Please view details at: https://grandcentralatelier.org/online_demo/working-up-opwerken/ The Dutch still life painters of the 17th century generally painted in three layers. Once their drawing was finished the artist proceeded with the dead coloring (dood-verf), a thin transparent layer of paint that described the various elements in the composition in very basic terms. This layer could be painted in color or in monochrome. Once completed and dry, the picture was ready for the finishing layer or layers. This ‘working up’ (opwerken) stage developed the forms indicated in the dead coloring or underpainting layer to a higher degree of finish through a combination of opaque and transparent paint applications. Depending on the subject and/or intent of the artist, a following layer of paint could be added to further refine a given part or subject. In this demonstration, I will show how I have adopted this ‘working up’ method to making my own pictures. In this two part series, you will see how I execute the two finishing layers on an already completed underpainting. In short, I will show how I go from the underpainting to the finish.
