A haunting and high-resolution black and white 6x7 medium format photograph from deep within the railroad tunnels of Auburn, California, captured on Ilford XP2 Super. This entry in the Structure collection, "Light at the End," utilizes a dramatic low-angle perspective to emphasize the leading lines of the tracks as they disappear into a pitch-black void. The chromogenic film's exceptional latitude preserves the sharp highlights of the distant tunnel exit against the deep, rich blacks of the interior civil engineering. This professional analog study documents the monumental scale and isolation of Northern California's rail infrastructure, capturing the enduring human impact and industrial solitude of the Sierra Nevada foothills within the Matt Haupt collection.
