Digitally sculpting a sphenoid bone in zBrush

The sphenoid bone is my absolute favorite bone in the human body. So delicate, so beautiful, so important. I made this sphenoid bone by compositing models made from a couple different MRI DICOM datasets (OsiriX) in Zbrush and cross-referencing them with a model of the skull floor we made using photogrammetry (123D Catch).  I then scoured all the atlases I could get my hands on, looking for quality turnaround photos and illustrations of the sphenoid, and sculpted my heart away. (Special shout out to the Rohen and Thieme atlases I love so well!)

On Beauty’s Positive Exposure

I just found out about this organization, called Positive Exposure, that was created by fashion photographer Rick Guidotti to celebrate beauty. Specifically the beauty of individuals with “genetic, physical, and behavioral differences” through photography and video (as per their mission statement). According to the About Page, the organization was Guidotti’s response to the “sad and dehumanizing [images…] [i]n medical textbooks [where] children with a difference were seen as a disease, a diagnosis first, not as people.” He wanted to challenge those conceptions and educate people “to see those with differences not as victims, but kids and people first and foremost?” To do that, Guidotti said that ” The pity has to disappear. The fear has to disappear. Behavior has to change. These kids need to be seen as their parents see them, as their friends see them, as valuable and positive parts of society, as beautiful.” Truth.

The photographs created by Positive Exposure are beautiful and they truly celebrate the beauty of individuals. You can check out Positive Exposure’s Gallery to see some of them.

If you think this is as awesome as I do, then you’re in luck because Joanna Rudnick made a documentary about Guidotti’s mission called On Beauty. I can’t wait to see it.
