From Wondershare Software:
PowerSketch is a fascinating yet easy-to-use app that brings out the Picasso in you. 10+ realistic and creative sketch effects come standard with PowerSketch, including rice paper, picture-in-picture, shadow, wash, neon, and more. You can capture an image and turn it into a sketch or select an image from your camera roll or gallery to convert to a sketch. Select an effect you like before capturing, not only your photo, but also video becomes an artwork immediately with a live preview of what the final one will look like. Want to apply these cool effects to the photos in the camera roll? No problem. Tap to enter the Edit mode in the homepage, and you're ready to choose the photo and apply sketch effects. Combine the sketched photos to create awesome photo collages if you want. Tap, tap, tap to change layout and frames, the process is already fun enough. When you're done, share with your friends and family on YouTube, Facebook, Twitter, Flickr, Tumblr, or email with one tap only. Things haven't been so easy before.
