Kodachrome is a color film introduced by Eastman Kodak in 1935, known for its vibrant colors and sharp detail. It became popular for both amateur and professional photography, especially for capturing landscapes and portraits. The film used a complex development process that involved multiple chemical baths, which contributed to its unique color quality. Kodachrome was widely used until its production ceased in 2009 due to the rise of digital photography. Despite its discontinuation, it remains iconic in the history of photography, influencing how images were captured and appreciated throughout the 20th century.
