I went back to the site THE OP referred us to and looked at every single image I could find: in my first visit I had missed a section. I think that web site was shot by an intermediate-type photographer, and I'd say every image was directed to at least some degree, but the level of the work is not "high-grade, commercial pro" photography, which is what we USED TO see on web sites and in brochures, before the flood of d-slr shooters brought in loads of people who really do not have the knowledge or skills or gear to do higher-level commercial photography. But then again, not every company sees the value in higher-quality photos, and some will eagerly accept UGC or user-generated content, and also will hire low-end shooters to do their photos; not every company has a $10,000 to $30,000 budget for photography, that's just a fact.
The best lifestyle images convey a sense of idyllic perfection, and they give that (false) sense of everything being super-awesome, totally satisfying, just peachy-keen. The best "lifestyle" images are I think, created by very skilled photographers, and they have good lighting, good posing of the people, attractive people, clear emphasis on what the photo means, what the significance is, and so on. The best lifestyle images have been directed by the photographer, and everything in the shot works together, to create a generalized good feeling.
