title: RaspiStill - Quality/Size Miss Match - File too big
body: <p>Using RaspiStill through a python process shell to take a picture with JPG encoding. I am getting a file that is over two megs. When I reduce the quality down to 50% the file size of the picture taken only drops the by about 200K, or less then a ten percent decrease. When I take that original 2 meg+ file and save it through Paint.Net with the quality set at 85 percent it drops the file size down to 300k, or almost a 90% decrease.</p>
  
  <p>Am I doing something wrong, or is there something wrong with the encoder in RaspiStill?</p>
  
  <p>Below is command line that I use to take the picture:
  pi@raspberrypi ~/Development/tests $ <strong>raspistill -n -t 100 -q 50 -e jpg -o fullsizejpgsethalfquality.jpg</strong></p>
  
  <p>Resulting File Size: 2052kb
  Resaving the same file though Paint.Net at 85% quality: 319kb</p>
  
  <p>Thoughts?</p>
