First, Chapter 2 intro assignment. The tonal value study was much harder than it looked. When I finished all the patterns on the squares, cut them apart and rearranged them I discovered that I had clusters of tones rather than a nice transition from light to dark. Sooooo… tangleations of some of them to adjust the tone a bit. I suppose I could have continued adjusting the values with some shading but I wanted to leave them unshaded. End result was that there was an improved gradient that still had clusters. I may well repeat this exercise in the future.
