Photoshop CS6 Tutorial
How to Add an Oil Paint Effect in Photoshop
One of the new additions to Photoshop CS6 is the Oil Paint filter. It allows you to quickly convert your photograph to an image similar to an oil painting.
Open an image in Photoshop (File > Open).
Our goal at this point is to simplify the image. Choose Image > Mode > Indexed Color.
Set the Dither to None and then adjust the Colors value so you have a strong base image. Click OK to accept your image.
Return to RGB mode by choosing Image > Mode > RGB Color.
Press Cmd/j (PC - Ctrl/j) to duplicate the Background layer.
With the upper layer selected in the Layers panel, choose Filter > Oil Paint.
In the Brush section, you can adjust the Stylization, Cleanliness, Scale and Bristle Detail. Higher Cleanliness values produce less detail in your image.
The Lighting section is used to set the light Direction and Shine. Raise the Shine value to accentuate the brush strokes.
Once you are finished with your adjustments, Press OK to accept your settings.
