Hi everyone,

I'm one of the developers of the FCam camera API, which we just published for the N900. The API is a joint project between Stanford University and Nokia Research Center Palo Alto. It gives you precise low-level control over the N900's camera subsystem, including RAW capture, full control over all camera parameters, and so on.

We've released a demo app called FCamera that shows off a few of these things, including an HDR viewfinder mode, auto-HDR burst capture, and lucky imaging. And it saves RAW images in the DNG format. It's up in extras-testing.

FCam is a C++ API, and works pretty well with QT (although it has no dependencies on Qt - it works just fine standalone). It depends on fcam-drivers, which are updated camera kernel modules. The development package, fcam-dev, is also available, although you might just want to download that from the project page below.
