I was looking at
this page about the Human Planet series and the photographer Timothy Allen. If any of you get the BBC, I would think this is going to be an amazing series.
A bit of trivia...the project was 1.5 years and spread over 40 countries. He stated he likes to shoot a lot, about 10,000-20,000 images per shoot. I can only assume that each country is considered to be at least 1 shoot. That would be a minimum of 400,000 shots!!

That's like getting a 1D MKIV and going through it's shutter life of 150-200k and then going through another one. (he uses a pair of 5D MKII)
Amazing piece of work and a fascinating career.
