That camera set up seems masochistic : ) I can't imagine shooting a documentary in raw on the 5DII and trying to focus with that VAF filter in the way. Add Minolta adapted lenses on top of it- this is really quite a contraption and my hats off to them for pulling it off! I got into environmental documentary making because too many of the ones I watched had a shallow understanding of the issues, particularly their social and political contexts. This film seems to have fallen into similar traps by conflating scientific and political disagreement. When one is not an expert it is very important to figure out who is credible and not to rely on expert sources who are not experts on the subject matter at hand, or even still current in their fields. Sadly Dyson falls into that latter camp and his criticism of climate models is simplistic and ideologically driven. For a brief treatment of Freeman Dyson's views on climate change and other environmental problems written by working climate scientists, see this post over on RealClimate. RealClimate is also a place to go behind the news headlines and overly credulous assessments of single scientific papers by the press, and to ask questions. The scientists there personally answered my questions related to global warming and helped me understand a disagreement between scientists I had been talking to. http://www.realclimate.org/index.php/archives/2011/02/the-starship-vs-spaceship-earth/
