South Australian artist Ida Sophia has won the lucrative Ramsay Art Prize.
The 33-year-old was picked by a panel of national and international judges for her performance-based video work Witness, which depicts her being repeatedly submerged in water.
The video was shot in a single take at The Pool of Siloam in Beachport, on South Australia's Limestone Coast, and was influenced by her childhood experience of seeing her father's baptism and how she felt her father loved Jesus more than herself.
