Overcast afternoon, rain imminent, more like lingering winter than springtime. Walking home with parcels from the Castro, I took an unfamiliar side street and encountered this purple vision.
Often it comes as a surprise to me that the colors in flowers rise up better in photographs taken on cloudy or foggy San Francisco days. Bright sunny weather would seem like the best light for flowers, but in fact it tends as often as not to wash them out. With wisteria this must be especially true, where each spray contains about 27 subtle gradations in shade and intensity.
