I continue to paint the wetlands around Lake Tippecanoe even though I find these paintings to be challenging. The photographs are dominated by greens, even the water appears greenish in midwestern lakes, so I try to push the colors. I painted this at night and used artificial lights to brighten my workspace. As this painting progressed, it appeared lighter than I wanted so I kept darkening the colors. However, when the artificial lights were turned off, the painting looked more like dusk than midday. Any suggestions for lighting a workspace?
