Kodak Portra 400 is a color negative film engineered with ISO 400 sensitivity and designed to deliver a broad exposure latitude with consistent color reproduction. Its chemical emulsion is formulated to produce a fine grain structure and controlled tonal transitions across varied lighting conditions, making it a practical choice for portrait and documentary photography. It feels to me like a film stock you can never go wrong with… unless you are trying to not spend all your money on your photography hobby.
