造梦师手记:AI还原真实胶片摄影

今天推荐一个高度接近胶片风格的Flux模型:TruBass


作者在C站称:

由于这是一个 FLUX DEV 模型,根据使用和自定义模型的许可协议,必须声明对其所做的所有更改。

在这种情况下,可以总结如下:

我们使用自己的标注风格为 Mile High Styler 训练了约 1000 种风格到模型中。

然后我们测试了 1000 多种风格,并确定了哪些风格存在不足。

我们使用模型自身的输出来创建合成数据集,这些数据集反映了每种风格中最严重的错误。

我们使用这些不良数据集逐个训练了单独的“坏”LORA。

接着,我们收集并整理了一个小型真实数据集,用于训练“好”LORA。

“坏”LORA 用于负权重以去除不需要的元素,而“好”LORA 则用于恢复模型失去的部分权重,并更准确地塑造出预期的风格输出。

然后将正负权重 LORA 的组合与模型合并,并保存为检查点。

我们每天重复这个过程多次,持续了大约 3 个月。期间我们定期合并我们的工作,并偶尔结合其他社区模型,如 ShuttleDiffusion、Crystal Clear Super、Jibmix 和 ArtsyDream,以增加上下文。

当我们与社区模型合并时,必须重新应用负权重 LORA,以避免在合并过程中丢失我们已有的进展。

在某些情况下,还需要重新应用正权重 LORA。

该模型的目的是创建一个替代 FLUX DEV 模型的版本,使其在大多数情况下不再需要额外的 LORA。我们本希望将角色(包括名人)添加到模型中,但从根本上说,这似乎超出了我们作为简单模型合并 LORA 训练者的能力范围。

尽管整个过程看似简单,但这确实是一项极其困难的任务。大部分困难来自于研究部分,以及开发一种系统,使模型能够在不同数据集上以相同的参数进行一致训练。由于模型架构要么无法修复,要么需要从头彻底改造,我们不得不做出一些妥协。

【都市时尚与艺术交融】


(图片中,一个人站在一幅色彩斑斓的抽象画前。此人穿着一件鲜艳的单肩连体裤,设计宽松流畅。连体裤上装饰着各种明亮的抽象图案,色彩包括橙色、蓝色、绿色和紫色。背景画同样鲜艳,蓝色、黄色、粉色和黑色的漩涡图案营造出一种迷幻效果。场景似乎是一个城市环境,地面是磨损的水泥地。)


The image features a person standing in front of a colorful, abstract painting. The person is wearing a vibrant, one-shoulder jumpsuit with a flowing, wide-legged design. The jumpsuit is adorned with a variety of bright, abstract patterns in shades of orange, blue, green, and purple. The background painting is equally vivid, with swirling patterns in blue, yellow, pink, and black, creating a psychedelic effect. The setting appears to be an urban environment with a worn, concrete floor.

.【人物肖像】


【图像描绘了一位拥有长而卷曲的棕色头发的人。这个人穿着一件带有花卉图案的无肩带服装。背景似乎是一面中性色调的浅色墙壁。光线柔和,突出了人物的肤色和头发的质感。】


The image depicts a person with long, wavy brown hair. The individual is wearing a strapless garment with a floral pattern. The background appears to be a neutral, light-colored wall. The lighting is soft, highlighting the person’s skin tone and the texture of their hair.

.长城上的花影


(图片描绘了一位身着传统花卉图案连衣裙的女子,站在一条石径上,这条石径似乎是长城的一部分。长城蜿蜒延伸至远方,穿过郁郁葱葱的丘陵和山脉。长城由石头和砖块建造,沿途可见间隔分布的瞭望塔。女子身穿红色连衣裙,上面有精美的花卉图案,她的发型优雅,头戴花卉饰品。整个场景如画般美丽,将历史建筑与传统服饰融为一体。)


The image depicts a woman dressed in a traditional, floral-patterned dress standing on a stone pathway that appears to be part of the Great Wall of China. The Great Wall stretches into the distance, winding through the lush green hills and mountains. The structure is made of stone and brick, with watchtowers visible at intervals along the wall. The woman is wearing a red dress with intricate floral designs, and her hair is styled in an elegant manner, adorned with a floral accessory. The overall scene is picturesque, blending historical architecture with traditional attire.

.神秘森林中的黑裙女子


(图片展示了一个人站在森林区域。他们穿着一件长款黑色连衣裙,裙子的上身和袖子上有精美的蕾丝细节。裙子有一个合身的上身,心形领口和一条垂至地面的全裙。袖子宽大且呈喇叭形,为整体造型增添了戏剧性。这个人有着长长的黑发,戴着一条带有吊坠的项链。背景由茂密的绿色植物组成,营造出一种自然而神秘的氛围。)


The image shows a person standing in a forested area. They are wearing a long, black dress with intricate lace detailing on the bodice and sleeves. The dress has a fitted bodice with a sweetheart neckline and a full skirt that flows to the ground. The sleeves are wide and flared, adding a dramatic flair to the outfit. The person has long, dark hair and is wearing a necklace with a pendant. The background consists of lush green foliage, creating a natural and somewhat mysterious setting.

.【峡谷之巅的沉思者】


【这幅画面描绘了一个人站在岩石边缘,俯瞰着广阔的峡谷景观。这个人身穿蓝色花卉图案的连衣裙和凉鞋,背对着镜头。峡谷中呈现出多层岩石构造,色彩从棕色、红色到灰色不等,显示出不同的地质层次。地形崎岖,悬崖陡峭,山谷深邃。天空晴朗,几朵云彩点缀其中,暗示着阳光明媚的一天。整个场景传达出一种对大自然的敬畏和自然之美的感受,类似于国家公园或类似的自然奇观。】

The canyon features multiple layers of rock formations, with varying shades of brown, red, and gray, indicating different geological strata. The terrain is rugged, with steep cliffs and deep valleys. The sky above is clear with a few clouds, suggesting a sunny day. The overall scene conveys a sense of awe and natural beauty, typical of a national park or a similar natural wonder.

.都市夜景中的女子


(图片展示了一位女子夜晚站在海滨长廊上。她身穿黑色无袖连衣裙,长发披肩。她左手倚靠在栏杆上,面向镜头。她身后是一座灯火通明的高楼大厦,城市天际线上还有许多其他建筑,各种灯光闪烁。前景的水面倒映着建筑物的灯光,营造出充满活力的氛围。栏杆附近停泊着一艘船,船上挤满了欣赏风景的游客。整个场景展现了一个繁华的都市环境,可能是一个受欢迎的旅游目的地。)


The image shows a woman standing on a waterfront promenade at night. She is wearing a black, sleeveless dress and has long, dark hair. She is leaning on a railing with her left arm, looking towards the camera. Behind her, there is a large, illuminated skyscraper in a cityscape with numerous other buildings lit up with various lights. The water in the foreground reflects the lights from the buildings, creating a vibrant and lively atmosphere. There is also a boat docked near the railing, filled with people enjoying the view. The overall scene suggests a bustling, urban environment, possibly a popular tourist destination.

.古老石墙前的神秘身影


(图片中展示了一位长发披肩、身着深色服装的人物,服装上可见缝线和纽扣,风格可能为中世纪。此人背靠石墙而立,石墙似乎是古老或质朴建筑的一部分。整体色调偏暗且带有绿色调,营造出一种诡异或历史感的氛围。)


The image shows a person with long, dark hair, wearing a dark, possibly medieval-style, garment with visible stitching and buttons. The person is standing against a stone wall, which appears to be part of an old or rustic structure. The overall color tone of the image is muted and greenish, giving it a somewhat eerie or historical atmosphere.
