A striking and high-resolution black and white 6x7 medium format photograph of a historic railroad tunnel in Auburn, California, captured on Ilford XP2 Super. Part of the Structure collection, this analog study utilizes a dramatic low-angle perspective, following the leading lines of the train tracks toward the stone-masonry portal and the distant "light at the end of the tunnel." The chromogenic XP2 film captures a vast dynamic range, detailing the rugged rock cuts of the Sierra Nevada foothills and the modern graffiti that marks the industrial stone entrance. This professional study documents the enduring human impact and engineering legacy of the Northern California rail corridor, highlighting the intersection of 19th-century infrastructure and contemporary cultural layers within the Matt Haupt collection.
