Kodak Portra 160NC does look a little blah for landscapes, but it is often very good for still lifes. It has about the most accurate color I've seen, but accuracy may not be what's wanted most in the prints. I've found that the UltraColor films (100UC and 400UC) do quite well for landscapes, although the most recent versions may be a bit too much. The new Portra 400VC is more saturated than the older version, and it may be about what you need. If you are using 35mm, you may want to investigate the Kodak Gold films (amateur line available in camera stores and supermarkets). They are excellent films with high saturation and a bit more contrast than the Portra line. Although the UC and VC films have high color saturation, they are low contrast films. If you are printing on traditional papers, this may a problem. I think the look of Endura Supra is fine, but you might want the higher contrast of Endura Ultra.
