Everything is artifact. Color is illusion... With photography there is a workflow. Some practitioners consider certain elements of that workflow essentual. Others have different views. Perhaps we could interpret "No Postwork" as being true to traditional practices. As I'm not sure what this means, perhaps we could require of each submitter a short paragraph explaining what workflow was used, and why the artist feels the result is true to traditional practices? Any follow-up discussion I'm sure will be interesting and valuable.
