How do I take very long exposure photos? I would like to take some long exposure photos using my Android phone (Moto DROID v1 running Android 2.2.2) of the night sky.  I experimented with the settings for the default camera app, and I found that I can set the focus to infinity, but the exposure time has only three settings: 0, +1, and +2.  If I  set the exposure to +2, I can get a recognizable photo of a full moon, but I am unable to capture a field of stars.

Is there any way to extend the exposure time beyond +2?
You cannot do this from with Settings of the default camera.

You could look at another camera app like Camera Streak (Blog).

Or you could roll your own, here is the relevant details you need to change:
