Last week I participated in Steelville Missouri's plein air competition. This was painted at sunset on an 11" x 14" panel. The rules stated that it must be painted entirely plein air, so not touch ups later. Painting sunsets require planning by drawing in the shapes before. I could plan that the area on the left will remain dark, but the rest changes quickly. I think I should have gone to this location two days. The first day with a small study then, hopefully the next day the weather repeats itself for me to paint the larger image.
