The colour and saturation of the images you posted are due to:
1) the illumination at the scene; and
2) the process used to come up with a display image.
The two images below were shot on Portra 160NC - the slightly less saturated version of the current Portra 160. The difference in their appearance is due mostly to the placement and diffusion of the light source.
I see. Thanks.
