Finding the positives in the negatives

Heard the one about the brilliant street photographer who was anonymous in her own lifetime but who is rapidly acquiring posthumous fame due to a stash of negatives picked up by an opportunist at an auction? It's a remarkable story ripe just perfect as the subject of a documentary - so look out for Finding Vivian Maier when it sees the light of day (possibly later this year).
