あまり吟味してないから思い通りにいってないですが、とりあえずはこういう使い方でよかったのかな
ちなみに下記はプロンプト全文です

Ultra-realistic live-action fantasy film still, grounded cinematic realism.
A medieval adventurer party stands in the foreground, fully integrated into the environment.

Color & Atmosphere (CRITICAL):
• Muted, desaturated palette shared by characters and environment
• Neutral overcast daylight
• Lifted blacks, no pure black
• Soft contrast, gentle tonal roll-off
• No warm cinematic lighting
• Fabrics faded, damp, travel-worn
• Skin tones subdued, weathered

A thin layer of mist and humidity affects all elements equally, slightly softening edges.
⸻
Foreground – Adventurer Party
The party moves as a single unit, paused mid-advance.
• The leader raises one hand, actively invoking a search spell
• Other members focus in the same direction, tense and alert
• No heroic spotlighting
• Armor and weapons dulled, matte, non-reflective
• They share the same air, grime, and light as the environment
⸻
Background – Abandoned Mycal Honmoku
The recognizable plaza remains intact:
• Central fountain with stagnant water
• Tiled ground cracked with moss
• Glass walkways and railings partially overtaken by vines
• The space is silent, abandoned, oppressive
⸻
Post-Effect – Search Magic (AMPLIFIED EXPERIMENTAL STATE)
Search magic is represented exclusively as a post-effect layer.
Numerous extremely small luminous cross-shaped light markers
(X-axis and Y-axis only; no diagonal rays)
are densely distributed throughout the environment.

Intensity & Distribution:
• Significantly increased quantity compared to subtle mode
• Foreground markers appear larger and more defined
• Midground markers medium-sized
• Background markers extremely small, almost noise-like
• Clear depth-based scaling from near to far

Spatial Bias:
• Concentrated along architectural edges:
walls, pillars, glass frames, railings
• Highlight floor cracks, tile seams, broken edges
• Trace depth boundaries and spatial discontinuities
• Avoid direct overlap with character silhouettes
• Always biased toward background surfaces

Behavior:
• Markers subtly flicker and pulse irregularly
• No rhythmic animation, no symmetry
• They feel like perception artifacts, not light sources

Green Outline Layer:
• Thin, unstable green vector-like contour lines intermittently trace
building edges, structural corners, and object silhouettes
• Lines appear fragmented, jittering, partially incomplete
• They do not fully outline objects, only suggest detection
• No glow, no bloom, no neon intensity

Constraints:
• No new light sources
• No illumination changes
• No glow, bloom, or lens flare
• No change to shadows, contrast, or exposure
• Effects exist only as perceptual overlays
⸻
Film Texture
• Natural film grain
• Slight atmospheric haze
• Subtle motion blur acceptable
• No digital sharpness
• Live-action cinematic realism only
⸻
Subtitle (Japanese)
Add a subtle cinematic subtitle at the bottom of the frame:

…人の気配がしないな

• Small, understated
• Film-style subtitle
• No modern UI
• Feels like a quiet line spoken under breath
⸻
The search magic effect must be applied strictly as a post-effect.
It must not introduce any new light sources, glow, or illumination.
It must not alter existing lighting, shadows, contrast, or color grading.
Generate the image strictly according to the above description.
