It is a long established fact that a reader will be distracted by the readable content of a page when looking at its layout. The point of using Lorem Ipsum is that it has a more-or-less normal distribution of letters, as opposed to using ‘Content here, content here’, making it look like readable English. Many desktop publishing packages and web page editors now use Lorem Ipsum as their default model text, and a search for ‘lorem ipsum’ will uncover many web sites still in their infancy. Various versions have evolved over the years, sometimes by accident, sometimes on purpose (injected humour and the like).
Real life businesspeople shot on location. Since these locations are the real thing, and not shot in an "office studio", high ISO levels are sometimes needed to catch the moment. The ISO range is between 250-600 so it should be fine for most usage cases. Most people won't notice anything really, but if you are a nerd like us, you can see a little noise.
