                                    only works on the intensity of an image, 
                                    it can be combined with the other functions 
                                    in a graphics program to add more artistic 
                                    options to your graphics. The following 
                                    will show how an average photograph can

                                    image, the first thing to decide is how 
                                    you want the final sketch to look. If we 
                                    want a general sketch we will want strokes 
                                    covering the image. If we want a contrasted 
                                    sketch, we will want strokes only in the 
                                    areas we want to highlight. In this example 
                                    a contrasty sketch highlighting the red 
                                    hair is desired, so we'll need more/darker 
                                    strokes in areas of red. To get the right 
                                    source material, the image source intensity 
                                    needs to be processed in such a way to highlight 
                                    the material wanted. By using the companion 
                                    <b>PhotoGrey</b> plugin, selecting a slightly 
                                    green blue colour keeps the reds dark, producing 
                                    this source material...</p>

                                    <p align="left">This has kept the hair dark. 
                                    To increase contrast use the Histogram functions 
                                    or other image processing functions of your 
                                    graphics package...</p>

                                    <p align="left">Then convert it into a pencil 
                                    sketch using the Sketcher plugin. In this
