ArtSketch automatically turns images on your iPad into rough pencil sketches. Use the Shade toolbar button to adjust the brightness of the sketch, or other toolbar buttons to access built in shade settings. ArtSketch has full access to your iPad's photo library and allows you to save your sketch images to the library and send them as email attachments. ArtSketch also provides an aging function, accessed from the toolbar, to allow you to give your sketches a sepia look too.
