""" simple point-and-shoot camera example. With NTP and internal RTC to
 add timestamp to photo filenames. Must install adafruit_ntp library!
 Example code assumes WIFI credentials are properly setup and web workflow
 enabled in settings.toml. If not, you'll need to add code to manually connect
 to your network."""
