This demo shows the power of sorting values first and pre-mixing puddles of paint. Easy ways to 'draw' the lily pads are discussed throughout the demo, even though the artwork is created with no preliminary drawing or toning of the canvas.
Pre-mix colors for this lesson even if you use your own photo. Lily pads are great for seeing nuance between the water and the pad (value and color). Work on seeing the 'same value, color shift' idea presented. Many students need to work on this concept and this can take time to implement in a painting.
