This paper examines the transition process that occurs when digital media appear that share functionality with established analog media. New concepts for how the new medium is represented and produced and its functionality and products may all have to be coined. A non-linear change process is presented which highlights the importance of old media metaphors for making sense of new media, processes and representations. Examples from digital photography and e-mail are presented to illustrate how new technology presents us with opportunities to examine our assumptions about artifacts and the processes that produce them and our relationship to our world.
