Kodak Portra 400UC

Portra 400UC was Kodak's strange experiment: take the Portra family, which existed specifically for accurate skin tones, and push the saturation hard enough to compete with reversal film. Released on September 30, 2002 for fashion, advertising, and editorial shooters who needed color that punched on the printed page, the UC carried wide latitude and decent skin rendering alongside a palette closer to Velvia than to any other negative stock in production.

The UC label confused everyone. Working portrait photographers who picked it up expecting normal Portra behavior found shadows that were deeper, greens that ran emerald, and a contrast curve that did not flatter most subjects. Pros who needed the saturation already had reversal film. The audience for what UC actually offered turned out to be smaller than Kodak hoped. Within roughly two years the film was rebranded as Kodak Professional Ultra Color 400UC, formally exited from the Portra line, and aimed at the architecture and product market it had been designed for in the first place.

Grain was tight for the speed, sitting closer to the published numbers for ISO 160 than for 400, which made it useful for art directors wanting both color pop and clean print enlargements. Compared to the Ektar 100 that Kodak released years later, UC was two stops faster and not quite as saturated, which is part of why Ektar took over the niche entirely.

Kodak ended 120 production first and then phased the 35mm out as well. Final stock disappeared from retail sometime in the late 2000s.

Reciprocity exponent is 1.10. Zone Light Meter applies the correction past one second: a 30-second metered exposure climbs to about 35 seconds at the negative. Shot in good light, where this film made the most sense, the correction is irrelevant. For long-exposure interior work the math stays gentle.
