Nano banana 正火爆全球，谷歌立馬推出官方提示詞指南。
下面先進(jìn)行一些效果展示，看看它的強(qiáng)大之處。
借助 Nano-banana、Seedance 和 Kling，梵高、蒙娜麗莎、戴珍珠耳環(huán)的少女都能在紐約中央公園里合照。
不僅如此，還能生成十分炫酷的動(dòng)畫(huà)視頻。
甚至能毫無(wú)痕跡的換臉？！
好家伙，香蕉這波真是讓我開(kāi)眼了。感覺(jué)官方再不出教程，網(wǎng)友們自己都能搞個(gè)“百科全書(shū)”了。
正值香蕉熱度爆棚之際，谷歌總結(jié)其 5 大核心功能，助你輕松玩轉(zhuǎn)這一創(chuàng)新工具。
文本轉(zhuǎn)圖像：從文本描述生成高質(zhì)量圖像。
圖像 + 文本轉(zhuǎn)圖像（編輯）：可通過(guò)文本提示對(duì)圖像進(jìn)行添加、刪除或修改元素，還能改變風(fēng)格和調(diào)整色彩。
多圖像到圖像（構(gòu)圖和風(fēng)格轉(zhuǎn)換）：使用多張輸入圖像來(lái)組成一個(gè)新場(chǎng)景或?qū)L(fēng)格從一張圖像轉(zhuǎn)換到另一張圖像。
迭代細(xì)化：可通過(guò)多次對(duì)話(huà)逐步微調(diào)圖像，直至完美。
高保真文本渲染：準(zhǔn)確生成清晰且布局合理的文字圖像，適用于 logo、圖表和海報(bào)等。
谷歌還特別提示了，描述場(chǎng)景，不要僅僅列出關(guān)鍵詞。
相比簡(jiǎn)單、不連貫的關(guān)鍵詞列表，一段敘事性強(qiáng)、描述詳細(xì)的段落通常能生成更好、更連貫的圖像。
對(duì)于此指導(dǎo)，網(wǎng)友可謂十分喜歡。
下面讓我們一起看看具體提示詞是什么樣的。
6 類(lèi) Nano banana 提示詞
生成圖像最常見(jiàn)的方法，就是告訴它你想看什么。
先看看官方生成的圖片，貓貓?jiān)陔p子座星空下的豪華餐廳里吃香蕉。
哇哦，貓貓桌子上還擺著刀叉和酒杯，餐廳里其他桌子上也有客人，真是充滿(mǎn)了細(xì)節(jié)。
如果你也想用納米香蕉生成如此驚艷的效果，就一起來(lái)學(xué)學(xué)谷歌的 6 大類(lèi)提示詞吧。
逼真的場(chǎng)景
要獲得逼真的圖像，最好像攝影師一樣思考。提及相機(jī)角度、鏡頭類(lèi)型、光線(xiàn)和精細(xì)細(xì)節(jié)，這將使模型達(dá)到最逼真的效果。
通用提示如下所示：
A photorealistic [shot type] of [subject], [action or expression], set in [environment]. The scene is illuminated by [lighting description], creating a [mood] atmosphere. Captured with a [camera/lens details], emphasizing [key textures and details]. The image should be in a [aspect ratio] format.
不僅如此，谷歌還特意給出了 API 代碼。
