What do you mean by "proper"? What would be the difference between a proper and an improper sketching photo? — Andrzej Doyle, Aug 08 '12 at 09:53

Core Image filters are probably the best way to go, CILineOverlay and CIEdgeWork when blended together could give the effect you are after. http://developer.apple.com/library/ios/#documentation/GraphicsImaging/Reference/CoreImageFilterReference/.
