Rainbow, a Picture?

     I have often thought about what really happens when a picture is taken.  This poem addresses this:


                              Seeing a rainbow
                              was so important
                                      to her,
                               but she couldn't
                               always be there
                                      when it
                               appeared. One could
                               snap a picture
                                       of it
                               which would be
                               nice, yet a
                                       bit like
                                eating chocolate cake
                                and having no
                                       taste buds.
