Featuring the finest grain of any 400-speed black and white film in the world, Kodak Ektapan 400 produces striking, highly detailed images with strong contrast and superior clarity. Incorporating a T-Grain emulsion with tabular silver halide crystals that enhance light absorption, Ektapan 400 exhibits a clean, low-grain appearance with increased sharpness and more distinct edges in comparison to traditional cubic-grain films. Ektapan 400's impressive resolving power and broad tonal range make it well-suited for a wide range of photographic applications, including architectural, portrait, landscape, commercial, and more. Its nominal sensitivity of ISO 400/27° makes it ideal for a variety of lighting conditions, from sunny daytime exteriors to dimly lit interiors.
