Kodak Portra is a family of daylight-balanced professional color negative films originally introduced in 1998 made mainly for portrait and wedding applications.
[2][3] The film has been upgraded by newer versions several times in the last few years, starting in 2006,[4] to improve grain and scanning performance.
Kodak lists finer grain, improved sharpness over 400 NC and naturally rendered skin tones as some of the improvements over the existing NC and VC line.
[8] Kodak also lists improved scanning performance as a feature.
The "NC" and "VC" varieties of the film were introduced to address the need for different levels of contrast and color saturation when printing, and adjusting these image attributes tend to be more difficult with traditional color darkroom printing than with digital imaging.
