If you're still around, your script doesn't seem to focus properly. It seems to use the exposure settings from the last photo taken with the camera app, but not the focus settings.

I made myself a tripod mount using an old hair clip and a piece from a broken webcam, and took a picture of a very backlit miniature. The miniature was sharply in focus. I then used the script to take three photos, but the miniature was blurry in all three!
