 Once the notion of digital media is revealed to be no more confused or mysterious than the familiar notion of literary media, its irreducible role in appreciation becomes apparent. To take just one example, proper appreciation of movies in the digital age depends on recognizing that digital movie-making tools do not just make traditional movie-making easier; they also present new creative possibilities and challenges. Given the maturity and mass-art status of the cinematic art form, it is easy to take for granted the medium of moving imagery; we may think we know precisely its limits, and we may even think we have seen everything that can be done with it. The digital medium is different, however, and digital cinema is in both the medium of moving imagery and the digital medium.
