You can create your own styles, but these are built in to get you started:
A refined version of the original Painteresque. It uses a softer approach that is a little bit cleaner in smooth areas such as skin or sky, but may not pull out the sharpest details quite as well.
Creates a simple print effect in a vintage color scheme reminiscent of old posters.
Provides a light, sketch effect in muted color. Fine-tuning the brightness (Grey Shift) can find the sweet spot for any particular image.
A black and white sketch effect.
A fun style that punches up the color for a whimsical storybook effect.
Plays with colors to create an other-worldly mood.
Selectively softens the image for an airbrush feel without blurring sharp edges.
The original Painteresque.
Produces the original image unchanged. This is a useful starting point if you want to create a custom Style from scratch.
