Digital Dilemmas

Computer imagery is fraught with divers conundrums and paradoxes associated with the fact that it is both abstract and concrete. It confounds familiar ways of understanding appearance and reality. We can begin to resolve the perplexity by using the idea of recursion to contrast digital imaging with picturing. It is particularly useful to explore the concept of an interface and to study its role in the imaging system. Digital images cannot be understood outside the context of the complete interactive system in which they occur.
