What Seedream 4.5 does well

Natural-light portraits with true-to-life skin

Seedream 4.5 renders people with true-to-life skin tones and soft, believable light.

In the sample, a teenage boy in a pale yellow rain jacket stands on a pebble beach under an overcast sky.

The sea falls into soft focus, rain droplets sit on the jacket, and his expression reads as a shy half-smile rather than a posed grin.

Name the light and the weather, the lens, and where the subject sits in the frame. Keep the styling short so the face stays the focus.

A natural-light portrait of a teenage boy with wind-tousled hair and a pale yellow rain jacket, standing on a pebble beach under soft overcast light. Grey-blue sea and sky behind in soft focus, true-to-life skin tones, a slight shy smile, rain droplets on his jacket. Horizontal composition with the subject on the right third, 85mm lens.

Styled from multiple reference images

This is where ByteDance's consistency claim pays off. The sample pairs a board of references, including rust corduroy, cream wool, olive silk, paint chips and a gold hoop earring, with a portrait of a woman wearing all of them.

Seedream 4.5 identifies the target element in each input image, so you can say which reference is the jacket, which is the scarf and which is the jewellery.

Upload a face photo as well when the same person should appear in every look.

A styling presentation on a pale oat background. Left side: a neat collage of references — three fabric swatches in rust corduroy, cream wool and olive silk, four paint color chips, and a photo of a chunky gold hoop earring. Right side: a portrait of a woman wearing a rust corduroy jacket over a cream wool top, an olive silk scarf and gold hoops, matching every reference, photographed in soft window light. Editorial fashion layout, no text.

A consistent batch for catalogues and social grids

Seedream 4.5 can return several images from one run that read as a single shoot. The four mugs in the sample come in oat, sage, clay pink and slate blue glazes.

The camera angle, the window light, the linen surface and the sprig of dried grass repeat in every tile, with the same colour grading and shadow direction.

Describe the shared setup once, then list what changes from image to image. It suits catalogue pages and social grids, where one mismatched tile stands out.

A two-by-two grid of four product photographs that belong to one consistent set: four handmade ceramic mugs in oat, sage, clay pink and slate blue glazes. Every tile uses the same camera angle, the same soft window light from the left, the same pale linen surface and a single sprig of dried grass beside each mug. Consistent color grading and shadow direction across all four tiles, catalog photography.

How to write prompts for Seedream 4.5

1. Seedream 4.5 prompts with several references should say which upload is which: "image 1 is her face, image 2 is the jacket fabric, image 3 is the earring".

2. Describe light in photographic terms (overcast sky, north window, backlit golden hour) and say where it comes from.

3. For a set, write the shared setup first and the per-image change last, such as "same angle and light; glaze colour changes: oat, sage, clay pink, slate blue".

4. Ask for natural skin texture and a lens length such as 85mm when you want a portrait that does not look retouched.

5. Keep each edit to one change: remove one person, swap one material or translate one sign per prompt.

Sample prompts to try with Seedream 4.5

• 

  Portrait by the window

  A close natural-light portrait of a man in his sixties with sun freckles, short white beard and kind eyes, wearing a grey ribbed knit sweater. Soft diffused window light from the left, plain warm grey wall behind, natural skin texture with fine wrinkles, quiet expression. Square composition, 85mm lens, understated editorial portrait.

• 

  Linen shirt in a wheat field

  A young woman with windswept dark curly hair and a loose white linen shirt standing waist-deep in a golden wheat field in late afternoon. Backlit sun creates a soft halo on her hair and the wheat tips, gentle lens flare, her hand brushing the stalks, relaxed candid expression. Warm natural tones, 85mm lens, shallow depth of field.

• 

  Friends at a kitchen table

  Two friends in their twenties laughing together at a scrubbed wooden kitchen table in the morning, one holding a coffee cup with both hands, the other mid-gesture telling a story. A bowl of clementines, a linen tablecloth, soft window light from behind with gentle flare, pale sage walls. Candid lifestyle photography, natural skin tones, 35mm lens.

• 

  Dancer in a sunlit studio

  A contemporary dancer in a simple grey leotard stretching on the wooden floor of an empty rehearsal studio. Long stripes of morning sunlight from tall windows fall across the floor and her body, dust in the air, a wooden barre along the wall. Calm, graceful, vertical composition from slightly above, natural tones.

Seedream 4.5 limitations

• Consistency follows what you upload. A blurry or harshly lit reference photo passes its flaws into the result, so use a clear, evenly lit image of each face or product.

  If your only photo of someone is old or damaged, clean it up first with AI photo restoration.

• Small text is better than on Seedream 4.0 but still needs proofreading.

  The model also does not plan a layout from the purpose of a brief the way Seedream 5.0 Lite and Pro do, so give every text element an explicit position.

• Hands, and people far from the camera, can lose detail in group shots. Keep the people who matter large in the frame and regenerate images where fingers or background faces look wrong.
