What is there to be sad about? He can only be congratulated, not everyone is given the chance to live to 81. Many die before they even reach 60. A person who dies at his age is a lucky person who got lucky.
As for his contribution to photography, I believe that he did not cover the third world war, the hot phase of which has been going on in Ukraine since 2014. Where was he with his camera all these years? Where?
He photographed the genocide in Rwanda in 1994, but for some reason decided to ignore and pass by the genocide in Ukraine.
Therefore, I believe that he lived the last 11 years of his life in vain. And did not give the world what he was destined for.
