The scientific illustration is based in two phases, one of hand drawing, the study of the piece, of the material, the different shapes of the object, colors and textures. This hand first draw it’s made with pencils or watercolors and its a technical draw of the object. After it, comes the vectorization, the digitalization of the drawing for scientific publications of archaeology which is a draw made with Adobe Illustrator and a tablet graphic.
If you have not drawn it, you have not seen it.
Johann W. von Goethe
