RETOCOLOR AQUA 400 ISO 35mm Film is designed to produce subtly faded and low contrast colors in a variety of lighting conditions. When used in daylight, it imparts a cool iciness to the images, adding a grainy texture for a unique effect. This film requires standard C-41 processing, a widely available option for lab processing. The film canister also includes a DX code, already attached, to help automatic cameras set the correct ISO.
