Kajol, who was seen in many advertisements in the last year, shot for a campaign for an NGO to create public awareness for thyroid on Thursday despite her pregnancy.

Celebrity photographer Dabboo Ratnani who shot the print and TV ads says, "It's mostly close-ups and she's looking lovely. It's for creating awareness about thyroid and through the ad Kajol will urge people, especially women to go for check-ups.

The ad also encourages tells people that it's not like a taboo illness and also curable." Even the photographer took only half his fees as it's for a cause.

The celebrity photog who has a great rapport with the fussy actress adds that he shoots nine of her ten ads, "Her only criteria are that she should look nice and the lighting is right.

People feel Kajol is clueless about photography but that's not true. She's knows everything about angles and lighting. She enjoys discussing shots and is very interested in getting them right. She only shoots with people she trusts as doesn't like bad pictures of hers released."

He adds that Kajol prefers candid pictures to posed ones. "She likes easy and natural pictures and not stiff or staged ones with a nice ambience, music and comfortable settings. I find her really sweet to work with. When I didn't have a studio, she would come to my Khar home and often I have shot her with natural light streaming in through the window."

Dabboo adds that Kajol, who is currently expecting her second child, bonded with his little daughter Myra while shooting the public awareness film, "She loves children and keeps advising me on how to bring up my daughter."
