NATURAL PHOTO SYSTEM (NP system) is a newly developed system that enables high quality non-flash photos. 135-format film camera “NATURA S”, and IS01600 color negative film “NATURA1600” are the first products for the NP system, and they are available in October 2004 in Japan. NP system maximized the high-sensitivity, fine grain and wide exposure latitude of silver halide film. The combination of IS01600 35mm film, newly developed compact camera with a F1.9 lens and a unique exposure program that controls exposure level to the over exposure depending on the light value, makes it possible to take high quality pictures without flash.
