About the film
Fujicolor Reala 500D is a high-speed, daylight-balanced colour camera negative rated EI 500, coded Type 8592 in 35 mm and 8692 in 16 mm.
It carries Fujifilm's fourth colour-sensitive layer and dates from c. 2001. In a SMPTE conference paper published in November 2001, Fuji Photo Film engineers presented it as a newly developed film. They aimed it at the growing use of fast negatives and daylight lamps, claiming the highest speed of any daylight motion-picture film. They also claimed faithful colour, good behaviour in mixed light and better skin tones. Fujifilm's later product page called it the first high-speed daylight motion-picture film. It was made by Fuji Photo Film, now FUJIFILM Corporation. Fujifilm's archived list of discontinued films includes Reala 500D among the films whose production had ended by 31 March 2013.

The look
Fujicolor Reala 500D is a daylight-balanced colour negative rated EI 500, or EI 125 under tungsten with an 80A filter. Fujifilm built in a fourth, cyan-sensitive colour layer to keep colour faithful in mixed light. It prints on Fujifilm Eterna-CP 3513DI by default.

Science & sources


A daylight-balanced colour negative with an exposure index of 500. Its datasheet documents a fourth, cyan-sensitive layer; the model uses only three layers, omitting the fourth. Its dye shapes are borrowed from Kodak Vision3 250D, and it prints on Fujifilm Eterna-CP 3513DI by default.
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.
- Colour-print timing and scan balance under arbitrary lighting are modelled. Scanner colour balance has no standard physical unit.
- The sheet documents a fourth, cyan-sensitive layer but gives no data on how strongly it acts on the red record. The model keeps three dye layers; the fourth layer is not modelled.
- The source publishes one RMS granularity value, 4.0 × 10⁻³. The granularity response away from that level is modelled, not a digitised grain curve.
- The source publishes one square-wave contrast transfer function at visual diffuse density 0.9, not separate red, green and blue sine-wave MTF measurements.
- 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.
- The 2005 sheet and the KB-111E3 edition print the same curves on exposure axes about 0.5 to 0.8 log H apart. The model moves the 2005 curves 0.813 log H lower, onto the KB-111E3 axis.
- The prescribed Kodak 80A filter uses separately measured transmission data. Grain size, push/pull behaviour and interlayer effects are approximations.
- The sheet prints reciprocity corrections at a few exposure times; the correction between them is interpolated.
- Characteristic response outside the published exposure range is an extrapolation, not measured film data.
- The source does not identify an antihalation layer. Rem-jet is assumed; halation strength, radius, layer weights and bloom are not measured.
- The available documents do not name a development process for this film. ECN-2 is assumed, not confirmed by those sources.
- 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: modelled from 1/1000 s to 1 s, following the datasheet's corrections for long and short exposures. Exposure time stops at the ends of that range.
