# camera.wait_for_event() function waits for a capture trigger
# to arrive and returns the folder and name of the new file.
# When it does, camera.file_get() is used to download
# the image directly from the camera, without using SD
# card
#
# camera.trigger_capture() or Trigger Button on the
# camera can be used to start capturing.
#
# gp_capture_image_and_download() method takes about 2 seconds
# to process since it saves the image to SD CARD
# first then downloads it, which takes a lot of time.
# *******************************************************
# Additional comment by Jim Easterbrook: My cameras save to SD card or
# RAM according to the capture target setting. Use of
# camera.wait_for_event() or camera.capture() makes no difference to
# where the image is saved.
