Trevor asks: What's wrong with tracing paper? Scott wanted to know the bleaching method. It has a very different look to a traced image and for some tonally busy images, drawing directly on the print is a lot easier. there's also more mystique behind the produced sketch - the paper is clearly not as translucent as graph paper so it appears not to have been traced - it looks more like an original artwork and suggests a skilled line drawing was created. some skill is required though for it to look good. you need a sketch artists skills and eye to know what to draw in and what to leave out. karl
