rawcam 1.0.4
* Fixed the creation of the DCIM folder which was accidentally commented out
* Fixed the accelerometer based stabilization to work in all conditions
* Added a combined Accelerometer&Burst stabilization mode
* Now N900 version is again on par with N9
* N900 when quitting by closing lens cover still inhibits the regular camera from working until reboot. Currently only workaround is to go to switcher and press the x button.

Get harmattan binary from my repository and fremantle from extas-devel

I was hoping I could incorporate the function of the fremantle application lowlight into rawcam but unfortunately lowlight is not open-source. I found however this pdf which explains the algorithm. I don't know if I will find the time to decipher it, but if anybody wants to help you are very welcome to provide pseudocode for this, and I will include it in rawcam.

@Ladoga, I remember that there was a way to capture camera frames with gstreamer on the N900, specifically screen-sized ones. Writing a shell script to run the command should be trivial, and the command should work on the N9 too. This fulfills all your requirements and is easy to implement. I suggest you search for the relevant command and if you are not familliar with shell scripting, start a new thread asking for help. The result will be useful to many people.

Now it's time for a shameless plug

I was on a nokia exhibition stand and they had a "dark room" so that potential customers could compare the Lumia 920 with their mortal cameraphones, so I took the bait and tried my luck with rawcam and the N9. Here's the result
L920N9

Now the comparizon isn't completely fair because I just snapped with the L920 and I tried several times with different settings with the N9 to capture the second image. On the other hand that dark box was tailored to suit the L920 camera (thus the better whitebalance).

The L920 photo still looks better, but it seems they've gone the Kodak/Canon way and they've applied a bit more post-processing otb. It seems like some of the details have been lost (too much NR). Unfortunately I didn't take a raw picture with the N9, only JPG.

So I applied some quick steps of enhancement in gimp and got an even more close result. (Meaning that with a little optimization on the software side we can almost match the 'amazing' L920 camera)
