如果提示词过短,比如之前的 "a young woman",更容易让 midjourney 倾向于绘画风格而非逼真照片。如果写一个非常详细的提示词,比如 "a young woman with shoulder length auburn hair, bright green eyes, light freckles across her nose, wearing a pink floral print dress, laughing joyfully (年轻女子,一头齐肩的赭色长发,一双翠绿色的眼睛,鼻子上有浅浅的雀斑,身穿粉色花卉印花连衣裙,开心地笑着)",就会产生更逼真的效果,如下图所示:
4. 使用 raw 模式
使用 raw 模式或是添加参数 "--style raw" 也会产生更逼真的效果。比如上面的提示词添加了这个参数以后,效果如下
prompt: double exposure of a yogi in a meditation pose and a galaxy, aiming for spiritual transcendence, white background, by dan hillier --s 750 --style raw (冥想姿势的瑜伽者和银河系的双重曝光,旨在实现精神超越,白色背景,作者:dan hillier)
在某些情况下,混合不同的风格会产生令人着迷的图像。
prompt: fusion of fashion and surreal photography - a model floats wearing a flowing gown that morphs into clouds --s 750 --style raw (时尚与超现实摄影的融合--模特身着飘逸的礼服,幻化成云朵)
prompt: a young east asian woman with straight black hair, almond shaped eyes, cherry red lips, wearing a jade green cheongsam and vintage shoes, standing elegantly, portrait by annie leibovitz --ar 2:3 --s 750 --style raw (一位年轻的东亚女性,黑色直发,杏眼,樱桃红唇,身着翠绿色旗袍,脚穿复古鞋,优雅站立,肖像摄影师:安妮-莱博维茨)
prompt: a young japanese woman with chin length black hair, warm brown eyes, rosy cheeks, wearing a kimono, feeling tranquil, under a cherry blossom tree, rembrandt lighting --ar 2:3 --s 750 --style raw (一位年轻的日本女性,下巴长的黑发,温暖的棕色眼睛,红润的脸颊,身着和服,在樱花树下感受宁静,伦勃朗照明)
prompt: a young woman with long chestnut waves, almond eyes, wearing a boho dress, looking carefree and adventurous, walking barefoot on the beach at sunset, golden hour lighting --ar 2:3 --s 750 --style raw (栗色长发、杏仁眼、黝黑皮肤的年轻女子,身着波西米亚风连衣裙,看起来无忧无虑,充满冒险精神,赤脚走在夕阳西下的海滩上,金色的夕阳映照在她的脸上。)
prompt: ballerina mid-leap, sunbeam spotlighting her form, elegant pose, soft tulle skirt, stark contrast with dark background, artistic portrait --s 750 --style raw (芭蕾舞演员正在跳跃,阳光照亮了她的身形,优雅的姿势,柔软的薄纱裙,与深色背景形成鲜明对比,艺术肖像)
戏剧性的灯光甚至还可以强化抽象摄影,突出纹理和材质。
prompt: black and white abstract photography, in the style of layered translucency, flowing fabrics, translucent overlapping, abstract watercolor, haunting structures, backlit accenting the texture --s 750 --style raw (黑白抽象摄影,采用层叠半透明、流动织物、半透明重叠、抽象水彩、萦绕结构的风格,背光突出质感)
prompt: disposable camera photo of a little girl blowing a dandelion, backlit by the sun, individual seeds caught in soft focus, innocence captured --s 200 --style raw (用一次性相机拍摄的小女孩吹蒲公英的照片,在阳光的映衬下,单粒种子被柔焦捕捉,纯真之情尽收眼底)
哈苏 x1d 中画幅相机则带来超高分辨率和色调。
prompt: vintage car parked on a cobblestone street, worn paint and rust details, hasselblad x1d --s 750 --style raw (停在鹅卵石街道上的老爷车,磨损的车漆和生锈的细节,哈苏 x1d)
除了相机之外,还可以添加胶片,赋予照片永恒的魅力。例如 ilford hp5 plus 可以赋予照片更加细腻的纹理。
prompt: side view of a racing greyhound, frozen in full stride, harsh lighting highlighting muscles and motion, robust thighs, elongated legs, ilford hp5 plus --s 750 --style raw --ar 16:9 (赛跑灰狗的侧影,凝固的全速前进,刺眼的灯光突出肌肉和运动,健壮的大腿,修长的腿,ilford hp5 plus)
特殊的镜头也能赋予照片独特的风格。例如,鱼眼镜头可以捕捉小宝宝夸张的表情。
prompt: fisheye lens captures a crazy baby --s 750 --style raw (鱼眼镜头拍摄一个疯狂的宝宝)
prompt: lensbaby shot of young woman in a meadow, swirling bokeh background, ethereal lighting casting soft shadows on her face, dreamlike atmosphere --s 750 --style raw (lensbaby 拍摄草地上的年轻女子,漩涡虚化背景,空灵的光线在她脸上投下柔和的阴影,梦幻般的氛围)

4. 改变相机的角度和景别
借助 midjourney,我们可以引导 ai 的虚拟之眼,指示它从不同的位置、距离和视角捕捉场景。
prompt: extreme low angle view of bride in her wedding dress, train trailing behind her, backlit to create an ethereal silhouette, emphasis on the grandeur of the gown, nikon 14-24mm f2.8 --s 750 --style raw --ar 16:9 (极低角度拍摄身着婚纱的新娘,裙裾拖在身后,逆光营造出空灵的轮廓,强调婚纱的华丽,尼康 14-24mm f2.8)
prompt: extra wide shot of sunset over the grand canyon, golden light illuminating every ridge and crevice, broad shadows adding depth, expansive sky filled with wispy clouds --ar 16:9 --s 750 --style raw (大峡谷日落的超广角镜头,金色的光线照亮了每一个山脊和缝隙,宽阔的阴影增加了深度,广阔的天空飘满了飘渺的云朵)
