The pictures are taken in between shoots and are candid shots of his interaction with his co-stars, an idea borrowed from his mother, Sharmila Tagore, who also has personal pictures with her co-stars from various films.
Some of his pictures include Vidya Balan during the Parineeta shoot, a picture of Akshaye Khanna playing chess and a few rare photos of Katrina Kaif.
Among his pictures, is one of his girlfriend, Kareena Kapoor in a sari for which he intends to get a silver frame. Saif doesn't want to give out any of the pictures for publishing and will probably use them for an autobiography/biography, if he happens to write one in future.
And if the book idea doesn't work out, the pictures could always be put on the walls of his Pataudi home.
