It's possible it is Provia if she is using a newer Rollei with modern coatings. Either way, it is likely filtered a tad warm via a filter or natural light, I would be doing the same with Provia. Also consider the light, light is everything in a photograph, it is likely the second biggest oversight I see in enthusiast work that is lacking, the first being composition and third being exposure...
