"Jeffrey Fraenkel opened his eponymous gallery when he was just 24, and over the course of the last 35 years has built his brand as one of the best photography galleries in the country. With a formidable list of artists (he's shown everyone from Sol LeWitt to Diane Arbus, and he handles the estate of Garry Wineograd) and a slew of loyal collectors, he's had an enormous influence on many significant photography collections in the city. Currently on show: Carrie Mae Weems curates the Diane Arbus photographs that speak to her the most. Don't miss the Fraenkel Gallery's satellite pop-up space in Presidio Heights. The idea behind it is somewhat grab-and-go: each piece—from the likes of Diane Arbus, Adam Fuss, and Adam Levitt—is already framed for instant purchase. "
