Music and Photographs

We do not treat the circular object of the CD as a representation of the sound that is “burned” into it. The zeroes and ones do not in any way represent the sounds of the music, though everyone agrees that they somehow carry them.

Why then do we say that a photograph represents what it shows? Can’t we say, in a similar vain, that it does not represent the world that it makes us see, but that it carries it?
