About the film
Kodak Professional Ektachrome E100VS is a daylight colour transparency film for Process E-6.
No source read dates its launch, but the earliest dated evidence found is Kodak's E-163 data sheet of December 1998, so the film existed by 1998. Kodak made it for location and studio work that wanted very vivid, saturated colour, the VS in its name, with a neutral grey scale. Kodak credited that saturation to its own Color Amplifying Technology, and the fine grain and sharpness to T-Grain emulsions. It came on acetate base in 135 and 35 mm × 100 ft rolls, with a thinner base in 120 and 220. Kodak's notice of 1 March 2012 ended E100VS together with E100G and Elite Chrome Extra Color 100, with stock expected to last six to nine months. Kodak cited falling sales and complex manufacturing for ending the film.

The look
Kodak Ektachrome E100VS is a daylight colour transparency film rated ISO 100, viewed directly as the positive. The VS in its name marks very vivid, saturated colour, which it pairs with a neutral grey scale, steep contrast and very fine grain for location and studio work.

Science & sources


A daylight colour reversal film rated at ISO 100, shown directly without a print stage. Its curves, spectral sensitivity, dyes, separate red, green and blue MTF curves and RMS granularity are digitised from Kodak's sheet; the granularity, printed at a gross density, is converted to net density.
Response curves and the evidence behind the model
Compare manufacturer data with Ashigrain’s response on the same axes. These curves show how the model is calibrated to its sources; they do not establish a match to photographed film.
Characteristic response
RMS granularity
Density variation (σD) measured through a 48 µm aperture. Where the datasheet gives a single grain value, the response away from that point is an approximation.

Model limits
These images show the film model in use. Spectral response, lighting and viewing conditions include approximations. Halation, bloom, grain size, weave and flicker are not fully measured for each film. The look of real film also depends on development and print timing.
- Custom lighting spectra, camera metering and the spectral reflectance inferred from fixed-white-balance footage are assumptions used by the model, not measurements of this film.
- Conversion-filter spectra (80A for daylight films under tungsten, 85 for tungsten films in daylight) come from separate measured filter data, not from this film’s source. Applying those filters to this film remains modelled.
- The only grain value is RMS granularity 11 × 10⁻³, read at a gross (not net) visual density of 1.0. Its conversion to net density and the response away from that point are modelled.
- Push and pull have no published curves for this film and use a generic model.
- The sheet's reciprocity data are recorded but not modelled.
- Individual dye amounts, layer interactions and push/pull behaviour are approximated where the datasheet provides no calibration. Grain size is assumed; published RMS granularity does not specify dye-cloud size.
- Characteristic response outside the published exposure range is an extrapolation, not measured film data.
- Halation strength, radius and layer weights are not quantified by the datasheet. The effect of removing antihalation and the bloom response are also approximations.
- The available sources do not measure veiling flare during projection. The model approximates its contribution to lifted blacks on screen, so the result is not a measured projection contrast.
Reciprocity: not modelled. Exposure time has no effect on this film.
