#       Program: wlcamera.py
#    Written By: George McGinn
#                <gjmcginn@icloud.com>
#  Date Created: 11/25/2021
#
#   Description: Wildlife Cam Kit script to shoot still images from a wildlife/trail cam,
#                like the Naturebytes camera system. Script will work with any PI camera.
#                Uses the PiCamera Python module instead of raspistill for greater control
#                over the imaging process.
#
# Version 1.0 - Created 11/25/2021
#
# CHANGE LOG
#########################################################################################
# 11/25/2021 GJM - New Program.
# 11/28/2021 GJM - #1) Fixed syntax error with camera.resolution and added PIN 27 to Motion
#                      Sensor detection.
#                  #2) Added the ability to take a burst of 5 images every .05 seconds
#                      after a PIR sensor activates (to capture a series of images for
#                      faster moving wildlife, like birds at a bird feeder/bath).
# 11/30/2021 GJM - Fixed the filename as it added .jpg twice (found in testing)
#                  Changed the camera.capture to add format=png to take png images.
