There is much to learn from these little exercises. I discovered how hard it can be to see the minor variations in values and how pushing from cool to warm can make a huge difference in the perception of those values. I was captivated by the incandescant light in this still life by Cook.

I hadn't fully appreciated what a delicious color Viridian can be until I copied this little painting from Lipking. Prior to this I mostly used it for mixing, but it makes wonderful sea greens and grayed aquas.
I also figured out tilting the camera slightly downward when taking a photo of a finished painting helps to avoid catching the glare from every brushstroke.
