About the film
Kodak Portra 160 is a daylight ISO 160 colour negative for Process C-41, and Kodak dates it to 2011: Eastman Kodak's release of 21 February that year introduced it at the WPPI show in Las Vegas, for sale from March in 35 mm, 120/220, 4x5 and 8x10.
Before it, Kodak's 160-speed Portra films were 160NC and 160VC, listed in one family data sheet with 400NC, 400VC and Portra 800. The release said Portra 160 would replace both 160NC and 160VC as their stock ran out. Kodak credited its finer grain to Advanced Cubic Emulsions and said it shared the Vision film technology of the Portra 400 launched in 2010. It was aimed at portrait, fashion and commercial work, in the studio or on location. Kodak stressed finer grain for scanning and enlargement in current workflows, while keeping the natural skin tones of the Portra family. Kodak Alaris now publishes the data sheet, revised in January 2025, and its curves are Portra 160's own drawings rather than copies of 160NC's.

The look
Kodak Portra 160 is a daylight colour negative rated ISO 160, made for portrait, fashion and commercial work in the studio or on location. Kodak gave it finer grain for scanning and enlargement while keeping the natural skin tones of the Portra family. Ashigrain renders it as a scan for your grade.






Best for
- Studio and location portraits
- Fashion and commercial work
- Big enlargements and high-resolution scans

Science & sources


A daylight still-photo colour negative rated at ISO 160, shown as a scan. Its curves, spectral sensitivity and MTF are digitised from Kodak's current sheet. Its grain and individual dye shapes are borrowed from Kodak Vision3 250D (5207), because the sheet publishes neither an RMS granularity nor separate dye curves.
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). 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.
- Colour-print timing and scan balance under arbitrary lighting are modelled. Scanner colour balance has no standard physical unit.
- 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 sheet prints only a Print Grain Index, which Kodak says cannot be compared with RMS granularity. Grain is proxied from Kodak Vision3 250D (5207), so the granularity values shown are that film's, not measurements of Portra 160.
- Only a midscale neutral and a minimum-density spectrum are printed, not separate cyan, magenta and yellow dye spectra. The individual dye shapes are borrowed from Kodak Vision3 250D (5207), a proxy rather than this film's dyes.
- No push or pull data are published. Push amounts, interlayer effects and grain size are approximations.
- The characteristic response beyond log H −3.03 to 0.95 is extrapolated.
- No antihalation layer is named; an undercoat is assumed. Halation strength, radius, layer weights and bloom are not measured.
- The sheet's reciprocity guidance is recorded but not modelled.
- The default output is a scan. Scan balance has no standard unit and is modelled.
- The printer lamp and filter spectra and the Status A grey aim used in this preview are approximated; the source does not publish the required spectral or laboratory aim data.
Reciprocity: not modelled. Exposure time has no effect on this film.
