I spent a dream-day in San Francisco earlier this month, photographing a handful of sweet families at the top of Potrero Hill. In between shoots, we explored the Dogpatch and stuffed ourselves with Humphrey Slocumb ice cream. It really says something about the love between this brother and sister that, despite that unbelievable gauzy light, the perfect swing, and the wind-weathered trees, my favorite part of these photos is their incredible vibe. They are crazy about each other. So may it ever be.
