Maybe this is off topic,but i found one guide for the better picture from our n900
leafpad /etc/gdigicam/gdigicam-camerabin.conf
change useconfigfile=false
to
useconfigfile=true
and
[imageenc]
element=dspjpegenc
#quality=95
to
[imageenc]
element=dspjpegenc
quality=100
sorry if someone posted that before
regards
