Test setup
- Resolution: 2K
- Aspect ratio: 1:1 for most tests (Test 5 uses 3:4 for a poster layout)
- Watermark: false
- Outputs: 1 image per prompt
Test 1: Typography on a sign
Prompt: High-resolution photo of a storefront sign on a brick wall. The sign is white with black lettering. The exact text must read: SEEDREAM V4.5. Clean sans serif. Centered. Natural daylight. Generate 1 image.
This test checks clean letter shapes and alignment. The result holds a convincing sign look. Small spacing can still drift when zoomed in.

Test 2: Product photo + label text
Prompt: Studio product photo of a clear glass perfume bottle on a marble surface. The label has the exact text: AURORA NO. 7. Minimal design. Soft shadows. 85mm lens. Generate 1 image.
Glass, reflections, and soft shadows look solid. The label layout reads well at a glance. Tiny text can wobble if the prompt adds extra branding details.

Test 3: Simple spatial control (three objects)
Prompt: Photoreal kitchen counter scene. Place a red apple on the left, a blue mug in the center, and a yellow lemon on the right. Soft window light. Sharp focus. Generate 1 image.
This test checks basic prompt adherence. When objects swap, stronger anchors help. Words like left edge and right edge usually tighten it up.

Test 4: Portrait lighting control
Prompt: Photoreal close-up portrait of a man with curly hair and round glasses. Warm key light from left, cool rim light from right. Natural skin texture. Background bokeh. 50mm lens. Generate 1 image.
Lighting direction cues work best when the prompt stays simple. This output keeps a clear warm and cool split. Background clutter stays low.

Test 5: Poster layout with dense text
Prompt: Minimalist art exhibition poster on an off-white background. A black line drawing of a human portrait slightly right of center. The title at top left in serif font must read: URBAN LINES. Under it, a smaller italic subtitle must read: SPRING SHOW. At bottom left, three tiny lines must read: APR 10-28, DOCK GALLERY, FREE ENTRY. Clean layout, strong typographic hierarchy. Generate 1 image.
This test targets layout and typography. Posters fail fast when the model loses hierarchy. Seedream tends to do well when the prompt lists exact lines and placements.

Test 6: Surreal illustration (composition and mood)
Prompt: Surreal illustration of a giant whale floating above a calm desert at sunrise. Long shadows on sand dunes. Pastel sky with thin clouds. Ultra-detailed, cinematic composition. Generate 1 image.
This checks composition and mood. The scene stays readable with a clear subject. Extra style words are not needed here.
