The collection of photos, taken by members of the International Association of Professional Birth Photographers, aims to show that birth photography isn't "gross" or "distasteful".
"There is much more to birth photography than the actual moment of birth,” the association's founder Lyndsay Stradtner wrote on her blog. "So much more.
"It’s the birth environment, the light in the room, the details, the comings and goings of those who are there."
The association has more than 1,400 members in 37 countries and was founded by Stradtner of Life in Motion Photography in 2010.
