Kostis was born in Athens and studied Computer Science in Crete and Lighting Design in London. Starting from 2006, live events gradually became an important part of his life. In 2009 he started taking his Canon PowerShot SX110 IS to concerts. Between 2011 and 2016 he was using an Olympus XZ-1. Since 2016 he has been using a Canon G7 X Mark II. The pictures that appear in this website were taken with one of those compact cameras, from audience positions, mostly standing and without any photo passes.
