To Make A Pen and Ink Sketch From A Photograph
By the following method anyone can, without any knowledge of drawing, produce from a photograph a pen and ink sketch suitable for reproduction as an illustration. From the negative a silver print is made on albumen or gelatine or collodion paper. This is fixed without toning in a solution of hyposulphite of soda. It must then be thoroughly washed to remove all traces of hypo, and when dry, the outlines of the photograph are traced over with a fine pen and a waterproof ink, obtainable at any artist’s material store. If the photographer possesses a little knowledge of drawing, some of the shading can also be attempted. When the ink is dry the picture is immersed in a saturated solution of bichloride of mercury (poison) when the photograph will disappear, leaving the outline sketch intact. The picture is again well washed and dried. Newspaper sketches are often made from photographs in this manner, a zincotype being quickly produced from the drawing. Gaslight paper can also be used.
