Adobe Photoshop is the best software you can use to obtain line drawings from photos in just a few minutes. Open your picture with Adobe Photoshop, duplicate the background layer and hit Ctrl+D to change the foreground color to black. From the top menu, choose Filter, Other and High pass and select a small radius, like 0.3. Again, from the top menu, choose Filter, Sketch and Note Paper. Reset Graininess and Relief to zero and the Image Balance to 20. From the Image menu, hit Adjustments and Threshold and adjust the settings until you obtain a black and white image. Take the Pencil tool and reset the foreground color to white, by pressing X. Correct the damaged pixels with the help of your pencil.
