Painting & Sketch Photoshop Actions 700388 Make your photos look like paintings / illustrations and sketches with these two amazing Photoshop Actions. Take a look at the examples to see how they work with different types of images. You can apply the effects to any size images. For a strong effect images that are around 2000px on their longest side work particularly well with a single run of the Painting Action, while higher resolution shots require two passes. For the Sketch Action a single pass is enough regardless of image size. You can apply the effect to any image, but those with a lot of texture and detail work best.
