Kodak Professional Ektachrome E100 is a daylight-balanced color transparency film characterized by its extremely fine grain structure, vibrant color rendering, and overall low contrast profile. The lower contrast values contribute to a wide dynamic range and a neutral tonal scale for greater color accuracy, and a low D-min helps to ensure brighter, whiter whites. It has a medium-speed nominal sensitivity of ISO 100/21° when developed in E-6 process, and the smooth grain profile pairs with a micro-structure optimized T-GRAIN emulsion to make it especially well-suited to scanning applications.
