Its lack of red sensitivity also means that reds and oranges in your frame are rendered darker with stronger contrast than standard panchromatic films (all other Ilford and Kentmere films are panchromatic). Ilford Ortho PLUS is DX coded for ISO 80 for daylight / natural light shooting. For tungsten work a manual ISO setting of 40 should be used. Alternatively, a 1 stop exposure correction can be made. Whether shooting at ISO 80 or 40, it can be processed as standard. Development times can be found in the technical data sheet or on the inside of the film cartons.
