Main Page | See live article | Alphabetical index Pencil sketching is a sketching technique. The negative image of a photograph, black and white or colour, is placed in a photographic enlarger work in a dark room. The image is projected on to the paper where the sketch is to be done. All the light shades are penciled until the paper is all the same shade. This article is a stub. You can help Wikipedia by fixing it. This article is from Wikipedia.
