About the film
Lucky Super GBR 200 was a daylight colour negative still film of ISO 200, made by China Lucky Film Corporation for C-41 processing.
The earliest dated evidence for it is Lucky's own Chinese technical sheet, which was online when the Wayback Machine captured it in December 2001. Lucky aimed it at everyday colour prints, stressing saturated, bright colour and an exposure latitude of −1.5 to +3 EV. The sheet describes multi-layer red, green and blue emulsions for straight curves and wide latitude, with new-generation DIR and DIAR couplers and DIR compounds for strong interlayer effects and saturation. It also lists a UV cut and doped multilayer tabular silver halide grains that reduce high-intensity reciprocity failure with flash, with a resolution of 100 cycles per millimetre at 1000:1 but no RMS granularity. Kosmo Foto reports that Super GBR 200 sat in a range with GBR 100 and GBR 400, and that Lucky first made its colour negatives with Kodak's help under a partnership. In 2024 Lucky was considering a return to colour film production. Any later Lucky colour film is a different emulsion, not this one.

Science & sources


A daylight still-photo colour negative rated at EI 200. It prints on Fujicolor Positive F-CP 3510 by default. Its curves, spectral sensitivity and single visual MTF come from Lucky's charts; its individual dye shapes and grain are borrowed from Kodak Vision3 250D, because the sheet does not publish them.
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.
- 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 source prints one visual MTF curve, not separate red, green and blue curves. The model applies it to all three layers.
- No RMS granularity is printed. Grain is proxied from Kodak Vision3 250D (5207), so the granularity values shown are that film's, not measurements of Super GBR 200.
- The source gives no tungsten rating. The optional conversion filters use separate measured spectra; the source does not calibrate their effect on this film.
- The printed MTF rises to about 109 % at low frequencies, a sign of development adjacency effects; their width and strength are assumptions.
- The sheet describes strong interlayer effects and reduced high-intensity reciprocity failure only in words; the model simulates neither.
- Halation strength, radius and layer weights are not quantified by the datasheet. The effect of removing antihalation and the bloom response are also approximations.
- 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.
- 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.
