I think photos are a really important part of personalizing any home. However, homes can often be cluttered with tons and tons of photos leaving visitors overwhelmed with where to look. So, why not pick a favorite (and fun) photo to make the focal point of a wall? One of my favorite examples is this underwater photo (above) from of Lulu de Kwiatkowski's Los Angeles home in Lonny Oct 2010.
Here is another one of my favoites, that designer and photographer Lori Andrews did of just a family's legs. (how cute?!)
This big black and white photo in an orange accented dining room is also darling.
One last example (probably price prohibitive for many), the Novogratz blew up a black and white photo to wallpaper a bedroom. (Pretty fun, until they're teenagers...)
