Ross Addison is alleged to have conned two women and a 14-year-old girl into sending him pictures and videos.
He faces a total of six charges relating to the setting up of a fake modelling agency between January 1, 2006 and September 16, 2011.
Addison denied all the charges at Perth Sheriff Court yesterday and a trial was set for early next year.
Addison, of Kinross, is alleged to have duped his first victim from his home and Donald Street, Dunfermline, between 2006 and 2011.
It is alleged he obtained explicit videos and images of the woman by fraud by pretending to her by e-mail and social media that he was a modelling talent scout.
He is accused of concealing his true identity before offering to pay for the explicit sexual images - and having no intention of paying.
It is alleged he set up an email account and the woman involved then sent images and videos to him in the expectation she would be paid.
Similar charges apply concerning another woman between January 1, 2008 and September 16, 2011.
It is also alleged that between January 1, 2010 and November 30, 2010 at both addresses, and in Consett, County Durham, he used lewd and indecent practices towards a 14-year-old girl and that between December 1, 2010 and September 16, 2011 he intentionally caused her to participate in sexual activity via webcam. He is also alleged to have possessed indecent images of children at his home on September 16, 2011.
