Her name is Natsumi, a female photographer living in Tokyo, Japan, along with her two cats. I've browse through her lovely photoblog, presenting her own Self-portrait photographs of herself levetating and cats around her (not levetating). All the photos are her own creation, utilizing on the timer on her camera or her friends pressing the shutter button just as she is levetating on the right spot (and perfect angle). Totally loving her cute idea.
