The Oil Paint filter turns a photo into a quasi oil painting. You can’t vary the size or direction of the brush strokes in different parts of the image, but it does produce some rich textural effects.
Under Brush and Lighting, adjust the sliders:
Stylization controls the smoothness of the strokes.
Cleanliness controls the purity of (amount of color variegation in) the colors.
Scale controls the width of the strokes.
Bristle Detail controls the visibility of bristle marks in the paint strokes.
Angular Direction controls the position of the highlights on the paint surface.
Shine controls the intensity of highlight reflections on the paint surface. This slider has a strong impact.
Thanks
