If you can't paint very will, today I would like to offers you an idea how to draw a picture using modern technologies. To imitate a drawing in pencil first of all need to take a digital photo and make some editing corrections in Adobe Photoshop. Open it and use filter "photocopy" (filter/sketch/photocopy) - a dialog window would appear. Scale "detail" fits with detailed elaboration of picture, and scale "darkness" fits with black color activity. Expected result you can see from the right side. Now print your edited image and put it on the table illuminated from beneath. Put new paper over the printed paper. Draw out the lines with pencil accurately by the outlines of printed image. As you can see, nowadays, drawing portraits with pencil is easy as two and two, just using modern digital technologies. Well if you can't paint very well you should train yourself. Be patient, the right person will appreciate your work, and such portrait will be a really good present.
