Photographer Marco Antonio Sanchez is something of a purist. Not a purist in the sense of photography, per se, because photography as such can be an artifice too. No, Sanchez is a purist in terms of his love affair with the subject, and thus the subjective and singularly attuned eye of the photographer. In his Fotoseptiembre offering “Catálogo De Maravillas: Puebla, Las Siete Regiones,” curated by Jake Pacheco, Sanchez positions himself, and by extension the viewer, in the vantage point of an innocent (albeit technically adept) wanderer. Though he hails from Puebla originally, Sanchez seeks to capture the power of discovering the intimate and sublime treasures of the Mexican state’s seven distinct regions. His approach, this situation between familiarity and exploratory intuition results in a whimsical, subjective, and wholly breathtaking photo-journey through a rich and diverse territory. Free, 6:30pm Wed, Sept. 14, UNAM San Antonio, 600 Hemisfair Plaza Way, Building 333, (210) 222-8626, fotoseptiembreusa.com. On view through October 20.
