Kodachrome 25 is one of the most historically significant film stocks ever produced. Introduced in 1936 as the world's first commercially successful color film, Kodachrome defined color photography for over seven decades. The ASA 25 version was beloved for its extraordinary sharpness, microscopic grain, and rich saturated color palette that defined National Geographic photography and fine art color work for generations. Unlike conventional color films, Kodachrome used a complex external dye injection process requiring specialized K-14 laboratory processing. Discontinued in 1987. The last Kodachrome film of any kind was processed on December 30, 2010 at Dwayne's Photo in Parsons, Kansas — the last K-14 lab on earth. This canister is a complete artifact — any film inside can never be properly developed again.
