这个lora想做出理想的效果，需要在使用之前看一下我的说明，非常感谢您的耐心阅读。

重要的事情说三遍：不要把证件照lora和人物lora直接叠在提示词栏中使用，不要把证件照lora和人物lora直接叠在提示词栏中使用，不要把证件照lora和人物lora直接叠在提示词栏中使用。

使用证件照lora的最佳方案是：先用权重使用adetailer插件换脸

（1）你已经有了一个面部相似度比较高的人脸lora，但不要把它放入提示词栏，提示词栏的lora只放证件照，权重为1（一定要开高权重）；

（2）使用majicmixrealistic v6作为底模，采样方式DPM++ 2M SDE Karras，步数30或更高以上，CFGscale7，记得开高清修复，生成一张不错的证件照底图；

（3）正面提示词举例：identification photo,1 girl,long hair,bangs,looking at viewer,(white shirt,blue tie,red background:1.3),happy,smile,负面提示词自己写，底色可以换成white/blue/grey background；

（4）打开adetailer插件，模型选择face，Adetailer prompt中放入你的人脸lora，格式为<lora:人物:权重>，权重建议0.75以上

证件照lora的微调优化方案：

（1）如何区分底色和衣服颜色：

如果你遇到背景和人物衣服总是同色的情况，推荐使用防染色神器cutoff插件，比如我希望得到“白衬衫、蓝领带、红底色”的照片，在Target tokens中输入(white shirt,blue tie,red background),weight拉到2

（2）如何调整底板人物的脸型：

如果你使用adetailer换脸后发现，“五官相似度可以，但脸型不太吻合”

这个lora不会干扰画面构图，可以和证件照lora一同加入正面提示词栏，权重范围是-1.5（瓜子脸）到1.5（小圆脸）；

（3）男生出图像女生怎么办？

我可以明确告诉你，这是SD的通病，你可以试着换成比较擅长生成男生的底模，这可不仅仅是lora的问题，众所周知SD所有训练素材中女生远大于男生。

要出男生的底图记得多打tag，比如(1 boy,male focu:1.3)，权重多调试

如果只有一张照片怎么办？

麻烦你用PS或者美图秀秀，不要用SD，做这个lora的初衷不是为了实现一张图换脸；

非要用SD的ROOP插件，脸部相似度无法保证，这是ROOP模型的问题，不是Lora的问题。

To achieve the desired results with this LoRa, it's important to review my instructions before usage. Thank you very much for your patient reading.

Important matters stated three times: Do not directly overlay ID-photo LoRa and character LoRa in the prompt section. Do not directly overlay ID-photo LoRa and character LoRa in the prompt section. Do not directly overlay ID-photo LoRa and character LoRa in the prompt section.

The optimal approach for using ID-photo LoRa is as follows: Begin by using weights to apply the adetailer plugin for facial replacement.

(1) You already have a facial LoRa with relatively high similarity, but do not place it in the prompt section. The LoRa in the prompt section should only feature the ID-photo, with a weight of 1 (ensure a high weight setting). (2) Utilize majicmixrealistic v6 as the base model, using DPM++ 2M SDE Karras sampling method, with 30 or more steps, CFGscale7. Remember to activate high-definition repair for generating a good base image for the ID-photo. (3) For frontal prompts: identification photo, 1 girl, long hair, bangs, looking at the viewer, (white shirt, blue tie, red background: 1.3), happy, smile. Negative prompts can be self-created. Background color can be changed to white/blue/grey. (4) Open the adetailer plugin, choose the face model, and input your facial LoRa into the Adetailer prompt in the format <LoRa: character: weight>, with a recommended weight of 0.75 or higher.

Fine-Tuning Optimization Plan for ID Photo Lora:

(1) Distinguishing Background and Clothing Colors: If you encounter situations where the background and the person's clothing are always of the same color, it is recommended to use the anti-staining tool, the 'cutoff' plugin. For example, if I want to achieve a photo with "white shirt, blue tie, red background," input (white shirt, blue tie, red background) in the Target tokens and set the weight to 2.

(2) Adjusting Facial Shape of Subject against Background: If you find that after using 'adetailer' for face swapping, the 'facial features match but not the face shape,' I recommend you download the 'Muggle Lora' facial shape adjustment tool from https://www.esheep.com/model/1569. This Lora tool won't interfere with the composition of the image. It can be combined with the ID photo Lora and added to the frontal prompts. The weight range is from -1.5 (oval face) to 1.5 (round face).

(3) Generating a Female Image from a Male Subject: I can clearly tell you that this is a common issue with SD (Style-DALI). You can try using a base model that is more skilled at generating male subjects. This is not just a Lora-specific problem; it's widely known that SD's training data is skewed towards females. When generating a male base image, remember to use relevant tags like (1 boy, male focus: 1.3) and fine-tune the weights.

What to Do If You Only Have One Photo? Please use Photoshop or apps like Meitu Xiuxiu; avoid using SD. The original intention of using Lora is not for simple face swapping with a single image. If you insist on using SD's ROOP plugin, facial similarity cannot be guaranteed due to issues with the ROOP model, not Lora's model."
