Watercolor is a Windows and Mac Photoshop plugin and application that lets you experiment with a wide range of watercolor painting genres: from marine paintings and atmospheric landscapes up to human or animal portraits and still lifes. Adjust the watercolor effect settings in the Painting tab. You can choose one of the Presets or set the parameters to your liking. You can improve the result of the automatic conversion using the Stroke Direction tool. The standalone program supports JPEG, RAW, PNG, BMP, and TIFF file formats.
