Mixed-lighting prompt test: Seedream 5.5 leans ambient, MiniMax H3-Image goes harsh flash

The author ran the same 4:5 prompt — a family of three crouching on a gravel path at dusk greeting their leaping dog, with faint sunset glow, harsh on-camera flash, near-black background, sharp shadows, red-eye, motion blur and film grain — through two image models.
- Seedream 5.5: strong fine texture (accurate plaid work shirt, natural tilted frame) but prioritized the warm ambient light, reading more like fill flash and leaving the background un-darkened
- MiniMax H3-Image: firmly executed the harsh flash falloff, pushing the background near pure black so the pale yellow slip dress and red overalls pop — closer to the punchy snapshot look intended
The author shared a real-photo-style reference and asks whether others see consistent flash behavior with mixed-lighting prompts.
