  • Max: The intensity of the final stylized effect is at its highest (more stylization).

Image Tips and Hacks

Number of images

• Using multiple but consistent images can create a more intense and fantastical effect with the same parameters.

  • Example:

    

Copy style of art

• To capture and stylize the effect with a specific vibe, you can also use images that embody the desired style, even if they don't feature characters. For instance, nature scenes or still life images can be effective. In such cases, use the cartoon preset and adjust the effect intensity. Setting the intensity to 1 will give you the most intense effect.

  • Example:

    

Quality

• Try to upload high-quality reference images. The quality of the image can highly influence the quality of the effect. For example: if the reference image is small and blurry, the effect may have unexpected results.

Effect with Low quality reference	Effect with High quality reference

Light

• Make sure the lighting on the picture is good. The skin color should look natural, the structure of the face visible. It`s better to not have any contrast shadows or artifacts on the face.

Challenging lighting	Simple lighting

Scale

• Try to make the face take up the 2/3 of the frame, the shoulders are not necessary but they can help with the scale of the head relative to the body.

Challenging Scale	Good Scale
