Adds contrast, detail, and quality improvements to hires fix. Improves hands a bit. Gives more realistic skin textures on photorealistic models. (Scroll down to see another post with still comparisons of the animated images.)
Important generation notes:
In the example images, this LoRA was only enabled during the Hires Fix step. I've had very good results enabling it for both passes (in which case it makes generations more dramatic and vibrant), but it does alter composition somewhat, which makes direct comparison harder.
If you want to run this LoRA during your hires fix only, you can download this a1111 extension here:

...and add the LoRA to your positive prompt like this: <lora:EnvyBetterHiresFixXL01:0:hr=1>
(Or just add it like a normal LoRA to use it during both passes.)
