Kodak Portra 400 and Kodak Ektar 100 are both color negative films processed in C-41, but they have different personalities. Portra 400 is a faster film with soft, natural color and wide exposure flexibility, while Ektar 100 is a slower film with vivid color and very fine grain. Choose Portra for portraits, indoor light and mixed conditions; choose Ektar for bright landscapes, travel and architecture.
Speed and Light
The speed difference shapes everything else. At ISO 400, Portra handles shade, cloudy days and window light with ease. At ISO 100, Ektar works best in bright daylight or on a tripod. As a general first guess, Ektar in full sun suits an aperture around f/8 with a shutter speed near 1/125, while Portra gives you two extra stops to work with.
Color and Contrast
- Portra 400: muted, natural tones and smooth skin rendering. It looks gentle and consistent across lighting conditions.
- Ektar 100: strong, vivid color and higher contrast. Blues, greens and reds stand out.
- Grain: both are fine, and Ektar is generally regarded as having especially fine grain for large prints.
- Latitude: Portra is more forgiving of exposure errors. Ektar prefers careful metering.

How to Decide
- Think about when you shoot. Mostly midday sun favors Ektar; varied light favors Portra.
- Consider your subjects. People usually look better on Portra.
- If you carry one film only, Portra is the more flexible all-rounder.
- If you carry two, load Ektar for scenery days and Portra for everything else.
It also helps to think about scanning and printing. Both films respond well to careful scanning, and a lab that offers neutral settings will show you the real difference between them. Ektar can reward you with strong prints from small frames, while Portra gives you flexible files that are easy to adjust. Keep notes on each roll, and compare them after a few outings instead of judging from a single frame. We have not used either film ourselves, so confirm formats and availability on the maker’s page.
FAQ
Can I use Ektar for portraits?
You can, but the intense color may make skin look warm or heavy. Some photographers enjoy that look, while many prefer Portra for people.
Does Portra work well in bright sun?
Yes. You may need a fast shutter speed or a smaller aperture to avoid overexposure, though its latitude helps.
The Short Version
Portra 400 is the flexible, natural-looking film for people and mixed light. Ektar 100 is the vivid, fine-grained film for bright scenery. Choose by subject and the light you usually shoot in.
