Some time ago practicing image to image with one of my models I could see that they had the high ability to be able to generate realistic images from anime images, something very useful when you want to imagine how that animated image would look realistically, in the same way I want to take the opportunity to show the other side that we can also do by turning realistic images into excellent anime images.
I recommend the following two models that have given me excellent results, one to convert anime to realistic and the other to convert realistic images to anime:
SatPony - SatPonyV3 Realism! | Stable Diffusion Checkpoint | Civitai
SatPony-ComiX - SatPony-ComiX | Stable Diffusion Checkpoint | Civitai
The proofs are made in Forge but the same applies to A1111
The parameters are as follows:
In the Img2img tab you have to place the image you want to convert
Resize mode: Jus resize
Sampling Method: Euler A SGM Uniform if you want Anime or DPM++ 2M SDE Karras if you want realism
Resize to the same scale or if its a low pixel image try to resize at least double
CFG Scale: 5
Denoising Strength: i recomend 5.5 but you can try in a range from 5 to 6.5
If you have the prompt and the seed try to use them, if you don't have them it will be enough to make a brief description of the image in the prompt.
Real to anime:
