There was an interesting documentary on TV last night about the making of the Pirelli calendar. You can watch it here: http://www.sbs.com.au/television. It looked at the stylistic changes over the years, the photographers, the models. Although it didn't discuss the equipment I noticed that by far the majority of photographers were using Mamiya 67s (couldn't tell whether they were RB or RZ) and there wasn't a tripod in sight. They were throwing them around like point 'n' shoots. Of course, they had plenty of assistants but nevertheless their skill and ease with those big beasts was a joy to behold. It was also interesting that even into the 21st century many were still shooting film. There was a Pentax 67 in there too. The other thing that impressed me was how hard the models had to work in often difficult and dangerous conditions. Some were cavorting with wild elephants in a mud wallow, some had snakes draped over them, dead birds dripping with blood, horrendous-looking insects crawling over them and throughout it all they had to try and look at ease. They earned their money!
