About Nano Banana Pro

有些图片的难点不在风格,而在同时满足很多要求:商品要放对位置,人物与道具要有合理关系,标题还要清晰地融入版面。Nano Banana Pro 基于 Gemini 3 Pro Image 家族,强调复杂指令理解、推理辅助设计、文字呈现与高保真编辑,适合需要认真组织信息的视觉创作。

先安排画面,再丰富细节

可以从文字直接创作,也可以结合参考图指定主体、场景和风格。制作商品合成时,先说明产品位置、光线方向和透视关系;制作信息海报时,则把标题、内容层级和阅读顺序说清楚。把每个元素为什么出现在那里讲明白,通常比堆砌风格词更能帮助模型完成复杂画面。

用已有素材继续推进设计

参考图编辑适合把商品放进新环境、延续人物形象,或对一张接近完成的设计做调整。比如将平拍的家居产品融入真实房间,或者保留人物与服装,只改变背景和海报布局。多张参考图最好分别承担主体、构图或色彩的作用,避免互相矛盾。

支持 4K 级输出,适合需要较清晰展示的品牌视觉、封面、商品宣传图和提案。较高分辨率有助于呈现细节,却不能自动保证文字内容、商标和精细结构正确。长段文字、复杂图表与真实产品外观,应在发布前对照检查;局部编辑时,明确保留范围并逐步调整,能更容易延续满意的部分。

Use cases and prompting

用产品图做一张家居品牌海报

图一提供落地灯的外观,图二只参考客厅的配色。保持灯罩、支架和底座结构,把灯放在沙发左侧,暖色灯光照亮阅读角。竖版海报,上方只写“留一盏灯给自己”,下方留白。透视自然,房间简洁,不出现其他灯具和品牌。

先确认灯具结构与光线,再调整标题和整体色调。

复杂画面怎样写得清楚? 按主体、空间关系、文字、光线的顺序说明,给每张参考图分配用途。

文字很多能一次完成吗? 短标题和清晰层级更容易把握,密集正文建议后期排版。

4K 能解决所有细节问题吗? 分辨率决定清晰程度,细节正确性仍需要检查,尤其是商品结构与标识。
