RESEARCH REVIEW / 15 SEPTEMBER 2026
60 product records. 68 references. 14 approximate overlays; no verified six-hue measurement sets.
The video reports saturation decreases of 21% for Color '92, 18% for Portra 400 and 16% for original Phoenix. ColorPlus's 8% and Lomography 400's 8.2% have unresolved signs. UltraMax's spoken +7.15% conflicts with the ranking's unsigned presentation. Source comparison, 28:52.
The comparison shapes remain useful, so the 14 original overlays are retained as approximate video transcriptions. They are stored separately from measurements, excluded from calculations, and visibly labeled. Their coordinates still lack patch-level extraction records; decimal places do not establish confidence or error bounds.
Characteristic curves describe density against log exposure. Spectral sensitivity describes wavelength response. Neither is a finished sRGB palette: development, illumination, dyes, scanner response, inversion and grading all matter. Portra 400 technical data.
The tested Candido 800T is separate from CineStill 800T. Original Phoenix is separate from Phoenix II; Color '92 is separate from Sun-kissed. WOLFEN NC500 is ISO 400, despite its name. NC500 manufacturer sheet.
100 * (S_film / S_reference - 1). Undefined when reference saturation is zero; unstable near zero. This is not the same as a percentage-point difference.D = -log10(T). Density is logarithmic transmission, not an RGB channel value or a saturation multiplier.The red, yellow, green, cyan, blue and magenta interface colors are category labels, not measured SpyderCHECKR swatches. A ratio-one baseline is a mathematical reference, not a calibrated physical target. HSL is not perceptually uniform. W3C color specification.
Use the correct target edition and patch IDs, documented reference values and illuminant, a color-managed scan pipeline, and matched comparison conditions. Evaluate lightness, chroma and hue, with a validated color-difference implementation such as CIEDE2000 where appropriate. A screen capture cannot establish a film's spectral response. Datacolor target guide / Colour implementations.
The creator's project page offers project resources, but no reproducible raw-patch table was located. Presets and modeled profiles must not be relabeled as independent measurements.

The first-party product page identifies Eastman 5294 as the underlying film.
ISO 100, C-41, 35mm and 120 product specification. A 400-speed film guide is not a substitute for this stock's documentation.
Stock-specific ISO 800 color-negative reference; no measured per-hue dataset.
Exposure, processing and sensitometric curves; not a final scanned RGB rendition.
Manufacturer curves and exposure guidance. No PARVEC-style saturation percentages.
Characteristic and spectral response data; sheet sizes are listed in the current color-film catalog.
Sensitometry, exposure and processing documentation.
Manufacturer technical data, independent of the video's scanning workflow.
Product and format information; qualitative marketing descriptions are not measured color deltas.
Current product listing. Kept separate from Portra; this page alone does not establish an independently new emulsion or interchangeable measurements.

April 2026. EI 200 daylight, ECN-2; sensitometry, spectral and dye-density curves. Highlight behavior and post-production differ from VISION3.
5294/7294 motion-picture product; do not silently transfer E100 still-film measurements.
2025 catalog-number transition. Record backing generation and processing; not every current VISION3 roll can be assumed to carry the old rem-jet backing.
Historical C200, not proof of equivalence to current US Fujifilm 200 or of current availability.
Historical product curves; keep distinct from current Fujifilm 400.
Historical professional negative-film technical reference; not a stock-availability notice.
Reversal-film technical curves and exposure guidance; historical formats may no longer be available.

Creative redscale exposure and processing information; intentional color shifts are not color-accuracy defects.
False-color rendering depends on exposure and scanning; not a natural-color target.
Scanner and inversion settings materially affect the apparent film palette.

US aerial-derived stock, hand-spooled in Finland. The supplier does not identify the exact aerial emulsion here; do not assume Aerocolor identity.
Medium-format motion-film respool reference. Processing and batch identity must accompany any color measurement.
Process-dependent rating: 640 in C-41 or 500 in ECN-2. Keep AHU generation distinct from older AMBER T800.
