Portra 160 is indeed good for skin tones. It also has the benefit of being on the side of low contrast as a result of capturing a huge subject brightness range that digital can't. Such as a person under a tree in dappled light, digital would have blown highlights; Portra 160 would handle it gently and smoothly, just like tmax400 in pyrocat HD would handle it fine. The contrast and color saturation can be easily bumped up if you're using a hybrid workflow.

Outdoor in sun, it handles shadows and sunny highlights with ease:


Outdoors in gray weather, Portra 160 is VERY subtle in tone.
