[Let's Try It] Reproducing Emotional Compositions with Prompts

Conclusions

• Lighting and time-of-day specifications contribute significantly to atmosphere. Keywords like golden hour, moody corridor lighting, and rainy atmosphere affected color temperature and light direction in 3/3 images.
• Classroom × golden hour (A) stably generated warm diagonal light streaming through windows. Paired with a desk-and-chair classroom background, the after-school mood was achieved in 3/3.
• Library reaching-for-shelf composition (B) was reproduced stably in 3/3. The reaching-for-shelf pose in a bookshelf aisle has high reproducibility.
• Rooftop low angle + wind (C) consistently generated dramatic compositions. An upward-looking composition with a cloudy sky background and wind-blown hair were reflected in 3/3.
• Rainy school gate + umbrella (D) — ground reflections were effective. The combination of wet ground reflections and rainy atmosphere stably generated the feel of rain.
• Corridor turn + film grain (E) had stable moody tones. A depth-filled corridor with film grain texture was confirmed in 3/3.
• Emotional compositions work not just for uniform × school scenes, but also casual wear × non-school settings (cafe, riverside, rainy shopping street). neon reflections on wet pavement in particular is a strong atmospheric expression.
• Cafe window × golden hour (F) stably showed warm light streaming through glass. A more mature atmosphere different from the uniform scenes was achieved.
• Riverside × dusk (G) — the combination of wind and sunset was effective. A bridge and orange sky appeared in the background with hair blowing in the wind.
• Rainy shopping street × neon reflections (H) — wet pavement neon reflections were reproduced. Combined with an umbrella, an urban emotional composition was established.

What You’ll Learn

• The combined effect of “location × pose × lighting” in school and casual scenes
• Stability of each composition (variation across 3 seeds)
• Effectiveness of lighting and effect specifications for creating atmosphere
• Atmospheric differences between uniform × school and casual × non-school settings

Experiment Design

Subject common to conditions A–E: 1girl, 32yo japanese actress, school uniform Conditions F–H use casual wear variations (individual clothing specified per condition)

Control: Indoor × Standing

seed 42	seed 123	seed 789

Observations: All 3 images show a standard composition of a uniformed subject standing indoors. seed 42 stands in front of a classroom blackboard in vest + blouse + checkered pleated skirt. seed 123 stands in front of bookshelves. seed 789 is against a wall background. Lighting is uniform indoor light with no special atmosphere. The pose is close to fully upright with minimal movement.

Condition A: After-School Classroom × Golden Hour

seed 42	seed 123	seed 789

Observations: A classroom background was reproduced in 3/3, with warm evening light from windows streaming in. The contrast with the control is clear — golden hour light colors the entire space. seed 42 shows the subject by the window with the contrast between outside greenery and warm light visible. seed 123 is in a sailor uniform with hands on a classroom desk. seed 789 is also in a classroom with diagonal sunset light. The “leaning against desk” specification was reflected as a desk-leaning pose in 2/3 images.

Condition B: Library × Reaching for Shelf + Side Lighting

seed 42	seed 123	seed 789

Observations: A library with bookshelves was reproduced in 3/3, with the reaching-for-shelf pose stably reflected. seed 42 shows a natural depiction of the subject reaching sideways to a shelf. seed 123 is in a blazer uniform reaching up to a higher shelf. seed 789 is similarly reaching in a bookshelf aisle. The warm library side lighting produced calm warm-toned lighting in 3/3. The reaching-for-high-shelf pose specification was stable, with arm-raised actions in 3/3.

Condition C: Rooftop × Wind + Low Angle

seed 42	seed 123	seed 789

Observations: Rooftop background was reproduced in 3/3, with upward-looking low-angle compositions achieved. Wind blowing hair and skirt was reflected in 3/3. seed 42 shows a sailor uniform with a dramatic cloudy sky in the background — a powerful composition. seed 123 also has a dramatic cloudy sky and impressive wind-blown hair. seed 789 shows an upward-looking pose with sailor uniform skirt blowing in the wind. The dramatic sky specification produced a heavily clouded dramatic sky in 2/3 images.

Condition D: Rainy School Gate × Umbrella + Ground Reflections

seed 42	seed 123	seed 789

Observations: A rainy atmosphere was reproduced in 3/3. The school gate appeared as gate fencing or gate doors in 3/3. The clear umbrella was reflected as a transparent umbrella in 3/3. The wet ground reflections specification produced wet reflective ground in 3/3, contributing significantly to the rainy feel. seed 42 shows a sailor uniform holding an umbrella in front of a fence. seed 123 is in a blazer uniform in front of the gate with puddle reflections visible. seed 789 is also in a sailor uniform with an umbrella, standing between open gate doors. The rainy atmosphere was reflected as a hazy, misty air quality.

Condition E: Corridor × Turning + Moody + Film Grain

seed 42	seed 123	seed 789

Observations: A depth-filled hallway was reproduced in 3/3, with the turning back pose stably reflected. The moody dim lighting specification produced darker tones in 3/3, with partial fluorescent lighting creating an impressive hallway composition. Film grain was confirmed as granular texture in 3/3, creating a film-photo-like quality. The muted tones specification reduced saturation for a muted overall color palette. seed 42 is in a sailor uniform turning in the center of a long hallway. seed 123 is a blazer variation in a depth-filled hallway. seed 789 is in a sailor uniform turning in a dim hallway.

Condition F: Cafe Window × Golden Hour (Casual Wear Variation)

Switching from uniform to casual wear to test emotional compositions in non-school settings.

seed 42	seed 123	seed 789

Observations: seed 42 shows the subject sitting at a cafe window seat with warm golden hour light streaming through the glass. A striped casual dress is worn, and a latte sits on the table. A more mature atmosphere compared to the uniform scenes was achieved. The golden hour light through glass specification softly illuminated the entire space with warm window light. A wooden cafe table and chairs appear in the background, resulting in an everyday yet warm composition.

Condition G: Riverside × Dusk (Casual Wear Variation)

seed 42	seed 123	seed 789

Observations: seed 42 shows the subject walking along a riverside at dusk. A light cardigan is worn with hair blowing in the wind. An orange sunset sky and bridge are visible in the background. The silhouette specification is working — the subject is somewhat backlit in a near-silhouette expression. The orange sky specification colored the sky orange with the water surface also reflecting the color. The combination of the open riverside space and dusk atmosphere generates a stable emotional composition.

Condition H: Rainy Shopping Street × Neon Reflections (Casual Wear Variation)

seed 42	seed 123	seed 789

Observations: seed 42 shows the subject in a gray hoodie holding an umbrella on a rain-soaked shopping street. The wet pavement reflects neon colors (pink, blue, yellow) — the neon reflections on wet pavement specification is working effectively. Shopping street signs and storefronts line the background with passersby visible, creating an urban atmosphere. Compared to condition D’s rainy school gate, this non-school urban scene has a more information-dense frame composition.

Summary Comparison

Composition Stability

Keywords That Were Effective for Atmosphere

Note: The main takeaway from this test is that lighting specifications are highly stable. The combination of location, lighting, and clothing can expand the variation space considerably. neon reflections on wet pavement had especially strong atmospheric effect and is worth keeping in mind.
