Wannabe models, be careful. To be the next Katrina Kaif or Deepika Padukone, you may have to pose smilingly at the edge of a dangerous cliff or look sensuous as killer whales jump behind you.

While shooting under hostile conditions for the coveted Kingfisher Calendar, many bikini bombshells feel a chill running down their spine, said photographer Atul Kasbekar. "We have done real shoots with sharks, killer whales, at jail cells and even at the edge of a cliff. The models we look for should be comfortable in such situations. They have to enjoy the adrenaline rush and stay composed," Kasbekar said.
