Im looking for an app that will let me take a quick pic from a hot key. And by quick pic i mean a picture without acctually opening the view finder for the camera, just snap a quick picture of what ever the camera is pointed at.

I don't have a short cut or hot key on my phone

but a long press on the volume down button for a fast picture without even opening the view or having to unlock the phone would be nice

If something like this does not really exist then atleast an app that would quick pic from a widget.
