A serene and high-resolution 6x7 medium format film photograph of the decommissioned Rancho Seco cooling towers in Sacramento County, California, captured on Fuji Pro 400H. This entry in the Structure collection highlights the monolithic, hyperbolic concrete towers rising above the golden, dry grass of the Sacramento Valley. The soft, pastel color palette of the Fuji Pro 400H film emphasizes the contrast between the historic industrial architecture of the former nuclear station and the modern solar infrastructure now occupying the site. This professional analog study documents the enduring human impact and monumental scale of Northern California’s energy heritage, capturing the geometric precision of these regional landmarks within the Matt Haupt collection.
