Last fall I was amazed by the autumn foliage. It was an especially vivid season, and also Henry David Thoreau’s essay, “Autumnal Tints,” had inspired me to seek out the colors. This year the foliage has been somewhat muted. A disappointment? — only if you must have big bright shapes. Lean to focus and there’s always something to observe. I’ve found when seen up close a single maple leaf fills the field of vision, just the same as the forest from a distance.
