Many things in our life are so small and tiny as we cannot see its parts with naked eyes. To reveal the details of any small thing we have to use microscope which is not possible everytime or with anything.We are able to see a cockroach or a fly or a butterfly but our eyes are not all set to see the hair on the legs of cockroach or colorful formation of wings of butterfly. Then, macro-photography is used to glance the tiny world by setting the camera very closely and zoom-in and then nothing is concealed anyway.
