Using more than 1,000 photos taken over a period of three years, a woman from Sydney, Australia has documented her transformation from man to woman in a one-minute video clip.

Ashley Caccamo, 24, began her gender transformation from man to woman on Dec. 8, 2009. As the images fly by in the video she posted to YouTube, her features change, as does her expression - into an ever-so-slight smile.

"I have had FFS [facial feminization surgery] during the process," Caccamo said on her YouTube page. " I started roughly around when I was 20 - 21 years of age."

The video clip begins with a notice that it has a "T" rating - approved for all transgendered people. Caccamo set the clip to "Girl" by the Beatles.

Facial feminization surgery often includes procedures such as a brow lift, rhinoplasty, and lip augmentation.
