On the basis of this rendering, an artist then makes detailed studies of faces, hands, clothing and ornamentation. In a consequent step, he determines which colours he will use. All of the ancillary details he brings to the fore in order to create a more precise image of his design in the form of a modello. Some painters chose to do all of this preparatory work immediately on a panel or canvas. That the artists plan and realise the entire process from A to Z of their works of art is rather exceptional in the Baroque. Usually, the designer gives a faithful modello to a painting or sculpture assistant, engravers, tapestry weavers, silversmiths or a contractor who then goes to work on it. With regards to designs for prints, wall tapestries and glass panes, the design is on the same scale as the ultimate work of art. In the latter two cases, it is done with paperboard on a large scale.
