Set Planning — How Images Relate Within a Set

When to load: Phase 2 Shoot Plan, every time you decide what images make up a set and how they sequence.

Job: the business + design logic for arranging a multi-image set — pacing, variety, platform container, narrative arc. Domain knowledge about which images go in a set, in what order, why. The single-image and set-level quality requirements that each image must satisfy live in image-quality.md.

The set walks between two failure modes — drift (no harmony) and monotony (no variety). Pacing, variety axes, container layout and narrative arc are the four ways a director plans against monotony. (The harmony side is locked via image-quality.md — Aesthetic Baseline + cross-image QA.)

1. Pacing — the set as story

A real listing shoots like a film: scenes have a sequence, intensity rises and falls. 9 hero shots = exhausting; 9 detail shots = boring. Use pacing patterns.

The classic 4-beat structure

Beat	Job	Visual character
1. STATEMENT (the catch)	Stop the scroll, establish mood	Wide, bold, hero — the cover image
2. CONTEXT (the projection)	Help the buyer imagine using the product	Lifestyle, model + product, scene-rich
3. DETAIL (the proof)	Validate workmanship, material, build	Tight, calm, focused, no clutter
4. CONFIDENCE (the close)	Size, scale, variant, fit — answer the last objection	Functional, clean, informational

A 9-image set might rhythm as: 1=Statement, 2-4=Context (different beats), 5-7=Detail (different features), 8=Size, 9=Variant.

Pacing patterns by category (high-level)

Category	Suggested beat	Why
Apparel	Statement → Context (3 model angles) → Detail (fabric/work) → Flat-lay → Size chart	Visual decide first, validate fit second
3C	Statement (dark dramatic hero) → Context (in use) → Detail (ports/material) → Spec graphic → Box contents	Spec confidence + use scenarios
Beauty	Statement (packshot) → Texture / swatch → Shade range → Ingredient mood → Use scenario	Color/texture decide; ingredients re-validate
Furniture	Statement (room scene) → Multi-angle → Detail (joinery / hardware) → Size with human ref → Styling combinations	Scale + craftsmanship + fit-with-existing-decor
Food	Statement (final dish) → Ingredient close-up → Process / preparation → Packaging → Serving suggestion	Desire → trust → action

→ Per-category specific 组图分布表 (image roles + framing + lighting + selling point): categories/{NN-name}.md. The category files are the operational defaults; this section is the underlying pacing theory.

Anti-pattern: the flat set

A set with no pacing reads as 9 catalog shots — every image at the same distance, same energy, same tone. Symptoms:

Every image is a centered product on a similar background
No image is wider or tighter than the others by more than ~10%
Energy stays static (everything calm-still or everything busy-action)
No "rest" moments between busy ones

Fix: explicitly assign each image a beat in Phase 2 (# | Beat | Distance | Subject | Energy).

2. Variety axes — how not to make N identical images

Pick 3–4 axes and traverse each across the set.

Axis	Range	Use
Distance	wide → medium → close → macro	Most powerful axis. Mix of all four = visual rhythm
Subject	product-only / model+product / scene+product / detail-only	Variety in what's IN the frame
Energy	still elegant / mid-action / dynamic motion	Variety in what's HAPPENING. Implemented per-image via C13 pose-scene coherence
Tone within palette	dominant note / secondary note / accent-heavy / muted rest	Variety in the WEIGHT of the palette across the set
Density	calm / moderate / busy	Variety in INFORMATION DENSITY

The thumbnail test

Shrink every image of the set to thumbnail size, lay them in a row. Squint. If the row reads as N distinct silhouettes (different distances, different shapes, different brightness patterns), variety is working. If the row reads as N versions of the same blob, variety failed — even if each image individually is fine.

Axis Collision Check — mandatory before Phase 3 dispatch

After writing the Shoot Plan table in Phase 2, run this check before proceeding:

Fill in the variety axes for every image in the Shoot Plan table using this format: Sub-set · Distance · Subject (pick one value per axis from the ranges above).
Within each sub-set, scan for any two images whose Sub-set · Distance · Subject combination is identical. If found, that is a collision — adjust one of them (change Distance, change Subject, or move it to a different sub-set) before proceeding.
Across the full set, verify the Distance axis traverses at least 3 distinct levels (e.g. macro / close / medium / wide). A set that never reaches macro or wide has failed pacing.

Example collision (BAD): Image 1 = dark-studio · Distance=close · Subject=product-only; Image 4 = dark-studio · Distance=close · Subject=product-only → identical sub-set + Distance + Subject → must resolve by changing Image 4's sub-set (e.g. light-surface) or Distance (e.g. overhead 90°).

Example resolved (GOOD): Image 1 = dark-studio · Distance=close · Subject=product-only; Image 4 = light-surface · Distance=close · Subject=product-only → different sub-set → no collision.

Do not dispatch any generation until the Axis Collision Check passes.

3. Container layouts — where the set will be seen

The set's design must serve the platform container, not just stand alone.

Amazon — 7-image carousel (linear scroll)

Image 1 (main hero): MUST work as a tiny thumbnail in search results — silhouette + brand recognition in 0.5 seconds
Images 2-7: scrolling carousel, ~3 seconds each
Pacing recommendation: hero / lifestyle / lifestyle / detail / detail / size / variant
Each image must work alone (the buyer might leave after image 3); the SET must build trust progressively

Tmall PDP — main carousel + scrolling detail page

Top: 5-9 image carousel for the visual story
Below: long-scroll detail page where additional images intersperse with copy
Carousel needs cohesion (shared aesthetic baseline); detail-page images can be more functional / informational
Pacing: carousel is 90% aesthetic + 10% functional; detail page is 30% aesthetic + 70% functional

XHS / Pinterest / Instagram — 9-grid (visual harmony at thumbnail level)

Buyers see all 9 thumbnails at once before any single image
The grid as a WHOLE must have visual harmony — palette continuity, light universe consistency
If one thumbnail is dramatically different in palette / lighting / mood, the grid feels "off" before any single image is examined
Pacing: design the grid as a 9-cell composition — alternating distances, alternating subject types, with 1-2 visual "anchors" (high-density images) and 5-6 "rest" (lower-density images) for breathing room
Diagonal eye path: top-left → top-right → bottom-right → bottom-left

TikTok Shop / vertical scroll

Each image is a moment in a vertical scroll; the buyer can flick away in 1 second
Each image must be self-contained
Aspect: vertical 9:16 or 4:5 (not 1:1)
Energy bias: higher than other platforms — TikTok rewards motion / dynamism

Etsy / Shopee / DTC site

Often 5-6 images, gallery layout
Pacing: hero / lifestyle / detail / scale / variant / story-shot
Brand storytelling matters more; the set's aesthetic baseline IS the brand

→ Hard specs (aspect ratio / file size / banned elements) per platform: platform-specs.md.

4. Narrative arc — the set tells a story

DESIRE → TRUST → CONFIDENCE → CHOICE → CLOSURE
   ↓        ↓         ↓          ↓         ↓
 Hero    Lifestyle  Detail    Variants   Size /
 catch   project     proof    selection  scale
         self
         into it

Image type	Emotional job	Visual cue
Hero / packshot	Desire — "I want this"	Bold composition, strong palette, premium light
Lifestyle	Projection — "I see myself with this"	Aspirational scene, model in user's role, warm mood
Detail / macro	Trust — "this is well-made"	Sharp focus, revealing light, material truth
Spec / infographic	Confidence — "this fits my needs"	Clean callouts, honest specs, no exaggeration
Size / scale	Confidence — "it'll fit me / my space"	Real reference object, no perspective trick
Variant / multi-color	Choice — "I have options"	Side-by-side, identical lighting, easy comparison
Closure shot	Sealing — "yes, I'm buying"	Often the hero re-presented, brand-perfect

Don't skip emotional beats. A set with 7 hero shots + 0 detail shots feels untrustworthy. A set with 7 detail shots + 0 hero shots feels like a manual, not a listing.
