Kodak Professional Ektar 100 is a daylight-balanced colour negative film characterised by an ultra-vivid colour palette, high saturation, and an extremely fine grain structure. This film's smooth grain profile pairs with a micro-structure optimised T-GRAIN emulsion to make it especially well-suited to scanning applications, and advanced development accelerators offer extended versatility when making enlargements.

Ektar has a nominal sensitivity of ISO 100/21°.
