Users can edit photos via proprietary software on a Mac (a PC version will come later next year) and can share them on Facebook, where friends can interact with them by zooming in and refocusing. If the Lytro takes off, it could change the way professional photographers and even casual photo users take pictures. "It lets people shoot first and think later," says company founder Ren Ng. "Now you can take a picture and compose it in a new way."
