected
- [ ] At least 3 compositional frameworks analyzed (Visual Weight, Gestalt, Dynamic Symmetry, or Arabesque)
- [ ] Color harmony type identified and assessed against genre appropriateness
- [ ] ML scores (if available) interpreted with theoretical context, not used as primary metric
- [ ] Technical issues balanced with aesthetic analysis (neither ignored nor overemphasized)
- [ ] Specific, actionable recommendations provided for improvement
- [ ] Alternative approaches or crop options suggested when applicable
- [ ] Anti-patterns explicitly avoided (no rule-of-thirds dogma, genre confusion, etc.)
- [ ] Visual weight center identified and balanced against formal composition rules
- [ ] Failure modes checked: not falling into NIMA worship, color oversimplification, or technical fixation

## NOT-FOR BOUNDARIES

**Do NOT use this skill for**:
- **Photo editing/retouching** → Use `native-app-designer` instead
- **Generating new images** → Use Stability AI directly
- **Basic object detection** → Use `clip-aware-embeddings` instead
- **Creating photo collages** → Use `collage-layout-expert` instead
- **Simple image similarity comparison** → Use `clip-aware-embeddings` instead
- **Commercial photography pricing** → Defer to photography business expert
- **Camera settings recommendations** → Defer to technical photography expert
- **Copyright/legal image analysis** → Defer to legal expert

**Delegate when**:
- User needs actual photo manipulation tools
- Request involves generating rather than analyzing images
- Focus is on metadata/EXIF rather than aesthetic quality
- Request requires specialized technical camera knowledge beyond composition
