Seedream 4.0 Powered By ByteDance

Use Cases
Artistic Portrait Photography
Transform the above image into a top-tier portrait shot taken in a photography studio, requiring a half-body shot with coordinated and natural movements, close-up shot, focusing on the face. The subject's clothing and gestures should be changed to urban casual style, with an overall atmosphere leaning towards profound but not deliberate. The overall effect is quiet, profound, and gentle. The background presents a soft gradient effect, creating a sense of depth and serene atmosphere. The delicate film grain texture adds a tactile, analog photography-like soft quality to the image, reminiscent of classic black and white photography. A gentle directional light, softly diffused, caresses the contours of the subject's cheeks, or creates catchlights in the eyes—this is the emotional core of the image. The rest is occupied by a large amount of negative space, deliberately kept minimal, allowing the image to breathe freely. There is no text or logos in the frame—only the interweaving of light, shadow, and emotion. Top photographer's portrait style, off-center composition.
