Nokia has extended its Camera app beyond PureView smartphones and on to the majority of Lumia handsets, adding more-advanced camera features to the cheaper line-up.

The beta is available from the Nokia Beta Labs website, where "you will get frequent updates with the latest features and improvements, but there could be bugs".

The Nokia Camera app was announced in October for the camera-focused Lumia 1020 and Lumia 1520 phablet. It combines the existing Smart, Pro and Video modes, and adds multiple shooting modes available at a touch: standard, night and sports modes are optimised for specific scenes. Additionally, you can now shoot in raw file format so photos can be edited in Photoshop.

Essentially, Nokia has taken the camera app available by default on Lumia smartphones and has beefed it up with additional features.

Whether you're into point-and-shoot auto, want to specify the specific mode, or go into manual control to adjust the autofocus area with a tap of the screen or via a manual focus slider, the Pro camera user interface makes light work of it all. Specific colours and greyscale can also be focused on.

The Nokia Camera app supports the Lumia 520, 521, 620, 625, 720, 810, 820, and 822. A final version of the app is expected to land sometime early next year. Nokia suggests you check out the beta in the meantime, if you're not afraid of a few bugs.
