Face A-detailer from 0% to 85%

Face A-detailer from 0% to 85%

I would recommend using face image-to-image from 40% to 60%. It's not really visible in the example images below but going above 60% can cause issues in the overall coherence and blending of the image.

It's generally not worth going above 40% denoise if your final image is being output at around 1024x1024 or 832x1216 resolution. The extra detail gained from a high denoise setting will mostly be lost to blur when the mixed pixel density image is downscaled. This is why you'll notice a significant difference in detail for the first set of images, but not the second. The difference between 40% and 60% denoise is much more pronounced in mixed pixel density images. I would have uploaded the 4983x4983 mixed pixel density images, but at 25MB per image, they exceed the 5MB per image limit.

Settings for initial image and face image-to-image.
Model: Real Dream 11 Lightning (8-bit)
Image size: 1024x1024
Steps: 12
Guidance: 2
Sampler: DPM++ 2M Trailing (Trailing = SGM Uniform)
Mask Blur: 15

10% strength is the same as 0.1 denoise.

Fortunately, Civitai offers a similar feature. At the top of your screen, click the blue "Create" button, which will open a sidebar on the left. In the top left corner, under 'Workflow,' change 'Text-to-image' to 'Text-to-image Face Fix.' Next, scroll down in the sidebar to the 'Advanced' section, where you'll find a new option called 'Denoise.' This setting functions like the 'Strength' option mentioned in the article. Set the 'Denoise' value to around 0.4 to 0.5.
