From version 4, this model includes training data, so I'm switching it to trained model, instead of merge.
Initially built to create lifelike portraits of characters from the novel I'm working on, whose title is Endless, thus the name of the model.
This is a rather complex merge, and sadly I did not took notes.
Prompting
Example of prompt for a realistic image (replace {prompt} with your subject):
professional photograph {prompt} ((video grainyfilm)), natural cinematic lighting, ((professional photo highly defined)) realistic, best quality, photo-realistic 8k, best quality, masterpiece, realistic, photo-realistic
You can add more details using this lora which gives pretty good results: Detail Tweaker LoRA (细节调整LoRA)
Example of negative prompt for a realistic image:
(text, signature, watermark, logo, ux, ui:1.3), monochrome, (2D), (3D), ((camera)), ((cartoony)), (CGI), ((drawing)), ((lowres)), ((painting)), ((sketchy)), ((The Sims)), (ugly), ((blur)) (worst quality, low quality, normal quality:1.3), lowres
NSFW content is possible, nsfw, uncensored in the negative prompt can help get rid of them.
More tips on prompting
You can actually use negative weights on lora/lycoris. Here is an obvious example with Microwaist Lora:
Using this, you can use Sharpness Tweaker LoRA (锐度调整LoRA) to lower the sharpness of the image, resulting in a somewhat more realistic picture as if it had been taken by an old camera. Here is an example showing the effect on girls of various ethnicities:
