Hi guys, thanks for comments, sorry for not visiting the thread earlier!
sacx13, depends which photo you're asking about? The cameras used range from a 2MP Ricoh compact to a medium format Bronica.. (The latter is better!)
Thanks, Ck. The calendar was shot for Southampton University Students Union and all the photos were done in about 6 hours in a single day. Which meant there were about 15-20min for every group of people and meant the shoot was over before people were able to realize and have time to get embarrassed.
