Portrait — Side-by-Side Results
Prompt
"Portrait photo of a 20s woman with shoulder-length wavy dark hair in a cozy oversized hoodie and minimal makeup, holding her phone slightly out for a casual selfie while glancing near the camera with a relaxed half-smile. She’s sitting at a small neighborhood café table with an iced latte and an open laptop, warm window light on her face, shallow depth of field with soft bokeh from the background patrons (85mm lens feel). Natural, candid Instagram-story vibe—slightly imperfect framing, real-life clutter, authentic expression."

- Up to 4K output for portraits that need tight crops, print-ready detail, or high-res retouch-friendly delivery
- Flexible resolution pricing (1K/2K at 22 credits; 4K at 44 credits) for choosing between speed and maximum detail
Seedream 4.5 Strengths
- Best choice when you need <strong>image-to-image editing</strong> to refine a portrait (adjust background, styling, lighting mood, or composition from an existing image)
- Versatile styles for portraits—easy shifts between editorial, lifestyle, cinematic, and more stylized looks
- Strong overall portrait quality at a predictable per-image cost (16 credits) for quick iteration

Verdict
Pick Nano Banana Pro when you want production-quality portraits with maximum clarity—especially for close-up headshots, campaign-ready polish, and any portrait concept that includes readable text elements within the image. It’s also the better fit when you expect to crop aggressively or deliver high-resolution finals (up to 4K).
Pick Seedream 4.5 when your portrait workflow depends on editing—starting from an existing image and iterating toward the final look. For environmental portraits in particular, its image-to-image flexibility can save time and credits by refining what you already like rather than regenerating from scratch.
