Sharon Beals is a San Francisco based photographer who has photographed nest and eggs specimens collected over the last two centuries at The California Academy of Sciences, The Museum of Vertebrate Zoology, and The Western Foundation of Vertebrate Zoology.

Art and science collide in photographer Tim Tadder’s series “Water Wigs” and “Water Wigs Women”. In these perfectly timed photographs, Tadder captures his models wearing hair that’s made out of water.

There isn’t exactly a college out there for face painting so Elsa Rhae Pageler‘s talent is as raw as it comes. Perhaps what’s even more amazing is that the video editor and producer from Kansas City graduated with a degree in Film and Media Studies and only does face painting and airbrushing as a side job. An application may take anywhere from 1 to 3 hours and apart from outside gigs, she features video tutorials on her YouTube channel showing how she paints herself to recreate video game and fictional characters.
