Kodak · ISO 160 Color negative
Kodak Portra 160NC
Portra 160NC launched in 1998 as one half of a deliberate split. Kodak released two 160-speed color negative stocks simultaneously: NC for Natural Color and VC for Vivid Color. The idea was that studios and editorial labs could spec the variant that matched their workflow without having to correct color in the darkroom or, later, in post. NC was the conservative choice, built for predictable, repeatable skin tones under mixed lighting.
The palette is genuinely neutral by film standards. Blues are accurate without pushing cyan. Yellows don't punch. Skin registers in a range that holds through both tungsten and daylight sources without radical color casts requiring correction at the printing stage. Commercial portrait studios in the 2000s standardized on NC because the proofing expectation matched the final deliverable closely enough that clients approved prints without the back-and-forth that racier stocks could generate.
Scan it with a good drum or flatbed and the tonal range is excellent: shadow detail opens up with modest exposure latitude, and highlights hold texture well past what most photographers expect from a 160-speed stock. The C-41 process here is straightforward and the negatives are easy to read on a light table, which matters for labs handling volume portrait and commercial work.
Kodak replaced the NC and VC lines in 2011 with the current Portra 160, which inherits the color restraint of the NC variant. Most working photographers who used NC in the late 2000s found the transition smooth; the new emulsion is finer-grained with similar color priorities. The main reason to know 160NC now is if you are working with old editorial stock or have frozen rolls from a studio archive.
Reciprocity exponent is 1.10. Zone Light Meter corrects exposures past one second using that figure.
How the app handles this stock
- Box speed: ISO 160. Picker exposes pull/push chips so you can shoot it at any speed you want and the meter follows.
- Reciprocity: Above one second the app raises metered time to the power of 1.10.
- Expired film: if you load an old roll, set the expiry year and storage in the app and the ISO scales for you. Color negative decay rates are baked in.
