Between plein air pieces I solve for the unsolved in small pieces and thumbnails. If you are in my demo in Tarnów, Poland or Toulouse, France this summer, you will see my thumbnails array of tools. 1) first piece is showing evolution to big shapes and less speak on top. Then it shows evolution of reminding myself of which car parts matter if 2 cars were to be stacked close to each other. Also quick eval between temperature of the colors- warm/cool overall? Clearly warm wins here but the cool thumbnail is the map. 2) swipe. This piece is to make sure my strokes come from my shoulder and that I can control brush right to left and left to right because when I start painting, I won’t get time to lift hand. I paint almost vertical - so speed of water has 9.81m/s^2 acceleration minus friction coefficient and scaling factor of sin(theta) to normal. All that to say, it’s fast. #nopleinnogain #ipaintlikeanengineer
