“Often while traveling with a camera we arrive just as the sun slips over the horizon of a moment, too late to expose film, only time enough to expose our hearts.”
Wikipedia said that:
Photography is the art, science and practice of creating durable images by recording light or other electromagnetic radiation, either electronically by means of an image sensor or chemically by means of a light-sensitive material such as photographic film.
and for me,
Photography is a very important tool that is used to memorialize our lives and yet we do not think of it at the time that we press that shutter button. We do not realize the importance of the images until the subject of one of the images passes on and then we are left with nothing but the memories. Photography helps us relive the past, in a way to keep in touch with the past and appreciate the beautiful things that we see, knowing that someday we will not see these things anymore.
