Although Nokia's Camera Extras app was scheduled to hit Lumia 900 smartphones sometime next week, owners in the US and China will be pleased to know they they can get it now. Nokia has officially pushed the free app into the Windows Phone Marketplace for both regions, giving Mango-flavored Lumia users four new options for capturing photos. Along with a much-needed self-timer, you'll find three other modes: Panorama, Action Shot (for photographing fast-moving subjects) and Smart Group Shot (selects the best faces from a sequence of frames). Don't fret if you don't have a 900 or live outside of the aforementioned either -- Nokia plans to release the Scalado-bred software for all Lumia smartphones worldwide in July. Hit up the links below for more info, and be sure to let us know how it works for you in the comments.
