Review this film:
Ektachrome 100d is a slide film with a far lower contrast than any other slide film in production today. This means it is much more forgiving than films such as Velvia or Provia. In comparison to negative film, 100d is nevertheless much more sensitive to overexposure. Take good care in metering your scene and avoid using cameras with unreliable light meters.
Ektachrome, while being more flexible than other slide films, is nevertheless far less forgiving than negative film. Therefore, it is recommended to use a camera with an accurate light meter, and ideally a lens with settable half or 1/3 aperture stops.
