Taking inspiration from Impressionist painters, this paper presents a project creating a light painting combining traditional oil technique with mathematical strategies and latest technology. As an artist with plein air and studio practice, I emphasize the importance of value relationships in defining lightness and darkness within a composition. In this paper, I describe a project transforming an oil painting into a model that can be 3D printed. The uniqueness of this result is that the forms and composition are only recognizable if the 3D print is held against light. In this work, I further explore the Impressionists’ goal to depict the world in innovative ways.
