Jim Leggitt developed a digital watercolor method that takes the hybrid process of 3D modeling and hand-illustration one step further. The process involves using SketchUp to model a site and compose a view, exporting the lines and image separately, then combining and hand-coloring the print before applying a watercolor filter in Photoshop. This gives the final image the authentic appearance of a hand-painted watercolor while retaining the benefits of 3D modeling for the underlying composition. The method was applied to illustrate a children's hospital healing garden.
