Nokia recently launched a new photography app called Creative studio which is available in the Windows Phone Marketplace exclusively for its Lumia handsets. Part panorama stitcher, part photo filter and part image editor, the app lets you take new pictures or chose shots from existing albums and tweak them to your heart's content. It features ten Instagram-like effects (including vignette and auto-enhance) plus seven common adjustments (such as crop and sharpness). We took the app for a spin and the UI is pretty slick, with an optional side-by-side before and after view of the photo you are currently editing. Once done, you have the option to continue applying additional effects and making further adjustments, save the image or share it. Twitter, Flickr and Facebook are supported, but sadly there's no integration with Windows Phone's People Hub -- you'll have to login to each service in the app itself. Check out the screen shots in the gallery below and hit the break for more impressions and some samples.
