The key to great Seedream 4.5 results is detailed prompting. Be specific about subject, style, mood, lighting, composition, and camera angle — “close-up cinematic portrait of a woman at golden hour, warm rim light, shallow depth of field” works better than “a portrait of a woman.” Experiment with different descriptions, reference images, and stylistic cues until you find what works best for your vision.
