I have lived a stone's throw from Alamo Square Park ever since I moved to San Francisco, and see it almost every day. It's not very big, but it is on top of a high hill and in San Francisco, that means a lot. From there one can see the whole city, track the fog, and changing light. All important in mapping out a day of painting in town.
Many of these paintings were done using the limited pallete of Anders Zorn (indicated by AZ), namely black, white, red and yellow. The absence of blue causes the grey areas to act as cool blue areas, and the greens are achieved by mixing black and yellow.
