Right. However your analogy is a big fail because it is not analogous. It would be analogous to a film/digital recording of Nelson Mandela giving a speech compared to a Computer Graphic simulation of such a speech. Nice straw man you demolished.

Both film and digital photography are real things. Both record real images. The real images are the latent images created by the photon on the sensor/film as they knock out electrons. In both cases, the real image must be transformed into a visible image by conversion. In one case the conversion is chemical. In the other case the conversion is electro-mechanical.
