Art in times of post-production

The technological advances and globalised economy have made digital technology readily available for large parts of the world population, regardless of geographic location. Meanwhile visual art is heavily dependent on digital equipment such as digital cameras, editing programs and means of projection. Yet in countries devastated by war (such as Iraq, Afganistan, Palestine) these means are extremely limited. So how does that influence the prodution of art in these countries? And the western perception of non-western art? I am going to work with the screening of a video work, by an afgan artist, that has been post-produced here in the UK, because the curator did not feel It was good enough for the museum it was intended to be shown in. Is there a western filter on contemporary art, that focuses on technical quality? Are economic limitations an impediment for producing art that deals with the division between first and third world? What disourses regulate the field of socially commited art? I would like to recieve some opinions on the matter, and possibly tips on how to approach the subject. The idea is basically to show the video piece simultaneausly in its "before" and "after" state, with an ensuing discussion.
