Base Prompt
Cherry blossom spatial spread observed in full body shots.
A00: control
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: Full body shot standing under cherry trees in a park. Wearing white blouse and beige long skirt. 1 to 3 cherry trees visible in background, flowers spread in the upper frame. Petals scattered on the ground. Subject standing in the center of the frame with full body visible.
A01: under tree
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: Compared to control, cherry tree trunks are positioned closer to the subject. Cherry branches cover the upper frame with a flower canopy spread. s1 shows a composition standing under a cherry avenue with multiple trees receding in depth. s2 shows multiple tree trunks on the left and right with cherry flowers covering overhead. The distance to cherry trees is shorter than in control.
A02: sakura tunnel
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: The sakura tunnel specification produces an avenue composition with cherry trees on both sides in all 3 images. Branches cross in an arch overhead, creating the tunnel effect. s1 is walking on a paved path with strong perspective. s2 is standing in the center of the road with tree trunks on both sides of the frame. Flowers cover overhead with petals scattered on the ground. Composition is significantly different from control.
A03: wide hanami
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: Cherry blossom tunnel-like composition appeared, similar result to sakura tunnel. s1 is standing in the center of an avenue with figures visible in the distance. s2 is a full body shot standing under a cherry arch. More cherry trees than control, with larger flower area in frame. However, no clear difference from sakura tunnel was confirmed.
A04: petal shower
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: The petal shower specification produces petals scattering in the air in all 3 images. Large quantities of petals also accumulate on the ground, clearly more pink to white ground area than control. Multiple cherry trees in the background with high flower density. The scattering petals are an element not in control, with clear effect.
A05: river sakura
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: The river specification produces a river on the right side of the frame in 2 images (s1, s2). The composition shows standing on a riverside promenade with cherry branches overhanging the river. The opposite bank may also show cherry blossoms. The water surface element not in control is added, with clear compositional change. Cherry blossom density is equal to or slightly higher than control.
A06: long shot
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: Subject size is slightly smaller than control, with surrounding cherry trees visible in a wider area. s1 shows multiple large cherry trees lined up in the background with flowers covering a wide upper area. However, full body still in frame same as control, and angle difference is modest. Cherry blossom area ratio is larger than control.
A07: picnic
| seed 1 | seed 2 | seed 3 |
|---|---|---|
 |  |  |
Observations: s1 is sitting on the ground with a plaid picnic sheet, basket, camera, straw hat, and bag. Clothing changed to cardigan + denim pants, with “white blouse, long skirt” ignored. s2 similarly shows picnic sheet props. One large cherry tree in the background. Props are added, but clothing specification conflict occurred.
Summary
| Condition | Blossom density | Composition change | Petal scatter | Side effects |
|---|---|---|---|---|
| control | Medium | Baseline | None | None |
| under tree | High | Small (closer to trees) | None | None |
| sakura tunnel | High | Large (avenue tunnel) | Yes (ground) | None |
| wide hanami | High | Medium (similar to tunnel) | None | None |
| petal shower | High | Medium | Yes (air + ground) | None |
| river sakura | Medium | Large (riverside composition) | None | None |
| long shot | Medium | Small (subject slightly smaller) | None | None |
| picnic | Medium | Large (sitting pose + props) | None | Clothing change (2/3) |
For cherry blossom expression in full-body shots, sakura tunnel has the largest effect on composition, stably achieving the avenue tunnel effect. petal shower is effective for scattering petal expression. river sakura can add a river as a background element. picnic adds props but clothing specifications tend to be ignored.
