Peta's work has a focus on aerial views and with her 30+ years experience in Cartographic mapping is a major influence in her work. Peta often refers to her mind as being blank or void of light due to a condition called Aphantasia that renders Peta's ability to visualise impossible. At first the darkness had a negative impact on Peta's creativity, but she has learned to accept that it is part of what makes her unique.
